I'll update once I do something with it. Got two flat band saw or something pieces (base pieces, 40lbs kit), the rest seem like they can become something awesome after breaking apart and regluing. So far very happy with it.

I ordered this 40lb package of reef rocks. It came with 6 large rocks, a medium one that Im using as an island and various smaller ones as well which made nice additions for the overall aesthetic of my tank. I had 2 live rocks and a arch rock (purple) prior to getting these. I would definitely recommend this if you want to get a good bundle for a great price!

This was the perfect amount of rock for my 75 gallon tank. Also, as I rinsed off the rock before putting it into my tank, I was surprised how little dust/crud came off. Probably one of the best value purchases so far in setting up my tank.

It's not lightweight if you have lifting limits. It's 40 pounds, lol. It's amazing! It's perfect. My advise... Buy it!

The quality of the rock is very good. I was hoping for one or two larger pieces but I received what I would consider medium and small pieces. This would be an excellent purchase for a small to mid-size tank.
