From what I've read on the site, you can never have too much filter. Right now, my pond is a small preformed pond around 60 gallons. I plan (once I get a job and $$) to dig out the raised planter it is in and put a liner pond in it. That pond will be 650 gallons or so (I know, still a small pond, but, that's what hubby will let me get away with). Anyway, I have a 55 gallon drum and all the PVC fittings etc... to make a DOC or Skippy style bio-filter. Would that be too much for my current pond, since it is almost the same size? Or, does it even matter? I'd like to build one that will be big enough for the larger pond so I don't need to do it twice.
Thanks
