I currently have a 10 gallon freshwater tank but I'm looking to upgrade to a 29 gallon freshwater tank within the year. I want to get a new filter and want to buy one with the upcoming 29 gallon tank in mind. The two filters that I've heard good things about are the AquaClear 50 and the Marineland BioWheel 200. Any recommendations over which one is better and why? OR if you would recommend something completely different. I'd like to stay under $50. Also, just to make sure... will either of these filters be too much for the 10 gallon? Thank you!!
