My 5gal has a TopFin10 HOB and I'm afraid the outflow is waaaaaaaaay too powerful for my little betta. I had a whisper in tank in there before but he kept swimming into the filter and sleeping (he may have liked it, I did not). Plus it didn't do squat as a filter (came with the tank).
Anyways, how do I slow down the flow? These filters do not have an adjuster.
Maybe a piece of sponge just before the outtake?
