Review: Great product - Great assortment of rocks package arrived great and looks good in my aquarium.
Review: Awesome Life Rock! - I got several beautiful arches and one big cave. They were packed extremely well, but one arch was broken. However that's not the fault of the company, I saw my mail person slamming the box on the ground (it is heavy). I was able to glue it back together and my reef looks amazing!

### ⭐⭐⭐⭐⭐ Amazing product
*by C***O on November 20, 2024*

I am very happy with this product. The arches are nice provides a ton of coral, anemone, and fish spots. One small broken piece, I honestly kinda wish there were a few more broken pieces for the filtration! lol all in all money very well spent and if I set up another tank, 100% using caribsea again!
