fluval 2

I have a fluval plus 3 on a 80 litre with guppies and danios and it does a decent job, so yeah thay are pretty good for a internal how big is your tank i have recently bought a bigger tank and got a cannister and now i wish i had a small cannister for my 80 litre but o well, but yeah the fluval plus range seems very good for the price i have a spraybar on my as it is bigger then the recommended 2 plus for my tank. sorry about the rambling HTH jimmy
 
I have decided to go w/ the 3+ just because I like more filtration than needed, my tank is going to be a 20 long. I have a eheim 2217 on my 75g and love it, but am not going to buy an external canister for a 20. My next choice would be a power filter but since I am going to put it in a planted tank I can not use activated carbon. Soooo that leads me to this choice s ince I hate UGFs. Does it distrub the water surface well? I am not going to have a large bioload. Just two german blues, a school of cardinal or neons, 3 panda corys and a few ottos so I dont need anything to powerful
