Filter not flowing...HELP!

I have an Aquaclear filter on my tank which is relatively new, maybe only a couple months old. it has been working perfectly up until recently where i noticed that it doesnt flow strong like it used to. now it just trickles. i disconnected the motor and cleaned out the propellor and got the gunk out, reassembled it, and still just trickles. its sucking water in but not strong enough??? any ideas?

Doh!! Live and learn :) Glad you solved the mystery.

Animal testing is a terrible idea; they get all nervous and give the wrong answers.

Hey Louie, I've got an Aqua Clear 70 Power Filter on my 55 gallon Barb tank, and I've had mine do the same thing...even though the suction tube wasn't plugged (LOL), and it turned out where the suction tube "meets" that "flow adjustment orifice" in the bottom of the suction sump, the tube was completely moved "away" from that orifice and flow was dramatically slower. Moved it back into place and everything was cool. Got a question for you...Does your filter overflow around where the suction tube goes into the filter? Mine does continually...must mean the pump does a higher volume than the filtration system can put through? Idk?

yeah berk i figured the same. my tank is NEVER cloudy so i assume its doing its job. turns out the reason why it got clogged was because i have a snail problem in my tank and so many of them made their way into the suction tube that they actually clogged the little slits that the water comes in! that made all the gunk build up at the same area and with the two things put together, it was like a wall that wouldnt let any water through...i cleaned it all out and took about 500 snails out of the tank this weekend so my system is running at 100%.

Maybe a prefilter sponge over the intake would help keep snails and gunk out of the assembly and intake tube. Might have to clean the sponge each week but it would I think help keep filter running at closer to potential.
I clean the impeller assembly and rinse out filter material once each week in the six tanks I currently have.When water clarity becomes slightly clouded,, I know its the filter that needs serviced.

The most important medication in your fish medicine cabinet is.. Clean water.

i thought about rinsing out the filter because i have an abundance of tiny snails in the actual sponge but ive heard that the beneficial bacteria live in the filter and it is bad for the health status of the tank so you wouldnt want to do that

Pre filter sponge goes over the uptake tube and would not affect the sponge inside your filter. The sponge inside the filter can and should be swished around in old aquarium water that you take out during water changes and stuck back in the filter. You shouldn't clean the filter material in anything but old aquarium water. Tapwater may contain chllorine which WILL kill the good bacteria with repeated cleaning in tapwater.
