lol I have the 500(110) a new one for extra bio filtration on my 100 gallon cichlid tank I love them, but its a pain to clean all my filters all the time!! haha but I guess thats part of the joy!

Lol I agree Brett... I hate the new names. They've been out for a few years like that and I always confuse new people when Im chatting about them lol.

Haha pretty much. Cichlids poop... you probably have lots of them. Its the way it is lol.

Steve has a Devon Rex...trouble makers!

If you cut off half the fins on the impeller for the AC110 it will slow the flow down so it would work better on a small tank.

Haha yeah I tried that its really tough to balance.

How big is the display tank?

20 gallons

AC 110s really move water. In your experience, what sized tank would this impeller modification work on? Is a 10 too small?

TIA :)

Hmmm, fluval 105/205? Im running a 205 on my 29 and couldnt be happier. Its honestly the best filter Ive ever run. When I chum the water I cut flow on the fluval and let the circulation pump be the cobra commander for an hour or so. Then I throw the flow back on full. I just love the features on them. People say they feel cheap but I like them. Maybe look into the new marine land canisters. They supposedly have the highest flow of canisters in their class

I am afraid to wreck another impeller this way. Lol and yes, they move a ton of water, what is it, 500gph?

Something in that range yeah. The price tag isnt too horrifying on them either. I think they're worth a second look. Honestly with my fluval 205, I took out one of the activated carbon bags and replaced it with with a bag of chemi-pure. The next morning my jaw dropped at the results. Of course at that time I was running a cascade 600 (internal canister). So any filter is probably a jaw dropper. All I can say is from personal experience is the -05 series are real champs.
