I'm thinking about making a diy canister filter for my 10 gallon fw community tank. If I decide to do it I will use 2 powerheads, the type of tubing that is used for gravel vacuums, a 5 gal bucket, a smaller bucket, and a bunch of filter media. To do this I will drill a hole in the bottom of the smaller bucket and somehow attach it to an onside side of the big bucket. I will have one powerheqd pump water down from da tank to the small bucket which will have a bunch of filter media in it. The water will trickle down through the hole and pool into the big bucket and then another power head will pump clean filtered water back up to the tank. Tell me what you think.
