I guess 2 degrees. Hes had quite a bit of stress today. I’ll just leave him be. He is great right now. He is hiding behind his favorite plant. he stuck his head under the sponge filter for a while. The tank is crystal clear. The Fx5 is so strong. I don't think Sparky was expecting that. He swam into the stream and almost got knocked against the glass. He never went into the stream again. the thing is, the filter outtake is right next to the HOB and sponge filter. there is an insane amount of flow in that corner of the tank.You could probably get away with doing that faster. If I need to make a temp change, I will just turn the heater right to that, probably not recommended but I’ve never had any fish show temp change problems. Same with if I accidentally fill a tank too hot or cold on w/c day.
