I currently have a mixed reef that has been doing well for some time now. No new additions. I have two separate sump sections; one which houses the skimmer, and another before the return. I removed the one before the return to fix a baffle that had come undone, and temporarily replaced it with another tank to serve the same purpose in it's absence. When I returned the old tank back into operation, I noticed over the week that many of my corals seem to be slowly deteriorating - SPS is starting to fade in colors, and I no longer see little polyps. Monticaps have appeared to stop growing and starting to recede in certain areas. frogspawn doesn't open completely until halides are on. Torches, zoas, and bubble coral not expanding as they used to.
All water parameters are perfect - temp, salinity, nitrates, ammonia, phosphate, calcium, alkalinity. I've heard of this happening to others, and it was stray voltage. So I checked that, and that was 0V (is that even possible??). I double checked the connection to make sure it was not an error.
What are other possibilities that I may not be considering?? Could this have been because I added a new baffle to the sump? I used 100% silicone, and allowed it to dry thoroughly.
help!!
