Literally my first ever thread, so here goes.
On a reeftherapy podcast from reefbuilders some time back, the late Jake Adams mentioned something about aquascaping rocks being overpriced af, and that you can literally use cinder blocks instead. Is this a thing? I’m planning a 700gal and cement blocks (whole or sawed in half) would make a good base rock. I’ve seen it in a few reef tanks online but it’s not commonplace. I’m only taking it seriously because Jake Adams mentioned it. By cinder blocks I mean cement blocks, where I come from they’re made with local limestone and cement. That’s it.
Cons:
1. Concrete dust… they need to be pressure washed
2. Cement is basic… They need to soak in a bath of water until they stop messing with the pH
3. They ugly
Pros:
1. They’re strong, they’ll never break if you put heavy scaping rock on them
2. They’ll last forever
3. They have holes you can use as shelter if you have large tangs, angels etc
4. They’re cheap as chips
5. They’re very porous
6. You can easily cover them with live rock once the skeleton of the scape is done.
