okay, I will be the first to admit, I was an idiot when doing my research. Gotta say there is ALOT of conflicting info out there. That being said...i need to start planning out a plywood tank, something simple and effective, with reasonable dimensions. If you read my introductory post http://www.monsterfishkeepers.com/f...the-RIGHT-info-a-bit-late-but-glad-I-found-it it explains it all....but the short story is that I have 3 ID sharks and a banded hifin sucker...all around 2-3" in size...and growing. Anyone out there have suggestions on size? filtration? I have never tried to conquer something this size, and people around here only suggest that I would be "...unable to do that myself..." and to "...leave it to the pro's..." which more or less tells me that they don't want to give up trade secrets, and would rather I dump money in their pockets, which I refuse to do, especially if I can do this myself. Any and all thoughts welcome.
