    Does Filter Cleaner cause Algae?

    When I was out buying chemicals for the pool for a year (I wanted to buy everything in one shot, or close to it), I grabbed a bottle of filter cleaner since we'd been having some filter problems.

    However, when I looked at the bottle, the cleaner apparently has phosphates in it. I'm fairly certain phosphates are a major source of food to algae. Anyone ever look at how using one of these cleaners is potentially feeding algae in your pool?

    Hi, Rob,

    Don't know if the filter cleaner causes algae but I do know you do not need it. If your pool has enough Cl to prevent algae, so will your filter.
