We just suffered some minor losses after resealing an old 20g with GE 1, used it in the past just fine. Over two days it damaged some soft corals and killed a small wrasse. CUC seemed fine so I threw the into a larger system.
What can I now do with the rock remaining? Can this be rinsed off in a saltwater bucket and thrown into the sump on our larger system or will the rock absorb the chemicals and release them again? Almost leaning towards bleaching the rock and starting over to be safe.
