I have softies, mainly zoas, mushrooms, and xenia....also have a torch coral with 3 heads....other than the trace elements that are in the salt I use and Kent phyto and a little bit of iodine, should I be adding anything else? I have always had HEAVY coralline growth and glass algae so I definitely have nutrients in the water. Should I be adding anything else specifically? Zooplankton or anything else? Also how much phyto should I be adding and how often? Thanks
