How big is the tank? Is it going to be filled with water? If it is I would use some type of framing not just plywood.
Ah, you got some experience with this. Cool. I'm a little fuzzy on the 2×2 idea. Is that running the length up the sides and back? Can't do that, sump won't fit. My research tells me that the main idea is prevent racking from side to side. The stand is all dry fit right now and no b screws in the back panel and it's solid when pushing on one side. I see no flex on the other.I was thinking the same thing. When I used to build tanks for buddy that has a reef tank business I always built a frame of 2×4. The structural part was somewhat separate from the pretty part.
Consider adding something in the corners. I know tank guys love space for pumps and sump .
Even a 2×2 gorilla glued in the corners is better then nothing.
Good Luck

I can show you any number of stands built similarly that hold larger tanks than mine.well your looking at about 750-800lbs my friend. as in the movie jaws when they see the shark and says,your gonna need a bigger boat !!! well your gonna need a hell of a lot stronger stand my friend. what your making is a huge accident waiting to happen.id say scrap what youve done and re engineer. you need a strong frame for that much water plus weight of the tank.back to the drawing board.

not in my house you wont.if your gonna rely on plywood and pocket screws alone,good luck. please post some pic's of those stands your talking about.well your looking at about 750-800lbs my friend. as in the movie jaws when they see the shark and says,your gonna need a bigger boat !!! well your gonna need a hell of a lot stronger stand my friend. what your making is a huge accident waiting to happen.id say scrap what youve done and re engineer. you need a strong frame for that much water plus weight of the tank.back to the drawing board.

Here is an example of a commercial stand, made with MDF.well your looking at about 750-800lbs my friend. as in the movie jaws when they see the shark and says,your gonna need a bigger boat !!! well your gonna need a hell of a lot stronger stand my friend. what your making is a huge accident waiting to happen.id say scrap what youve done and re engineer. you need a strong frame for that much water plus weight of the tank.back to the drawing board.

Thanks Nathan. If you look at 5th pic that shows the front top panel, I mentioned doing your idea of doubling up a stretcher behind that and it would be directly under the top. Good idea!I think that the plywood sides and back will be pretty strong, though the front corners need more support, IMO. If you think about it, four 2×4s in the corners are less wood than the 3 sides of plywood as long as the joinery prevents them from bowing out our racking. The dowels and pocket screws (and glue) on the back panel will prevent that. My concern is with the top and front apron, stretcher or whatever that header is called. I think that doubling it up makes it strong enough but I would want support under it, not just attached to the front. I probably would have put it under the top, like the apron of a table and if you add a vertical strip under each end on the front, that adds more support and also makes the front corners stronger (attach them to the sides with pocket screws). I built plywood legs for my "assembly/outfeed table (see below) and the legs are plenty strong. I have had 400-500 lbs on it and it seemed rock solid. It also would not hurt to put a piece under the top in the middle connecting the front header to the back. My 2-cents.

Racking or sagging?That particle board one has a little more support to it. It has the one piece in the middle. Like Nathan mentioned it needs a little more in the front to keep it from racking.

+1I owned a small tropical fish shop with over a 100 tanks, I built many stands and even my own glass tanks.
I would not trust that structure with 80 gallons of water on top.
Have you considered centre sag? Many tanks on home made stand crack across the bottom because the base sags and the entire weight is on the four corners.

Unclear on this. You're referring to glass tanks? Glass only require support along the edge of the aquarium. Acrylic requires support across the entire bottom? Do you have any thoughts on the way commercial stands are constructed? Here's an example:I owned a small tropical fish shop with over a 100 tanks, I built many stands and even my own glass tanks.

these words confuse you ? oh boy!!!!That particle board one has a little more support to it. It has the one piece in the middle. Like Nathan mentioned it needs a little more in the front to keep it from racking.
