After battling algae outbreaks for all too long, I finally wised
up and tested my (filtered and presumably clean) tap water.
Nitrates were in the low 20's, and phosphate was too high (I
forget exact reading). I began to use phosphate resin in my
canister filter, and the results were almost immediate. I have
not had an algae outbreak since then (about a year). The plants
are growing so strongly that they use up all the nitrates and I
now add more to the tank in PMDD. I recently stopped using the
phosphate resin, since I suspected that the plants would use
whatever was in the water. So far so good, some slight green
spot algae on the glass but nothing else. I stand ready with
the resin if there is another outbreak.
Perhaps this approach will work for you too. I do use CO2
injection, which keeps the plants photosynthesizing at a good
rate so that nitrates are used quickly. Hope this helps.
