125g Cinderblock Stand

[BlueJacks]

Looking for advice I have the standard cinderblocks laid with a 6ft apart.
Should I stack them with the open ends out?
Also I was going to do cinder block side by side on each end stacked 3 high.
Also have 3 4x4s for under the tank.

noticed On one end of the blocks it’s Off level a bit.

will be buying plywood for on top of 4x4s would 2x4s be good enough?

Cinder blocks are strongest when the holes point up and down

2x4's will have too much deflection/bend over a 6ft span unless you double them up on each side. Three 4x4's should be ok, just make sure they're good quality, dry, and straight. Personally, I would use 2x6 and build a 72"X18" frame to put on top of the cinder blocks.

Someone on here misread my original post. I used 2 4x4 posts and build a frame around them and capped it with plywood. Tanks filled up running now isssues for a week now. Tank is still on level width wise and and length wise. So far so good, 2x6s I used for my 40gal breeder rack
