Lija,

Nice setup! You have a lot of tanks going! Now I don't feel like I am going to cray lol.

I have one of the smaller shelves down there right now I use to hold feeder insect cultures, left over Hardwoods, and misc tank supplies. Though I think In the redesign I am going to repurpose it for future tadpole rearing/growout tanks. I got an industrial strength self back in Feb that most of my tanks are on. It can hold something like 3000lbs a shelf of something ridiculous lol. 2 of my tanks are against another wall on a cinderblock + MDF make shift tank stand (it is what my 40B use to sit on when it was horizontal, but can hold 2x 18" tanks with vertical tanks on it.

I think I want to get some selves to move the 2 tanks that are on the makeshift stand so I can reclaim that wall space for another rack that can hold 4 - 6 more tanks.... I wish the ceiling in my basement was higher :/
