I read somewhere that if you start a tank off with soft corals, that when you decide to start adding hard corals, the chemicals released by the softies will make it more difficult for the hard corals to get going. The article said it would be best to do an all hard coral tank, or an all softy tank. And in the wild you rarely see them mixed. There will be one whole section of a reef with all softies, or one whole section with all sps, but not mixed.
Anyone else heard this?
