Welcome to AA, skiingmaniac00!
krap has been a little high strung today
The answer you really want is 6x gph
, which means, you are looking for a filter that has 180 gph
. If you have very messy fish like the larger cichlids or goldfish, you want 1 gph
. Both Aqua Clear and Bio wheel filters are well liked by members of this board. Personally, I use canister filters on my tanks that are 29 gals and higher, due to the ability to put in all ceramic media or crushed coral or peat, etc.
What fish are you keeping/going to keep? Did you cycle your tank yet?
