Yup, this would be ideal and preferred for sure! You can get the big 33g totes for heap(ish) but then you are going to have to buy a few of them, plus you will have a bunch of them littering your room with water and you would want to keep them all heated because the heat will drop in them fast! That would be the disadvantage I'd see in this case..

You know what, if I remove all the rock from my tank, I will probably only have about 60-70 gallons of water. I was assuming that I would have to remove 130 gallons from my tank because that is what size it is. Now I just have to find a 60-70 gallon container or maybe I'll just go with the previous idea
