So I'm setting up the 135g. I used the cement block in the past horizontally. Problem is I need to use the block vertically for height. Will this work? Which angle or placement should I use for best strength? I'm using 2x8 wood beams on top of block, under tank, with styrofoam under glass. Fast responses wanted. It's snowing, my house is torn apart, and my fish in tubs. Can't run out for more blocks. Thanks!
