Hi! I currently have a 50 gallon tank and would like to hear your recommendations on canisters. I've been considering the Eheim Classic, but also see many people enjoying the Rena XP3. What other canisters would you recommend?
Are there any sites that I can look at sell canisters? There was another thread mentioning the XP3 for sale at $120, but that site adjusted the price.
Correct me if I'm wrong, but I need a filter that is at least 3x the size of my tank AND 5x GPH circulation?
