I've only had experience with HOB filters and my next tank might have a different filtration unit such as a canister filter. Could you recommend a brand and model since I don't know anything about them? Also, if you could list some pros and cons about them, I'd appreciate that. Thanks so much.
edit: oh I forgot to add that it has to be inexpensive.
