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

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.

Beautiful!! Healthy for my tank. *by on Reviewed in the United States 21 August 2024* This product delivers just as you should expect! I received many large pieces including arches, pass=thru holes and caves. Nothing was broken, just a couple chips.SO pleased !! I am setting up a 75 gallon tank and deciding to take the most organic approach possible without killing myself. So far real good!! I dropped it right in fresh out of the wrappers. No dust, no water fog and instant upgrade !! The look of this rock is stunning! It's instant reef !! Most importantly with no pest or algae infestation. Just INSTANT beauty and depth!! I understand there are many different saltwater paths I can take using this rock as the foundation. I plan on adding even more and introducing this to my 46 gallon Bowfront of 20 years. All the experts, pros and hobbyist were right.....this rock is a brilliant and safe addition to your marine aquarium for tank health and beauty. ### ⭐⭐⭐⭐⭐ Perfect! *by on Reviewed in Canada 9 April 2025* Delivered 41 pounds, great sizes and shapes with caves / donuts and more, package delivered with car well wrapped! ### ⭐⭐⭐⭐⭐ Great all the way around. *by on Reviewed in the United States 14 July 2025* Great rock for a great price.
