OK - here goes my first attempt to build a plywood setup.

My plan is to build 2 shallow plywood tanks cradled in a fame and stacked one above the other. These are to serve as hospital / growout tanks for my planned massive tank, and a practice run for me. I'm thinking of something like this:

I'd like some feedback on my frame design. The brown/grey are the heavier timbers, pink are the smaller timbers and yellow is the plywood. The set up is about 4' 6" long, 2' wide and 5' 10" high

I'm planning to use plywood and liquid rubber for sealing the tank. Acrylic for the windows.

This is how I plan to set up the frame. I was thinking of the large timbers being 7cm x 3.3cm (3" by 1.5") and the smaller ones half that size. The whole set up is glued and screwed together.

"I personally would build the tanks then build the stand"

Or at least keep the top tank seperate (just sits on top) and consider the lower tank as part of the stand. That will make it a lot easier to construct, water proof and of course move...

Looks plenty strong enough tho.
 
I think you guys are right. I'll try to re-design it to have 3 sections that interlock. I'll have a stand, separate middle tank and separate upper tank.

Working on my sump at the moment - progress is good. Will start painting next week.
 
Way too cute!

I would use this for your frame. Its much stronger and you will use ONE less piece of wood each tank [less money :headbang2]

A - Screwing these pieces together [the whole length] will create the stability needed. Otherwise they will separate under the pressure. Wood in its horizontal orientation is more susceptible to bowing than in the vertical orientation. Together they become very strong and will resist pressures from any direction.

B - Adding the middle beam will help distribute the weight and you probably done need it but i would add it for piece of mind

I can't quite make out how the beams (A) are laid out mate.
 
i hope this is clearer. but it's a L .. a vertical on top of a horizontal.
