i have a smaller tank that i minght want to make SW if my brother gets a bigger tank for graduation, but he wants to use the 15 to put jewel cichlids in. and my mom will not alow anymore tanks in her house, lol.
the think with my tank is its a pentagon, and its not rectangular or square like the ones on that site. So I guess Ill stay away from SW
My 5 gallon is a weird shape kind of pentagonish I don't think it would make much of a difference as long as you found a piece of LR that fit or even a few good sized chunks of LR rubble. I would love the challange of doing a nano this size. I say go for it at worst it will be a learning experiance and the cost shouldn't be very much for a 1 gallon tank , I would think that you wouldn't need a heater ,if you kept it in an area that didn't catch drafts the heat from the light should be enough. The biggest problem might be circulation , but my 5 gallon does just fine with just the filter for circulation.

This place sells great LR rubble and LR grunge by the pound the shipping is very reasonable and the stuff always comes in two days from the day shipped( the grunge is on the Live Sand page) a few pounda of the grunge and a pound or two of the LR rubble should be perfict for the little tank. ( The last batch of LR rubble I got from them was loaded with small fan worms !!!)
