I have a biocube 14 up and running for over 6 years and the last year I've had problems with the oxygen level in the tank and keeping fish in there. Very low oxygen I have the lid propped open with the feeding tray also now. I am having issues with my pH being too low below 8 and currently have a lot of coral in the tank that don't look really bad some of the hammers are huge but my KH is at 7.3 and my calcium stays at 390 Any suggestions in any of this information?
