Thread: Small fines/sand in water

I have a 1991 Sundance Marin. It has been maintained quite well over the years and is still working! However, I am now getting small white and black 'fines/sand' in the water. I've drained & cleaned it numerous times in a row. Nothing works, it keeps coming back. I throughly clean and replace the filter and after each filling,I checked for anything in the water from the faucet, 'nothing'.
COULD SOME OF THE INTERNAL LINES BE BREAKING DOWN? If it is all PVC I can't imagine that happening. Is there a product I can use that will clean the lines for me?

Couple things we need to verify. Do the black particles smear like grease? Do the white particles feel like rubber? Have you changed the brand of chemicals recently?

I have a similar problem with my HotSpring spa - small, fine white-beige sand crystals. I change the water and it appears to work for a while and then they start to "grow" all over the inside of the spa. I use Spa Down because of extremely hard water, use a calcium and iron filter when I fill the spa.
I'm pretty sure it is probably the water, chemicals, or some cross reactivity but any suggestions on how to make it stop? I live in a cold climate so changing the water in the middle of winter isn't an option.

Has this been happening for a while now? Have you changed the brand of spa chemicals that you are currently using? I would recommend to use a quality spa chemical. You can find cheaper chemicals out there but a lot of times these will contain fillers and leave by products behind. A quality chemical may cost more but in the long run you use less because they aren't filled with fillers.
