I have a question regarding water conditioner and smaller water changes like 25% and 50%
I've been doing 100% changes for Paarthurnax (betta) every few days, however, I recently rescued two goldfish and they are currently in a tank that's way too small for them (working on getting something bigger today).
I plan to do a 100% change for them, but I just want to know if I'm supposed to add water conditioner (and how much) for smaller water changes like 50% and 25%
I use Aqueon and the directions say one tsp for every gallon. I think this tank is either a half gallon or a gallon (I know, waaaaay too small. I'm working on it! Haha).
