I want to raise the whole unit not just the bottom shelf. Would cinder blocks be strong enough to hold 73 gallons?

I would like to raise my 48 inch  metal stand so the lower shelf is higher off the ground. The stand holds 1 - 40 long and 1 - 33 long. How can I safely raise it? I am getting to old to sit on the floor to do maintenance.              Thank You…….. Lisa
