Do Softies(Leathers) grow slower in my tank because........

[Bob I]

When the subject was first proposed, I looked at my Sprung corals book to see if there were different requirement for softies, or stony corals. I see no real difference. The foods listed for almost all corals are; Light, Phytoplankton, Zooplankton, Marine Snow, Fish feces. Thus if your tank is too clean, it should affect ALL corals not just softies. I do almost no water changes, but I use Dick Boyd's Chemipure in my two larger tanks. I do add freeze dried phytoplankton often. The only real difference is the lighting. I use only PC lighting. I don't have a lot of SPS corals, but those I have seem to grow fairly well. My softies do grow quite a bit better. That is about all I can add to this discussion.
