I lost a lot of CO2 with the surface disturbance that filter created. Unfortunately I was a few gallons over the Fluval 2 filter so I picked up the Fluval 3. it is very large for a 26 gal tank but I can imagine you wouldn't have a problem with the 34 Gal that it is rated for. This filter does a nice job of creating a current in my tank (my Tiger Barbs even seem to enjoy it, letting themselves get pushed across the tank only to hop out of the current and back in near the source.) I've only been using it for about a week so I can't say how well it cleans the tank. But it is an amazing upgrade for a planted tank over the last filter in retaining CO2 in the tank and creating a nice current. And it's amazingly quiet. (now if only I can get my light fixture to quite down :D )   1     2   Non User
