So I thought I got a real good deal, and I still feel I did pretty well. I just did the math and realized that my 450 gallon tank that I purchased off craigslist is really 240 gallons. It is still huge (96"X24"X24") and now that I purchased filtration for what was supposed to be a 450 gallon tank, I will never have to ask myself if I have enough filtration. Right now I am ok, but seems I will have a high stock capacity when my fish grow. I hear a lot from both sides, I see video of some with very large fish crammed in aquariums. And I run into advising a 700 gallon for pacu. Anyways, what are your thoughts?
