The second unit has particle board shelves. Particle board and water? Not a really good combination.
The second unit won't hold the weight anyway. I put a 29 in one of the lower shelves and had to get pieces of 2 x 6 and screw them in the bottom. Also a piece of all tread to prevent the metal bracket from twisting. They only work for small tanks. 5 gals and 2.5 gal.The second unit has particle board shelves. Particle board and water?

Thanks Rachel, I remember you talking about them before.. I plan to get an extra for backup as you just never know when one will fail.
