Im getting all kinds of micro bubbles from my pumps now too.** A: Yes. It's the initial bacteria die off that causes that.

Description and title are conflicting** A: Supposed to be the rock. I had ordered it and ended up with 40 lbs of sand, told Amazon about it and they fixes the issue and sent me the rock **Q: Since this is not natural live rock how is it cultured to get the coraline algae?** A: Real aragonitic base rock with live spored bacteria, shipped dry. At an unprecedented 50% void space (macro and micro), you will be hard pressed to find a durable natural rock that has this magnitude of porosity. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***L on 21 August 2024* This product delivers just as you should expect!
