AquaClear 100 Flow Problem
I have an AquaClear 110 that's only about two months old. For the last two weeks, the flow has been variable. I can hear it running strong and loud one minute, then it dies down quite a bit and runs weak and quiet the next minute. It seems to go through this cycle every 30 seconds or so. The intake is clear, and I swabbed out the motor with a Q-tip (even though the inside was clean and without gunk). I've also played with the intake tube's adjustable flow, but that doesn't help with the problem. Can anyone tell me what might be the problem and a possible solution?
Thanks in advance,
