why such a large filter ?
forgive my asking ...
only today i was thinking that a lot of equipment may be rated for X, but isn't effective enough and larger is needed.
i have an aquaclear on my 29gallon tank, a 30 i believe, so i'm rather curious why a 70 is considered recommended for the 29 gallon ? ... is it a larger is better or is it just an adequate size for the tank ? or something else - dono what else it could be - maybe just an inferior filter type (have heard that about HOB filters)
