I was told by a fellow reefer that I should try dosing it so I gave it a try. Again I know, it was stupid on my part for just following the crowd and I should have done some research but the local fish store told me the same thing (not disclosing the store name). I called my brother this morning and told him to stop the dosing and he said ok. I will have him do a water change also. Do you think this is whats cauing the brian coral to die?
