Cinder blocks?

I decided I need to add some terracing to my 90g soon to be dutch aquascape and found some cinder blocks outside. My plan would be to burry the cinder blocks under the substrate to create raised parts without spending a million $ on aquarium rock and substrate.

I know many rocks can change pH but I was wondering what this forum would think of me berrying the cinder blocks, I'm sure it would still leach some but would it be tolerable for plants? Tank currently has no fish

At least I can grow Algae

To the extent that cured cement leeches anything, my long search online on this information for my own purposes never revealed anything. In fact many fish breeding facilities in the united states and abroad use raised cement ponds or tubs to rear fry.

Anyway while this would work fine, you would be better off going to the hardware store and buying some lava rock to do the same thing. If you want to create terraced levels that do not need to be burried in substrate then look into using eggcrate ziptied together for that purpose.

Appreciate the response 🙂

I had originally wanted to do lava rock and would if I had some lying around but for the amount I would use it isn't worth it to me. Can you give me an example of the eggcrates ziptied together? I can't picture that but may want to try that

baked clay bricks is also an option

as for the egg crate idea (basically just boxes or platforms made from eggcrate), you can use the oatey fusion pvc glue to bond em together if you dont want to use zip ties. https://www.homedepot.com/p/Oatey-10...6683,1013,6960

Example from my scape.
sidenote: The eggcrate at the bottom of the tank isn't mandatory, it was there just in case I would drop a rock or something lol

Tsing's got it right of course.

Incase you need more (and because I already found it before reading Tsing's post ;P ) here is an instructable where someone was building a platform:

First off I'm digging that hardscape. Second, I'm not sure I'm saying it right or you guys are understanding me, what i want to do is place the bricks at the back of the tank and cover them with substrate to create a lot of depth and because the tank is so tall also allow some plants to reach near the top.

I saw sings post first and read it and commented before seeing yours, yes this is what I'm talking about when I want terraces. I'm going to look some more into that and see what materials I have laying around. Is that foam stuff for sure not toxic, I'm very skeptical of anything that foams being in my tank

oh yeah you can do that easily with bricks, like this right?
