This exact rock. Wysiwyg. I planned to seed this rock and used it. I loved the look. I made them using cement and crushed coral/aragonite about two years ago. The soaked for 2 months. This pic was taken durring a 2 week soak. They should be fully cured and ready to go. That should be plenty of rock for a 50-75g aquarium. It is very porous. Water will fall right through it in places.

Once again, this stuff has had plenty of time to soak. Just to make sure, I changed the water about every 3 days during the last 2 weeks. A few pieces were saved from my tank teardown.
