could it be the pukani. my tank is almost 3 months now. went through the diatoms then the gha and this has continued since. My clean up crew cant keep up. Im reading 0 nitrates but im assuming the algae is taking it up therefor giving me the 0 reading. my phos was 1.6 but added a reactor and got to about 0.04 but never any lower. I bleached and acid bathed the rock and let it soak for a week. i suspect the pukani has phos still leaching out.
