Lightbulb Brick in a PT

I'm looking for an economical solution for the way I want my tank scaped. It's 4ft x 4ft x 2ft high. I want to create shelves that rise like steps from the front to the back and I was considering using bricks.

Is there any obvious reason a clay brick would be bad for a PT?

I've used red bricks in a few of my tanks to create shelves and walls. I also use them to attach very large rhizome plants and cover them with different types of moss. Bricks are easy to work with because of their uniform shape. Clay bricks should be fairly inert (much like terracotta). The only drawback I can think of would be the amount of water they can displace inside a tank.

Egg crate and PVC is an option depending on what you are trying to accomplish. Bricks add a lot of weight, but they will work. I've used concrete pavers before for similar uses. It might add to your TDS or hardness due to mineral leeching so you may want to keep an eye on that if you have shrimp or other mineral sensitive critters in the tank.

I can't think of what would cause problems, I believe they are just fired clay.

Just make sure you get the actual clay bricks, and not the concrete/cinder ones.

Also, a bag of lava rocks is pretty cheap, and won't weigh anywhere near as much for the same volume. Would be harder to do a stepped/terraced sorta design, though.

Thanks for the replies!
Weight isn't an issue as it used to have 180lbs of live rock, the brick should actually be lighter!

I'm told there are some nasty bricks out there made with chemical but these are supposed to be a straight up fired clay.

THanks Again!
