Red Sea Reefer 170. First reef tank.
Fishless cycle from late March through late April. Added 2 ocellaris, some softies, and some LPS on 4/28. 9 days later one clown has been hiding a couple days, starts swimming erratically, and dies. Other one seemed ok but not great.
Replaced the dead ocellaris, new guyseemed ok for a couple days, started staying hidden, then went missing last night.
I've done 2 25% water changes in the last week. Water is in the mixing container 24 hours with powerhead, air, and heater before going in tank. I added Seachem Prime in case the tank was cycling again but that didn't get the remaining fish out of hiding.
Parameters:
78F
1.026 sg
0 ammonia
0 nitrite
5-10 nitrate
8.3 pH
1440 Mg
400 Ca
8.7 dKH
Phosphate undedectable
Other signs are a Duncan staying closed all the time and eagle eye Zoa staying mostly closed. Other corals seem fine.
Tank is running a skimmer, carbon/gfo reactor, chaeto reactor, and UV sterilizer.
I found 2 potential issues:
1. Chaeto was dying off. Probably had too much flow and was suffocating against the top of the reactor while the bioload was too small to support it. I removed the dead chaeto.
2. Jebao UV sterilizer turns water in it black when handling it. I assume it's leeching plastic into the water. This isn't a new system so it's not a new sterilizer.
I just stopped the sterilizer and cleaned up the chaeto tonight, after a 25% WC. I'm nervous to add more livestock until I can figure out the issue.
What could be causing my issue that I haven't resized?
Do I need to do a massive WC now to get as much of the leeched plastic as possible out of the tank or is that not likely the cause?
