I know that nothin kills the eggs which is why I am inspecting all the corals once a week for eggs whenever I do a WC. I also couldnt find a hatch out period for eggs which is why I am going for around 4 months to make sure. I am also waiting for kelly to get me in some fish that eat them for some natural defence.
But if I decide to take this other job the tank with be turned into a FOWLR system and all the corals will either be sold/given away or tossed in the trash
