Just curious, is it bad for any certain types of fish if you are running a powerhead 24 hours a day. The reason I ask is, I have a 802 powerhead in my 75 gallon. I have a flowerhorn,parrot,datinoid,6 giant danios and a green spotted puffer in the tank. The puffer seems to sit in the corner where the current is weak and doen't move much until feeding time.When I turn the powerhead off the puffer swims around more. The other fish don't seem to mind but it made me wonder if the current might be too much for them 24/7 and stressing them out at all?
Should I have the powerhead on a timer?
