DIY Stand - Cinder Block, hole side out/ wrong way

[PhilMStudy]

Does anyone know what the load capacity is for cinder block stacked the “wrong way”?

I am setting up a 15g QT/Planted marine tank and wanted to use existing cinder block facing the wrong way…

can it support that weight?

I would imagine no matter what way you put a cinder block it will support a 15 gallon

A block stacked the wrong way will hold thousands of pounds. You are good to go.

Roughly 10 pounds a gallon with rock and sand. Pretty sure no matter which way you put a cinder block it will hold 150 pounds.
