I dosed fluconazole for gha in my mixed reef 22 days ago. I barely had any gha in my display, but my overflows and sump were teaming with it. I still have a tiny amount left, but it's far less and comes off easily.
I've been waiting for a bump in N03 & P04, but have yet to see one. I've tested zero for both since a month or so after I started the system 1.5yrs ago. But I had a major gha problem until approx 6 months ago. My fish are fat and my system is borderline over stocked. I do run phosguard and have a small deep sand bed in my sump. Considering the amount of gha I used to have, and the fat bellys on my fish, I know I have to have n03 and p04. I can't believe the phosguard, dsb, and corals are consuming enough where I can't test for either.
Any thoughts?
220gal, +approx 30gal in the sump.
