I haven't experienced any of the bad symptoms you've discribed .I assume you are using the Ultra Lith media ( zeolite rock ) in some sort of reactor. I myself use the Ultra Bio in the 50 ml container so I use drops daily instead of the ampule .The corals that are affected , are they in the location of your dosing? I add mine a drop at a time in front of a Koralia powerhead to dispurse it at night before I turn the lights off. Did you use a phosphate remover before starting the system? I have a hang on refugium with minimum chaeto in it. In a previous post there was a RC link to a conflict with a fuge. Maybe take a look at the link. You could try " cutting " the additives with salt water from your tank and then dose that back into the tank. Is your skimmer working well? Mine was pulling out more than normal for the first while. Softies and mushrooms like nutrient rich water. Feed well ,skim well.
