Help AC filter not working - Aquarium Advice

dvanv · 07-03-2009, 07:52 PM

I have a 29 gallon tank with a AC50 which has been set up for about five months. The setup and filter were new. I went out of town and when I got back the filter was humming but not working. I took it all apart and couldn't find anything that would make it stop working. I replaced the motor unit and it worked but now that unit is humming and not working.
Has anyone had a problem like this? Do I need to replace the entire unit?

Have you tried to fill it with water as it's "humming"? Sometimes mine will lose prime after being off and need to be filled. Did you have a power outage while you were gone?

I tried to fill it with water while it was humming but nothing happened more than the humming. No power outage I have asked the neighbors to double check and nothing.

Did you check to make sure a pebble or something isn't jamming the impeller?

Nothing restricting the impeller. I have pool sand in the tank. I think I am running out of choices.

Does the impeller turn? Have you tried to reseat it?

Do you mean reseat it by taking it out and putting it back in? I did that a couple of times. The impeller does turn.

I'm honestly stumped. Sorry. If you figure it out, please let us know. I'm really curious now!

Maybe the impeller is somehow bad?

I think if I get this running it will be an accident. I just don't want to go and buy something right now. I will keep trying and see what happens. Thanks for all of the ideas.
