Hello everyone, I have given up on the new generation of Fluval canisters and plan to switch to Ehiems. I will be putting the Eheims on 150 gl tanks filled with African or Cent. American cichlids. I'd like advice on what model(s) would work best under these conditons. Would one of the recommended 160 gl filters do the job or go with two of the smaller versions? Thanks in advance, Ray
