If you are not having algae problems, I would not worry about the phosphate level. If you do start having problems, check EVERYTHING else before doing the phos. procedure. Be sure all other levels are in check & most of all...follow the instructions given here on the site. These guys (& gals) know what they are doing.

I spent about 1 1/2 summers fighting reoccuring algae & following the advice here on the site before finally deciding my phosphate level was the problem. Hopefully I now have that problem in check & do not have to do the phosfloc again.
