I bought $1500 worth of chalices from Richard (Cornbread) and they all either died within hours or are dying. I bought 2 more and they just died as soon as I put them in the tank. My other stuff is growing and I have two chalices from other people but Richards don't make it which is adman shame because his are the best anywhere. I have 3 actinic an 1 actinic day on the tank and I put them on the bottom. The only filtration I have is a skimmer rated for 250gal on a 100 gal tank. I have other stuff growing like crazy including acros on top and other LPSs that are doing well. Richard said use only actenic but I tried that and they still died. Can you guys help me out? Chalices are my favorite but I cant just keep killing expensive frags over and over.
