I was sure the sun coral wasn't a threat to my tank. More than anything just wanted to clarify on feeding. polluting the tank with excess food shouldn't be an issue(77gal with 30gal sump, mixed reef tank, lots of inverts, dragon goby, two percs, coral beauty, various softies, LPS a few SPS etc... ) but I like to spend my time time looking at my tank. A little more work is no big deal(in the grand scheme of things) but now I have a good idea on how to care for this coral properly. Thanks for the advice and info.
