Probably have the best luck getting a new one from Petco or the likes of. I never understood why a 5.5 gallon tank is $14.99 new and the 10s are only $12.99. Seems like Petco is keeping their $1/gallon sale going so the 10s are only $10, but 5.5s are not included in the sale. I made a 20 long sump this weekend so I know they still have tanks on sale.

I've thought about sumping my 29 so I can run macro easier but didn't think the tank would fit in my stand. You've given me hope I can still do it with a 5.5. I'm interested in how it works for you. What kind of stand do you have?
