Hi~
It's been a while since I've had any tanks and recently I've been wanting to set up a 20-long aquascaped tank. I'm planning to create plateau-esque shapes in the back corners by using rock rings to anchor substrate mounds in place. In order to save myself from buying a whole ton of rock substrate I was wondering if I could take a hammer to some old (but never used) terra cotta pots that I have lying around. My plan is to pound them into the smallest particles possible and use them as building blocks for said mounds with a sprinkling of gravel to cover. Is this koshir? I've read precautionary stuff about terra cotta raising pH, and I've also read that terra cotta leaches beneficial minerals (specifically iron) into the water that aid plant growth. Is any of this true? And will using terra cotta in a more processed form intensify these effects?

I think the biggest problem would be anaerobic bacteria pocketing where you can't gravel vacuum.

Terracotta pot sides can be used as bricks to support mounds but if you powder it it will clog.
Old terracotta is risky as plants are grown with pesticides and fertilisers and the pots are absorbent.
