Bigger tank rack plan any experience?

[mountaintoppufferkeeper]

The general idea is this sketch. The difference is the rack will be 3 blocks long then one sideways 

Using these 16x8x8 blocks

And 3/4" maple plywood in 2'x4' sections like the drawing. For this 270 gallon

Anyone done this kind of stand ? How far much of an overlap of plywood to block would you do? I am considering doing a cap stone for more surface area and resting the plywood on that vs the open block. 

Any guidance on this one much appreciated.

I’ve never done anything that large. I’m estimating that in at well over over a ton, right? I like thick plywood between the tank and block. I’d just make sure it goes on concrete floor.

Yeah I figure ill run it with about 250 gallons of water and 150lbs of pool filter sand. That plus the tank itself and the stand is basically the weight of parking a car down there.  The fishroom.is in the walkout basement

I'm not much help with the stands themselves as I just buy them as I need them but if you need any help with plumbing I can definitely help you there!
