The Secret to Hot Tub Water Chemistry

December 9th, 2013 by

The secret to spa and hot tub chemistry? It’s not sold in a bottle, or a fancy egg shaped container. It’s not a magical potion that you drop into the spa, or pour in once a month.

My friends, listen closely – the secret to clean and clear hot tub water is a multi-faceted approach. It’s may not be easy, and it’s not especially rapid, but it’s truly a miracle.

Come closer, I want to whisper the secret to hot water perfection. The secret is …

“TEST AND BALANCE YOUR SPA WATER CHEMISTRY WITH REGULARITY”

 

Of course, you also need good filtration, with a relatively new spa filter cartridge. Replace every 12-24 mos. And, you also need to run the filter pump every day. I run my spa circulation pump 24 hrs per day.

Testing Spa Water?

Most people just use spa test strips, and they are a lot simpler to use than the dropper type of spa test kits. If you want greater accuracy, you can use the Tru Test digital test strip reader, which is great for those with poor eyesight or some level of color blindness. Use a spa test strip that will test not only for pH and bromine, but also for calcium hardness and total alkalinity. I recommend the 6-in-1 test strips by AquaChek.

Balanced Spa Water?

“Balanced” spa water essentially means that your pH, Alkalinity and Calcium Hardness are within the proper range. Adjusting the levels should go hand in hand with testing. Use a pH decreaser if your pH or alkalinity is too high. If your calcium hardness is too high, as it is in many parts of the country, use Calcium Control.

Sanitation is also a very important part of water balance. Keep a consistent sanitizer (bromine or chlorine) level in your spa. Augmenting it with minerals or ozone will make the water more forgiving of slip ups or occasional low sanitizer levels. Use spa shock after every use to kill bacteria.

That’s it – that’s the secret. Test and Balance, with regularity. But you probably knew that already…

The Chlorine Free Spa – Is it Possible?

July 22nd, 2013 by

no-chlorine

It’s a common question that we get in our call center – can I run my spa (or hot tub) without chlorine? My quick and smart answer is usually “sure, you can use bromine!” Then they say “isn’t that the same thing?” It’s not really, as bromine has less of a smell, is not quite as harsh on skin and hair, and has other advantages over chlorine.

But seriously – the real answer is Yes!, you can run your spa without chlorine, or bromine, and still have a safe and sanitary spa. It requires using some modified methods, to make sure that pathogens don’t thrive – but it can be successfully done. Here’s how.

 

Replace your Filter Cartridge More Frequently

For most spas under halogen treatment (chlorine or bromine), I recommend that the spa filter cartridge be replaced every 12-24 months, depending on it’s size, and on how much the spa is used. For those who wish to go chlorine free in the spa or hot tub, I’d recommend that you double the frequency, and replace your spa filter every 6-12 months.

Some spa filters are available with more square footage. When you search for a replacement spa filter, by dimensions, model number or cartridge number, you may see two spa filters listed that have the same dimensions, but one costs more. The more expensive spa cart will have more pleats and thus more surface area, which will do a better job of filtering.

Drain your Spa or Hot Tub More Frequently

Draining the water out of your spa should be done every 4-6 months, depending on your rate of usage, or if the water goes bad. For those using a non-chlorine method in the spa, increase the frequency to every 2- 3 months, or at least every 4 months.

When draining a non-chlorine spa, be sure to use a Spa Purge product to remove any build up inside the pipes, hoses and jets of your spa. Without a halogen residual, biofilms can form faster and create a bio-hazard in your spa water. I use Jet Clean every other time that I drain my spa, to keep organics and oils from building up in hidden crevices.

Ozone + Minerals

DEL Ozone MCD-50, it's what I use on my spa

For a spa that doesn’t use chlorine or bromine, you need something to kill bather waste and bacteria. My recommendation is to use a spa ozonator and a mineral sanitizer, like Nature2 or Spa Frog. The combination of these two – an ozone sanitizer and a mineral purifier, takes care of most disease causing bacteria.

Check on your ozonator regularly to be sure that it’s on and operational, and replace the mineral cartridge as directed, to keep a proper amount of silver and copper ions working. These two treatments working together will do most of the job in keeping your spa water healthy.

Non-Chlorine Shock

cense

Ozone + Minerals do most of the job, but to be sure, you need to oxidize the water, or shock the spa. Non-chlorine shock has no odor, and does not affect water chemistry. You can use the spa immediately after treating the water.

My recommendation is to use a few tablespoons of non-chlorine shock after every spa use, or at least weekly to control and destroy any pathogenic microbes that are able to get around the ozone and mineral treatment.  Also known as MPS, Zodiac Cense is a great product that will oxidize quickly and also adds a nice scent to the water.

Keep your Spa Water Balanced

This is important no matter what your spa sanitation method is, but especially when you are operating a chlorine free spa or hot tub. Maintain your pH level at 7.2-7.5, your Alkalinity at 80-120 and your Hardness at 180-220. Use fresh test strips or fresh reagents and test your spa water at least twice per week, adding water balance chemicals as needed.

Shower before using the Spa

please-showerI know some people (ok, I’ve done it too) who treat their hot tub like a big bathtub. After working in the yard all day, or dancing all night – they jump in the spa to “clean off”. Well, when you bring perspiration, body oils, make up, or if you’ve gone to the bathroom (#2), without washing yourself, this creates a large sanitizer demand in the water.

I’m not saying you must always shower before using the spa, but if you don’t – be sure to give it a good shocking afterwards with MPS.

It can be awkward to ask your friends to shower before coming over, so using an Enzyme product can help break down oils and organics and retain healthy spa water that all can enjoy.

And that’s it! You can successfully operate a healthy spa or hot tub without using chlorine and bromine, if you follow these steps above.

Identify Your Spa Part or Hot Tub Part

March 24th, 2011 by

spa pumps and motors

 

One of the hardest things about selling spa parts for the spa industry is that there are 1,000s upon 1,000s of spa parts from all kinds of different manufacturers. Because of this, it has been very difficult to have all of those parts listed on our site.

In most circumstances, however, we can get you the spa part you need, even when you can’t find it on our website, or even on any website.For example. most Hot Springs, Sundance, Jacuzzi, and Balboa parts aren’t listed on our site but we have extensive catalogs and databases we can use to locate these parts for you.

Another place on our site that doesn’t always have every part listed is the Spa Jet section. Most jets come in a variety of colors and textures. Because of that we don’t have the ability to have all of these jets on our site but if you happen to be in this section and find a jet that looks similar to yours but perhaps isn’t the right color don’t hesitate to call in or send us an email. Most likely we will have the jet that you need available.

We can even obtain parts officially de-listed as Obsolete, when stock still exists in distribution. Many times, a comparable part used and made by a different manufacturer may work for older, de-listed and obsolete spa parts.

And then there are just those hot tub parts that are from smaller manufacturers, from very old spas or maybe you just don’t know where to look. The best thing to do in those situations is to email us a picture along with the measurements and any numbers that happen to be listed on the part. From there our experienced technicians and staff should be able to match the part for you.

So again – if you’re looking for a hot tub part, no matter how rare, or difficult it is to find – we are here to help you find the correct spa parts – fast!

Installing a Spa or Hot Tub Ozone Injector

March 18th, 2011 by

One of the greatest items to ever come out for a hot tub has to be a spa ozonator. They have the ability to kill the majority of the bacteria in the water as well as significantly reduce the amount of other chemicals that have to be used in the water. The only problem is that it is very difficult to disperse the O3 gas into the system if you aren’t pre plumbed for ozone.

We were getting so many calls for this that we actually built a spa ozone injector kit that will allow the ozone to be injected into the water in a way that is even more effective than if your spa was actually pre plumbed for ozone. If you have 1.5 plumbing you would use part # HTW-OIM15 and if you have 2 inch plumbing you would use part # HTW-OIM2.

To install the spa injector kit, locate a length of pipe AFTER the filter and heater where you install the manifold in an upright position, as shown below. It measures approximately 15″ long and 5″ tall, so you need a clear section of pipe that’s around 16″ that you can cut into. In cases where there is no room, you may have to reroute the return line slightly, to create the space needed for the ozone manifold.ozone-injection-manifold

After locating a suitable location, all you do is cut the ozone venturi manifold (shown above) into your plumbing with a hacksaw. The pipe that is cut out should be about 3″ shorter than the overall length of the manifold, so the pipe will slip into both ends of the manifold, 1.5″ on each side.

Use pipe cleaner or primer and then glue the manifold in place with fresh PVC glue. Connect your new spa ozonator hose to the injector and you’re ready to go. The Ozonator unit should be mounted somewhere nearby, in reach of the ozone hose.

I get calls all the time where people are asking for an ozonator and they don’t even realize that it has to be pre plumbed and you could hear the defeat in their voice when I ask. But then when I tell them we have a device that will allow them to use the ozonator you could hear them perk up again. It’s a good feeling to know that we could help people find what they are looking for when they don’t even know they needed it.

So if you ever have any questions about ozone or the different ozone systems or injection manifolds that we have available – don’t hesitate to call, we at www.hottubworks.com are here to help you out.

Titanium Heater Elements and Ozone Seals

March 11th, 2011 by

Some spa and hot tub manufacturers are offering Ozone generators and/or Salt Water systems to sanitize the water. Although beneficial to water quality, salt and ozone can be detrimental to equipment like standard heater elements and standard pump seals.

To combat this I suggest you use Titanium heater elements and Salt/Ozone pump seals; which are more resistant than the standard versions to the corrosive effects of ozone and salt.

Flothru Heater Element

These heater elements are more expensive, being made from Titanium and all… but if you’re replacing a standard element every 1-2 years, there can be a quick payback in a few years. The ozone grade pump shaft seals are only a few dollars more than standard grade.

So, if your spa heating element look deteriorated and corroded, and you use salt and/or ozone to sanitize, my recommendation is to replace with a version that can withstand the salts in the water.

If your shaft seal is failing, and you use ozone in the water, look for a softening and puckering of the rubber portions of the shaft seal, or possibly corrosion on the spring portion.

Ozone and Minerals for Spas & Hot Tubs

February 17th, 2011 by

ozoneMineral Sanitizers (Nature2, Frog Floating System, Sundance Spas Sunpurity, Hot Spring AG Mineral Purifier) is offered as an alternative sanitation system for spas and pools, with promises of cleaner water without the drawbacks of chlorine. However, these Mineral Sanitizers recognize that they do not oxidize all the organics that a spa may contain, so it recommends using its product ‘Cense’ as the required oxidizer (a version of MSP, or monopersulfate).

We have nothing against MSP, but why not have the best oxidizer you can have, without adding ANY more chemicals? It’s not just DEL saying this. Here’s the assessment of freedrinkingwater.com:

What is Ozone for Spas?

“Ozone, fed into the water continuously by an Ozone generator, is the strongest oxidizer for pool [or spa] water treatment. …Ozone has a minimal effect on pH and water chemistry.”

The bottom line for spa and pool disinfection is that ozone is the strongest, broad-spectrum oxidizer that can be delivered simply and reliably. Ozone combines well with Mineral Sanitizers (Nature2, Frog Floating System, Sundance Spas Sunpurity, Hot Spring AG Mineral Purifier) minerals to cover the gaps in sanitation left by Mineral Sanitizers alone.

What is a Mineral Sanitizer?

Mineral Sanitizers are a “mineral bed” that is installed in your spa circulation to deposit silver and copper ions into the water to kill bacteria and algae, respectively. This is distinct from ionizing systems because the minerals are deposited through the flow of water through a cartridge rather than an electrical ionization process. Mineral Sanitizers shares some benefits with Ozone in that neither of them relies on excessive use of chemicals like chlorine that can have harmful byproducts when used at high enough doses to be effective.

Is Ozone and a Mineral Sanitizer Your Best Option?

No disinfection system is perfect, but if your criteria are for a simple and effective disinfection routine that produces clean, fresh smelling water with minimal harmful byproducts, start with Ozone. Whether you choose to supplement it with Mineral Sanitizers (Nature2, Frog Floating System, Sundance Spas Sunpurity, Hot Spring AG Mineral Purifier) or a small residual level of chlorine, you will be able to maintain fresh, safe water in your spa.

We have traditionally recommended a strong Ozone system coupled with a small residual amount of chlorine (maintained at about 3 ppm for spas, depending on your typical usage) for a simple, low cost way to keep spa water pure. The chemicals and the tests they need are widely available and understood. But if a Mineral Sanitizer appeals to you, we know it can also work.

Thanks;

Cal Spas “Lifetime” Warranty – Shorter than it Seems

December 9th, 2010 by

spa-warranty“Lifetime” warranty can be slippery, especially when a dealer is carrying out the warranty on behalf of the manufacturer. When you buy a new spa, read the warranty carefully, so you know what to expect.

In this case, a Cal Spas dealer told a spa owner that the spa part that failed was no longer under warranty, and she paid full price for the new spa heater.

Glad to see that Cal Spas did the right thing by this customer. Dealers may make less money on a warranty repair than on selling a new replacement spa part – should also do the right thing, and Cal Spas needs to see to that.

Here’s the Story:

When Bridget DeZiel’s hot tub turned cold earlier this fall, she figured the lifetime warranty meant she would get a new heater gratis. Yet the Bloomington woman paid $250 to replace the unit because she was told that “lifetime” on her eight-year-old Cal Spas hot tub meant seven years.

The definition of lifetime is slippery when it comes to product warranties. Manufacturers often mean the expected lifespan of the product, or they could mean the time it’s owned by its original buyer, according to the Federal Trade Commission. The least common usage is the lifetime of the owner, the FTC says.

In DeZiel’s case, the dealer made a mistake, because lifetime really meant lifetime and DeZiel should have paid only the labor cost, according to Cal Spas spokeswoman Courtney Salas. The Pomona, Calif.-based company has contacted its Minnesota distributors to correct these misinterpretations, Salas said.

As for DeZiel’s overpayment, “we’ll take care of it,” Salas said.

What surprises have you encountered with lifetime warranties? Most lifetime warranties are not transferable, or they may only be for the “expected life” of the product. Or, is it for the lifetime of the original purchaser? Many questions – read the warranty carefully before purchase, and ask questions if unclear.

And, if a dealer gives you an unsatisfactory response, take your warranty claim directly to the manufacturer.

 

Spa Ozone – Using Ozone in Spas & Hot Tubs

September 21st, 2010 by

ozone

Ozone is a great way to sanitize your spa or hot tub. It kills quickly and cleanly, with no byproducts – doesn’t affect water chemistry, and can be produced for just pennies per day!

Most new spas will have an ozonator, with lower end models offering it as an option. You can add a spa ozonator at any time to an existing spa. Ozone will reduce the bromine or chlorine needed, and give a noticeable shine and clarity to any spa or hot tub.

inventor of ozone christian-friedrich-schonbein

Ozone was discovered by German scientist Christian Friedrich Schönbein in the 1840s when he identified a unique odor during electrolysis and electrical sparking experiments. He recognized the scent as the same odor found after a lightening flash and named the substance ozone.

Ozone is created when oxygen molecules are split, by a high-energy electrical discharge, resulting in two individual oxygen atoms and those individual oxygen atoms unite with remaining oxygen molecules to produce a three-atom molecule of ozone.

The weak bond holding ozone’s third oxygen atom causes the molecule to be extremely unstable and thus, very effective as an oxidizer.

An oxidation reaction occurs upon any collision between an ozone molecule and an organic molecule, such as bacteria, viruses, fungus and algae, where the oxygen atom held by the weak bond splits off and only oxygen is left behind.

Ozone Benefits

  • It’s a natural purifier as no harmful chemical by-products are created during purification, making it environmentally friendly.
  • Eliminates chloramines, chlorine by-products that can cause skin irritations and illness, and their off-gas odor.
  • Oxidizes hydrogen sulfides, iron, manganese, arsenic and most chlorinated hydrocarbons found in water.

Ozone Facts

  • In 1906, the city of Nice, France built the first water purification plant to utilize ozone.
  • Safe for mammals and marine life, ozone is used in zoos and aquariums.
  • Ozone has been purifying bottled water since 1982.
  • Since 1984, all Olympic Games competition pools have been sanitized with ozone.
  • In 2001, the FDA allowed the use of ozone as a direct food additive and ozone can safely be used as on food equipment surfaces.
  • In the pool and spa industry, ozone has been used for more than 75 years as the most powerful oxidizer for a swimming pool or spa.
