A most excellent idea. Two tanks underneath with the top one for a tank holding change water. I remember your recent post of just that thing. A most excellent idea.Get a triple tier stand and you can have 3 tanks where the tank on the floor is situated.
You're reading my mind Buddy. All empires have small beginnings.You could put a 5 gallon on the corner table. And maybe a tank on your kitchen counter, and one in your bathroom, and so on and so on and so on. Methinks you will soon have a bad case of MTS.
