Did you remember to dechlorinate the water?
Yep, every time, especially since our water does sometimes have a chlorine smell. Using Seachem Prime. It is a little hard to dose however, since it calls for 5ml for 50 gallons, and my water changes are only about 1.5-5 gallons. Might be averaging on the high dose side since so little is needed.
Good thing you came here to find answers, so welcome.
