We have a standard 125 with a 45 gallon sump. Our tank was doing beautifully (was about 9 months running at the time) with the exception of a very bad outbreak of red cyano that was starting to cover and kill corals. I went into the hospital on December 14th and came home January 28th to a cyano free tank but corals that were doing very poorly. While I was in the hospital my husband used chemi clean on the cyano. He followed the directions precisely and we’ve done many large water changes since. All my parameters are very stable. Every time I test pH, dKH, salinity, and electrolytes are all tight (meaning very little if any variation in results). Temp is kept at 78, NO3 2-5 and PO4 .05. Almost all my SOS died overnight, my zoas look pathetic and my once out of control plays are almost all gone. Even my once out of co from green hairy mushrooms are looking sad. I have sold the tank and it will be torn down and go to its new owners in May 1 but I want to know what happened. I am planning on moving one very large rock that has a beautiful RBTA to a 40 breeder and getting a few more nems and some clowns (Can no longer handle the big mixed reef due to my serious medical issues) but worried about the rock being bad somehow. I really have no idea what happened. I did change from Noopsyche lights to T5’s with an LED strip but these problems s started long before the lighting changes. Any insight would be appreciated. The 40 breeder is getting all new arag alive sand, fresh water and several rocks from my 125.
Thanks!
Thanks!
