First get 3 containers that can hold half a gallon each. First container I dipped the coral in coral Rx by following the bottle dosage recommendations (10 min). After move the frag to plain saltwater for a recovery rinse (10 to 15 min). Finally 25 ml of Dr tims eco balance bacteria in the last container. Ideally you want a lightly cloudy water solution, if needed I wouldn't be worried about adding more. Doesn't seem to stress the coral (15 min). Directly return to the tank no rinse needed. I then dump the bacteria solution water in the tank as to not waist the product. The idea is to force a concentrated amount to make contact with the coral. In theory, the probiotic bacterium enter the coral to strengthen and eliminate bad strains of bacteria destroying the coral. If I ever observe stn in my tank this is what I will do from now on every time. I didn't lose a single colony of the 4 total, other methods in the past I was unable to stop the stn.
