I saw these in DR.'s foster... they have a special for $75.96 you can get a eheim pro II with the two spray bar installation sets and media!(this is for model 2026+2126) they have the bigger 2028+2128 models for $90.95. I was thinking of getting one and using it for a biological canister and then packing my flu-val as primarily mechanical. Does this sound like a good idea to you guys ? I could then get rid of the bio-wheel 330 off the back of my tank? It would give me more flow.Does any one own one of these canisters? Do they work well and how often do you have to clean them? Thanks for any help!!!
