Get your PH up it should be 8.4-8.6 in my opinion seachem reef buffer works great for that very low risk of over doseI have had it set up for about 4 months, my clownfish have bonded with it. It’s a 20 gallon I have 2 fire fish and 2 clowns and clean up crew with some Ricordia Xenia scoly and Zoas (pictures included under) with AI prime My phosphate is 0.013, salinity 1.26, 0 nitrites and ammonia, very little nitrates and ph around 7.9
