Hello folks,
I seem to be having a problem (?) with the HOB filter in our 20 gallon. It's an aquaclear 70, with sponge and biomax in the basket. There is also a sponge on the intake, as we have small fish.
I've noticed that the output has slowed to more of a trickle than a nice full fall. I checked the fit of the uptake and it seems to be in properly, I've cleaned the impeller, and removing the sponge on the uptake doesn't help. The only thing that seems to temporarily remedy the situation is pushing down on the basket (which leads me to think that I may have too much media in there?). Unfortunately, I can't get it to stay in a position to allow for better water flow.
Any ideas as to what the problem could be? Is it detrimental to the fish to not have a complete flow/current coming from the output?
Thanks in advance.
