Hello all and thank you for all the information presented here. I have a Biocube 16 and trying saltwater. I'm 3 months in now. I have lost already 2 clowns, 5 of my CUC. I had nitrite problems, now that seems under control but the ph got too high and took put my CUC. Testing the water with saltwater master test kit, and today, even after water changes, start biobloom stuff, everything is out of whack. Not sure what I'm doing wrong. Heading for another water change to clean up some mold looking stuff left from the already wafers. Any suggestions would be great.
