In my 10g I have 2 x 13watt 6500k CFL's and I dose 1.3-1.4ml of excel and 0.17-0.2ml of comprehensive daily. The daily dosing of the comprehensive add's up to the recommended weekly dose. I believe that dosing daily is better.

Anyway, I have GSA on most of my plants and on my glass. I was told that PO4 will stop the GSA from growing.

Is that true?
Where can I get PO4?
Should I increase my current dosings?
What should I do?
