I am looking to buy a external filter on E-bay. One is an Eheim Prof. II 2028 canister and the other is an Eheim Prof. Wet/Dry 2227 unit. They are both about the same price. I have only had HOB filters before and not sure which would be better. I do not know the difference between a canister and a wet/dry canister filter. I will be putting it on my 90 gal tank along with my AC110 HOB filter. Any advice on which one is better??
Thanks
Amanda
