I came back to find one of my ac is a bit noisey. I cleaned it out but it did not fix the problem. Works fine just noisey in the motor. ANy ideas?

It is about 1 year old.

It probably needs a new impeller since this is the only moving part. Theyre around $5-$10.

there's an ac300 running on one of my dad's tanks that my late mom bought sometime prior to ninety-five--it's still going with no problems.

Rudy, Is it a sand substrate tank. If so Take the impellor out of the magnet drive and force water thru the little hole (high pressure), then put the mag drive under the tap and flush it with hot water. Then put the impellor back in and submerge it about 75% into a sink full of water, then turn it on. Careful the AC500 can pull your hand under. Repeat if necessary, sometime it takes quite a few flushing to get the thing clean..

Fitch. I like your idea, but can I submerge the entire motor? Or do I turn it upside down?

Q-Tips and turkey basters are great for cleaning out the inside of impeller motors 8)

Ya, sorry meant to say invert it, that is why it is only 75%... yes you can submerse them completely, but be careful it the seal isn't 100% you have yourself a surefired hang-over cure. :idea:

While it runs upside down it is flushing the sand out. But the shaft and the impellor still sometimes have sand, I usually just put it tight to the tap seal it with my thumb and index finger then turn on the water. Yes I get wet, but I don't care.

Another tip...

Put your intake further away from your airstone. They carry alot of sand into the water column, and then the filter sucks it in. You would be amazed at how much minute sand gets cycling around in your tank.

Or avoid any direct Power head flows towards short sides, ie don't point a power head directly to the front of your tank. Set it up so that it ricoches... think 8 ball off 2 and in the far corner.

think it'll work for whispers, too?

If you can remove the mag drive, and remove the impellor I don't see why not. Wouldn't know though, I don't have any whispers.

is the mag drive the power pack/energizer thingy?

Yep, it is just an electromagnetic coil.

I have an aquaclear 300, and the impeller is quite noisy. Little to my surprise, when I took it out of the filter, the impeller has 6 little turbine blades, mine has 5, and so I went to the store, took out the little manual from the box, and it is part A-636. I will call hagen or email them to send me a new one soon
