Wtb tank filter

[tran901]

I got a 27g cube and need a filter for it. I have a cascade that I can't get to work. So I need something that will work. So I don't have to drill it

Thanks!

Old and reliable is either a Tunze external or a Magnum 350. Both are canister type filters, if you didnt' want to go the HOB (hang on back) style of skimmers.
