I posted this on RC but nobody has answered. Want to get started on this ASAP, so the quicker the help the better.

Thanks in advance guys?

Metric makes this alot easier, so first lets convert..

24 in = 61 cm
24 in = 61 cm
18 in = 46 cm

61 x 61 x 46 = 171166 cm*3 (centimeter cubed)

171166 cm*3 = 171166 ml

171166 ml = 171 litres
171 litres of pure water = 171 kg
171 litres of water (salinity 1.024) = 175 kg

So each tank weighs 175 kg or 385 lbs when full, acrylic is neglible.

I would say no, 1 x 2 wood is not able to support this weight, go 2 x 4.

My brain just exploded. But I will go with 2x4's. Thanks

What I was getting at is instead of using 1x2 lumber (or 2x4) cut strips of 1" ply 3" wide, build a frame the dimensions of the shelf you need, then add a couple cross pieces, screw and glue everything together and then put a 1" ply top on the frame, I will go take some pics of mine, hopefully make it easier to understand.

Something like this

If you cut the parts on a tablesaw everything will be straight and square (unlike buying a 2x4 at the lumberyard) screw and glue everything together and it will be more than strong enough. I build all my stands this way and have never had an issue.

I get it! But isn't that frame still built out of 2x4? Not trying to be rude...just don't want this thing to come crashing down in the middle of the night

The support underneath is basically a 2x4 pony wall that the platform sits on, if you are putting your shelves into a closet all you would have to do is screw thru the sides of the shelf into the wall studs. You have a pic of where this installation is going?

Wow MrFish that's a great idea. Glue + pocketscrews with that design and you have a very solid true surface! I'd swear some 2x4s are so bad you could play hockey with them!

Thanks, the platform in that pic is 72x36" checked it with a laser level and it is dead flat and level, even after filling the tank (3000lbs) there is no deflection. I have seen some commercial built stands that don't look capable of holding a flower pot nevermind a large fish tank, seriously who in there right mind would use particle board around water, that stuff gets wet and litterally crumbles to bits.
