## Questions & Answers

**Q: Did this make anybody else skimmer go crazy after putting in the tank? Im getting all kinds of micro bubbles from my pumps now too.**
A: Yes.  It's the initial bacteria die off that causes that.  You should rinse the rock thoroughly in RODI water before adding to your tank to avoid this.

**Q: Is there a wide variety of sizes and shapes among the rocks?**
A: Yes and you can always break bigger pieces

**Q: Is this rock or sand??? 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.
