I am buyng a 125 gallon tank and wanting information on filtration for it. Me and my wife are pretty sure we are going the african cichlid route and I am getting all kinds of mixed reviews on how to filter such a tank. I want to know from tank owners that have just canister filters running there tank with no problems. I want to get away from the hang ons and just have the cleaner look. As of now I have not purchased any filters but everyone wants me to run two emperor 400 and maybe a canister in the future for clarity??? I am new at this i repeat so please explain for me why people keep wanting me to run the hang ons and not run just a canister style? If it can be done please let me know what size and what brand. Thank you in advance. Chris Derrick
