Hello, I am struggling to raise my ph which is at 8.0. Also my KH which is at 6.5. I have 4 small frags of Zoas. How would I be able to raise the levels. The tank has good water movement and I have 2 clowns and a six line wrasse and a coral banded shrimp. But I’m looking to add a yellow tail blenny and a pair of cardinals. I have a 37g tall and I am running a fluval c3 (Hob) and a green killing machine 9w. The tank has only been ruining close to two months. Any tips?
