rena filstar filter

Question
I have 3 aquariums all using Rena Canister Filters. I am having a problem with 1 of the XP3 filters. There is a loud humming sound when it is plugged in. It filters the water fine but the sound it makes has me concerned. I have cleaned the little wheel inside the top but the problem is still there.
Also, do you know where I could buy a large quanity of the suction cups. I have repaced them numerous times but are quite expensive in packs 6.
Thanks

Answer
Hello,

You can buy suction cups at home depot, ace hardware, and many more hardware stores. And for the filter it sounds like you lost the rubber stopper in the motor at the motor end of the wand. If this happens the filter well still operate but there well be a loud humming sound coming from the tank. This is a little bit hard to replace. I have the same problem with my canister filter and still have not found the replacement parts. I well tell you if I find some though.
