I woke up to half my fish lethargic and sitting on the sand bed but all inverts and corals are doing fine. I did a quick 50% water change that had no effect. Any ideas on what could be causing the sudden issues?
Salinity is right at 35, pH is at 7.9, ammonia and nitrite are still zero, nitrate at 16 and all other parameters seem to be in line. I did make a few changes this past weekend but am not sure it’s those since the fish were fine for 3 days prior.
On Saturday I stopped dosing Polyplab Medic, performed a 25% WC and added carbon. I did not start the skimmer as it instantly overflowed, so I did another 25% on Monday. On Saturday, I also installed my UV sterilizer with braided poly hose, set up my auto water change with versa pumps, connected a buddie booster RODI pump to the ATO with RODI tubing from BRS. All was flushed prior to hooking up so not sure if these would cause it.
The only thing I did yesterday was glue pvc to eventually hard plumb the UV but this was done at the other end of the basement, approximately 70 feet away with a window open. Would the PVC glue emit enough VOCs as it dries to cause trouble with the fish 70ft away and not the corals/inverts?
