This is the second time this happened. I have a 75gal FOWLR
I did a 20 gal
water change on Friday morning. I mixed the salt on the RODI
water for 3 days. After the water change the fish started to have rapid gill movement and then by the morning 3 died. This happened about 5mths ago. Could it be the salt? I have no idea on what to do. I still have 3 fish left, seems there rapid gill movement has slowed down. Any ideas at all?
Thanks for any help
