Effect of PO4 on GSA
As far as I'm seeing in my tank, dosing of PO4 only inhibits GSA growth, and doesn't rid it. I'm currently dosing EI in a 36 bowfront (18" tall), 2x T5HO as lighting with good reflectors for 10hrs, CO2 in the green-yellow.
I've been getting plenty of GSA on my crypts and it just seems to not go away even with increase of PO4 and decrease of NO3. Am I not hitting a critical PO4 level to kill the algae, or will I need to just remove the leaves and maintain PO4 levels?
Any experiences with this would help.
