I have a 125 gallon (6' long tank). From what I am reading you guys are recommending a filter that can filter 10x the tank amount in an hour? With a tank my size filtering that much would require something like a garden hose on full blast to pump enough water through a filter 10x per hour. Right now I have a Eheim 2217 canister filter which looks like it filters the tank once per hour or about that? So I can understand everything correctly, what is the benefit of filtering so much in so little time? I believe you that it is nice to have, just trying to understand it all. And does that hold true for such a big tank like mine? What kind of filter would I get? It would have to be one heck of a filter! Since I have added CO2 2 months ago and finally dosing with ferts my plants have taken a great turn for the better. I want to make sure I keep things rolling strong though and if my filter is low I want to know what I can do about it. Thanks!!!
