Autoclaved aerated concrete as a live rock

Hello everyone,

I am new on this forum and I just wanted to share with you an experiment that I started few weeks ago. The idea is to take regular AAC ( for building), cure and shape it, and put it in the reef tank. As it would be too much risk to put a building material in the already formed aquarium, I decided to start a new one, and measure its progress. I searched everywhere and I just couldnt find that someone had been tried it, but because of its characeristic it seems as a perfect DIY live rock. Its porous surface would provide enough space for benefitial bacteria to grow, its lightweight, etc. The problem is chemistry, and question is will it, once soaked in water, leach something in it. The experiment is supported by the leading serbian reef aquarist ( and his company ReefrooM), and many people is following the progress every day. I am not going to write too many details now, but if you are interested in this project I will be glad to share more details, photos, test results and overall progress of the tank.

Cheers!
