In my 10 gal I have made and am using the appropriate baffles, the intake and outtake. But the filter started running good, then slowed until it was barely a trickle. I tried everything until i pulled off the pantyhose and unclicked the second link of the intake, put it back, and turned the filter on. It started off good again, and did the same thing. I don't know what to do now, each time the filter slows Evander sits in the water bottle baffle and flares at me when i try to mave him to fix the filter.
