Guys I have a 150 gal system that has been setup for a year after starting over. I started new with Marco and BRS rock. I keep my husbandry up on my tank and I do a 30gal wc every 2 weeks.. I tested my water tonite and these are my parameters using all Salifert test kits except for P04.

CA 500
KH 8.3
KH II (older kit) 7.7/8
MG 1230 (dosed tonite)
P04 .08

Could the P04 be the source of my algae? I do run GAC in my Magnum canister filter and a TLF cannister and GFO in a TLF as well.

Probably. If you have more than just a little algae and can still measure phosphate, you may have an issue. Nitrates could also be adding to the problem.
