Undergravel filter


Recommended Posts

Only chemical filtration needs to be turned off. Since your filter media is the gravel in your aquarium and it is only performing biological filtration you should leave your undergravel filter running just like it is. I would not recommend turning the powerheads off as that will not be good for the beneficial bacteria in your gravel.
