White Cloudy Water

1. SLOW the water flow. Over-sized pumps force dead algae through under-sized sand filters.
2. Use the polyquat - it *may* help.

The bad news? It appears that the process of forcing algae through sand may fragment the dead bits into even SMALLER and harder to filter bits.

As an alternative:
1. Put the filter on recirculate
2. Add the polyquat (label sized dose, not the whole bottle!)
3. Mix for 4 hours and then turn the pump OFF.
4. Wait 24 hours, and see if the algae is settling.
5. If the algae DOES settle, wait, then vacuum to WASTE.
6. BUT . . . maintain chlorine levels with bleach while the pump is off.

Will do. Thanks very much for the advice!

Ben, i tried lowering the PH to 7.0 for a couple of days to burn off calcium, but that did not help, so I think you are right (and I am wrong) about it being a mix of calcium and baking soda that is causing the cloudy water. Last night I added the 60% poly, ran the pump for 4 hours on recirculate, then shut it off. This afternoon it finally looks like the water is clearing up - I can see the bottom for the first time in two weeks and it appears there are little piles of debris. I will wait a few more hours to see if the water continues to clear, and the as you said, I will vacuum to waste. Thanks very much for all of your advice! Seems like 60% poly works better as a clarifier then the stuff that is sold as a clarifier.

It's a pretty good clarifier.

Back in the day when Buckman still held a patent on it, they sold it as a microbiocide under the label WSCP, and as clarifier under a different label for 50% less. It was during that period that requirements for MSDS info was first being enforced widely, and when I got my hands on the sheets for the two products, I recognized the labeling difference. Since I was not selling the product, but using in directly in large commercial pools, I purchased a couple of 55 gallon drums of the 'clarifier' for use as, well, an 'anti-algae clarifer'!

Buckman caught on to this practice fairly quickly. Apparently some resellers were packaging polyquat, but buying half of the stock as WSCP and half as the clarifier. Buckman did NOT approve!
