Hi, I have two of those filters on my 35 gallon and I love them. They don't have room for bio-media though. Here is a link on how to modify them if you want. 200 or 250 should be fine. On my two filters I put a little piece of filter padding under the outflow area and it really helps with subduing the current.would that do the trick ??? i have heard good things about these filters and it is 200 GPH.
I would do an AquaClear, personally. That way you have lots of room for media. I would get a 70 and a 20 or 30. Or you can do what I did for my 29 gallon and buy one of these...would that do the trick ??? i have heard good things about these filters and it is 200 GPH.
