I am looking to start raising species of softies will grow in 68'-72'. Still in the research stage. I was advised that some of the deep water zoas can handle 72'-74'. Some acans may also be a option. I have a large amount of effluent from my fry tanks and am researching using this for coral propagation since it is full of pods and BBS. I could warm the water, however I want to establish corals that I can ultimately place in my adult tanks. Any suggestions are welcome, along with those that say I am totally out of my mind.
