I have a 14 gallon cube tank (see my build thread tag to the left) housing a green BTA and a rose BTA. The tank was set up in August, and NO3 has been 0 (unmeasurable) for the past couple weeks (Red Sea Pro and NYOS kits) and Phosphate is at 0.23 (Hanna ULR meter). I have long hair algae taking firm root on the rockwork despite having a couple golf balls of Chaeto in the AquaClear refugium and doing weekly large (>80%) water changes.
While algae/nutrient management is one thing, my simple question is simply whether that phosphate is too high for the BTAs?
