What size tank are you making a stand for? If its not bigger than 300 gallons i wouldn't use cinder blocks. 2x4's and 4x4's would do just fine holding up 300 gallon tanks if built correctly. Here are some pics of the stands I built for a 75 gallon and 450 gallon.

Here is the basic design I used for both stands just used different materials.

Showing the added plywood top, I also put a piece of plywood on the bottom so the filter and supplies would have a place to sit.

The two frames for the 450. The brown wood are 2x4s and the green are 4x4s. the 4x4s are on the top.

The top with all the brackets before the plywood.

The cinder blocks getting put together before i filled them with concrete (each stack weights over 200 pounts)

The top, bottom and cinder block stacks put together and sprayed with a primer/sealer

The wood frame is also a lot easier to put a wood shroud on as well.

Back in the day, when I got my first BIG tank, a 135g, I did not use wood for support. Instead I use 2 1/2x2 1/2" angle iron. Less deflection. The 135g was only a 5' long tank. Three rows of concrete block 4-high. Fit right in with the rest of my decor, too. Including the peach crate end tables, papasan chairs, beanbags, TV trays, and concrete block stereo stand.

Leveling a tank that size is very important. Please bear that in mind when you set it up.
