Cleaning my Spa filter every few days
My spa filter gets dirty every few days and i have to clean it. This seems excessive to me, I never had to clean them this much before.
What chems are you using - and how often are you using the spa? Also who else uses the spa?
Well I use chlorine and brite and clear. I have a new ozone unit. My daughter has moved back in so we do have one more user.
I see a couple of potential issues. One is the Bright and Clear clarifier - use it sparingly - you have an ozonator, let it do the work. If you use too much B&C it can gum up your filter, and also if you have more users than usual and if they have make-up, or sun tan lotions, or get their hair wet by dunking their head in the spa water. These oily products wind up in your water - and if your using Bright and Clear daily - this will coagulate the small particles in the filter before the ozone has a chance to oxidize it out. Second issue is the added bather -- yes we use that term for a reason. Just one new person can totally change your spas water make up, and if that one person has a friend over it gets even worse. You should lay down some rules -- 1 - quick rinse before you get into the spa-- it’s not a bath tub so don’t use it like it is. 2-- No lotions or make up in the spa. 3--after each use have the daughter toss in a table spoon of chlorine powder. Since you don’t know how often she is really using the spa, put that responsibility on her, that way you can maintain based on your use. And, it’s also just possible that the spa filter is spent. When they reach the end of their life, they need more cleaning. When you are cleaning it twice as often as before, it’s time for a new spa filter cartridge.
Wow, i had no idea. Thanks for the info. I will give it a try .
Filter Cartridge Size and Union Leak
Local spa dealer wants to upsell from 25 sq foot filter - is that worth doing? Secondly, I have an older Nordic hot tub - noticed slight leak on outlet side of heater. It has a "split" type of union that screws together, unable to stop leak. I tightened it - got better but won't seal. Is this a standard oring size or best to pull it & match it? The oring fits a gecko powerpack / heater assy. I loosened this union only once since purchase when I replaced the pressure / flow switch.
For many common spa filter sizes, you can get the same cartridge but with more pleats. More pleats means more square footage of filter area. They cost more, but can be worth it for longer filter runs and better water quality. It can also reduce nuisance Low Flow errors, when a dirty spa filter is the cause. For the split nut union o-ring, most are rather standard, for 1.5”, 2” or 2.5” sizes. Union o-rings can last for 10-15 years, but if old when opened, they can be hard to seal again. A Teflon lube can be used on these o-rings to improve the seal and protect the rubber. You can find the correct size o-ring in the plumbing unions page on our website.
Adding External Spa Filter
Our Southwest spa only has the 200 micron Sock filter and it does not do a sufficient job. I want to add an external pressure filter. Where can I get a pressure filter housing with 2 inch in and out?
There are a variety of external filters that would work like the Waterway 50 sf topload filter, or the Rainbow 75 sq ft, both with 2” connections. You may be able to fit one of these under your filter, or you can cut holes in the cabinet to run two 2” pipes in and out to the filter, sitting outside the cabinet. Cut the pipe after the pump, but before the heater, to divert the water in/out of the filter, and bring the water back into the line near the same point. Use as few 90’s as possible, to reduce flow restriction.
2006 Maxus Filter Cycling
My spa keeps going on and off (cycling) trying to start the filter cycle. There are no error messages, do anyone know what could be the cause?
Try disconnecting the small remote topside panel and see if it still does this. If so, then disconnect the ozone unit and see if it stops. If continues then it may be the circuit board. Incorrect power supply, loose power connections, or faulty motor switch could also cause cycling.
Hot Tub Filter Frozen, Help!
Our power went out while we were out of town for 4 days, and we came home to a frozen hot tub, partially thawing out in 40 degree temps. From what I can see, (and I can’t see much), the spa filter is cracked, and the pipe in front of the pump is cracked, or shattered would be more accurate. We are in the process of heating it up and slowly draining the tub, what else might we be in for, or how should we test the tub? Hot Spring Prodigy tub.
You may be lucky and there may be no more damage than what you can see, but I can’t promise you anything. Start by buying a new spa filter assembly, and any spa plumbing fittings you need to make the plumbing repair into the pump. It’s probably good that’s where it broke since it is usually the lowest point in the system, which helps drain down before more damage occurs. You may need pvc pipe, couplings, and perhaps a union to fix. For the filter you will also need some couplings and pipe, and PVC glue and primer, to install the new filter. Afterwards, slowly fill up the tub about halfway, or stop if you see leaks sooner. If no leaks after standing half full for several hours, fill it up the rest of the way. Look closely inside each step with a flashlight, and feeling with your hands, for any leaks. If there are leaks in the pipes that run around the spa, that will show up as a wet spot on that side of the spa. Hopefully not!
Spa Filter Leaking
I’ve always had trouble with getting my spa filter to seal up again after cleaning the cartridge. Is there some trick? It’s a type of filter with a large black ring at the top that tightens up against an oring. There’s a little knob on top. I don’t see a name on it.
Sounds like a top load spa filter, and yes they can be sometimes tricky to seal up fully. First make sure the filter cartridge is seated firmly and properly inside as you tighten up the filter lock ring. The o-ring should be tight, if it’s loose and sloppy, replace the filter o-ring. The lock nut, or large black ring should not be cracked – you’d probably notice that if it was. Opening up the air bleeder (knob on top) may help get a better seal, as would a new filter and air knob o-ring and lube on the o-ring. For those with small hands, placing a large block of wood or bricks under the filter can free up a hand while you turn the lock nut ring. Finally, it’s got to be tight! If it still won’t seal, consider replacing the entire filter assembly, either the head (lid) or body may be warped or threads may be stripped.
Spa Filter Body has Crack
Marquis Spa, 2003. I noticed a small leak around my spa filter, and upon closer inspection, found a small crack about 1 inch long, coming from the hole where the pipe is screwed in, at the bottom. Can this be fixed? It’s a very small leak now, but concerned that it may blow out.
These types of cracks are not too uncommon on spa filters. It can be caused by overtightening the fitting into the filter usually, but other stresses may come into play, especially if it appears years after installation. A repair to the filter body may not be successful, especially for a pressure filter (installed after the pump), whereas a cracked filter on the suction side of the pump is more easily repaired. You may be able to repair small cracks like this with JB Weld or I’ve even used Super Glue. Tighten the fitting more to open the crack just a fraction of a mm more, and then squeeze the superglue into the crack and then untighten the fitting quickly, all the way out. If the crack extends into the inside of the filter body, then a successful repair may not be likely, and replacing with a new spa filter body may be the best route.
Spa Filter Cartridges Stained
We took our filter cartridges out for cleaning and noticed a light brown stain to them. We’ve never had this before, what could be causing the color, and are the filters damaged now? We have an acrylic spa and always have clear water.
Most spa filter stains are nothing to be alarmed about, and don’t usually affect the filter cartridge. They could be iron stains, from the water, or some other source of iron introduced to the water, from outside, or possibly some steel in the spa system. Could also be just dirt, if the cover was open during a windy day, or may I say that it could also be dirty spa users? If it’s too much stain for that, it could be a chemical reaction, if you had recently added many chemicals to the spa in a short time. Spa filters can be cleaned in Spa Filter Cleaner to remove mineral and metal stains. You can use a product like Metal Gon to keep metals in solution, so it won’t happen again, if it is metal staining that is.
