I bought a 55 gallon at petco $ per gallon sale also. can't beat that.I wish they did that sale with some larger tanks though,
also craislist is great. I got a 38 column with heater. gravel, food, meds, fish , live plants and biowheel for 150.00. I only paid that much for it because it was adverised as a 55 otherwise I would not have got it
and a 55 gallon with a decent stand, 3 filters, gravel. 2 backgrounds, a light, liguid test kit, food, book, and just a bunch of stuff for 100$
Otherthen the pet co sale I can't imagine me ever buying new.
