I just switched to using Seachem Prime as a dechlorinator since I'm doing a fish-in cycle in one of my tanks. However, I only do 1 or 2 gallon water changes at a time. Yesterday I used 2 drops of Seachem prime per 1 gallon because that's the dosing I found online. But to me that seems kinda weird that it would only be 2 drops. Any suggestions or tips?
