If I understand it correctly, the deal with phosphates is that they are food for the algae and the idea is to reduce the food and starve em. Pffft, quicker, cheaper and easier to just kill the algae with chlorine instead of adding another chemical to the soup. If algae is growing your sanitation level is too low for everything else anyway.

LOL. If the pool store asks about chlorine, I tell them I use sodium hypoclorite. Most stores know prefectly well bleach is a lower concentrate of the same stuff they sell.
