I am looking in to going to a 6' tank, poss from 150 to 210. but I am not sure what type of filtration to use. I currently have three tanks 90g african tank with an AC110 and fluval 203. A 75g south american tank with a penguin 330 hob, and a 55g babie tank with an AC 70. Now I am not sure, multiple HOB filters or a good canister filter. or a combo of the two. any help or insight would be good. the 6' tank will be a cichlid tank not planted.
