Both of my clowns and possibly my coral beauty(not sure if its a bubble or something since theirs only one spot on him.) have ich. I don't have space in my room for a qt and i don't have the money for one either since i'm 17 with no job lol. But how do i go about doing a freshwater dip? All i know is to dechlorinate the water, and to get the water to the same temperature as the saltwater tank. Is there any thing else i should do?
