I was reading my Natural Reef Aquariums Book and it says that having Caulerpa in a system with SPS Corals is not a good idea, the SPS corals do not like the chemicals the caulerpa gives off. Is this true? I have been having problems with my SPS corals dying off some then growning, then dying off again. I know the caulerpa uses alot of calcium but I got a larger CA Reactor to help this problem. I have alot of caulerpa in the sumps and was thinking of removing caulerpa and just running a very small amount as part of my filter system. Any help would be great, everything is in check in the tank chemical wise.
