Hah! If you think 2 gallons of water is heavy, try carrying a 5-gallon MiniBow filled with water to your sink... lol. WITHOUT spilling even. I actually like the Aquatic Garden feeder tanks. The large is a 2.5 gallon and they're great. We can get the HUGE tanks like that around here... the 5-gallonish ones? They're available at Petland. I'd be happy to send one to anyone if you're interested. Just PM me.
