I have had LPS in the past but had a crash a few years back that wiped my tank out, Kept a fiowlr except for GSP can't kill that stuff, I have begun to get back into reefing and need a little advice. I have never kept frogspawn or hammers, looks like they like low to medium flow and low position i the tank. A friend recently gave me a large branch of hammers they look good but yesterday they began excreting slime, I know that is how they catch food and get rid of waste but will they stay closed for a time after this occurs? What, how and how often do you guys feed your hammers and frogspawn?
