Does it look ok? Kinda looks more brown today than last week. I have it middle-high in tank near powerhead but not directly in front for Mod flow.

Well i guess it's my fault. I should be like Montipora and disclaim that you have to have proper lighting for corals i sell. I know that green slimers are hardy as hell, but i've never been a believer of sps corals under anything but MH. It definately looks browned out. sorry.Chiefmcfuz said:![]()

:scratch: I thought that zoox is naturally brown and will multiply rapidly (brown coral) under 2 conditions: (1) when there's too much light, the zoox's color begins to overshadow the coral's natural color. In this case, the coral may expel the growing zoox population to prevent it from overloading the coral with "energy" or (2) when there's too many nutrients feeding the zoox in the absence of sufficient light, the zoox population will grow, again hiding the coral's true color.masterswimmer said:What is happening is the symbiotic algae, zooxanthelae (sp?) is being starved for light. The way corals get their color is from the zoox coloring up from the light. When you don't have sufficient light, the zoox don't retain their color, but the coral can still live, not happily though.

I guess I better go research some of the threads we have in the Advanced Forum on this topic.
