I'm stumped with my tank. The problem I'm having is all my zoas,clove polyps etc stay closed. Frogspawn,hammers and torch are not fully extending either. They look great for a few days after I get them but then close up. Some open but most stay closed. I always dip everything before it goes into my tank. All fish in inverts are doing awesome. I have tested every parameter over and over again. They all fall in Randy's range. Alk=9 Cal=420 Mag=1350 Ph=8.2 Ammonia=0 Nitrite=0 Nitrate=2 Po4=.02 Temp=77. My tank is a Red Sea Reefer 250. I'm running Ecotech xr15 G4 lights(35%),mp10 power heads,Vectra return and reef octopus skimmer. My husbandry is very good. I do a 10% water change every other week. I just recently put a bag of carbon(6 tbsb)in my sump to see if that would help. I don't know what is irritating them. My water comes from a well here in Florida. It first runs through a 2.0 cu ft centaur carbon tank then a 2.0 cu ft softener. After that in my house it goes through a brs 4 stage rodi unit. I'm using brightwell salt. I'm hoping someone has a idea what I'm missing. My next step is to get a triton test. My last tank did the same thing. I had to tear it down do to a remodel. This current tank is completely new along with all the equipment.
