Continue to Canada siteUpgrade your aquarium swagger with the Nature's Ocean Natural Coral Aquarium Base Rock. This natural, porous aragonite rock is filled with naturally-formed holes that not only look great in your set-up, but help maintain aquarium health by acting as a biological filter. Plus, the porous surface is the perfect environment for denitrifying marine bacteria to grow, which work to decrease your tank’s nitrate levels over time. The unique shape means every rock is one-of-a-kind, and also makes it easy to stack when growing live corals or adding to coral-based environments. Plus, the rock has been soaked in a deep water well to prevent leaching in your aquarium.

I was looking rock to aquascape with and this is the best deal I could find. Yes the order does come with 2-3 rather large pieces and 1-2 smaller size pieces to fill the 40lb mark. Picked up a $5 chisel and $20 of glue/activator and got to work. If you don’t want to put in the effort to build your own aquascape all you need is a $5 chisel and a household hammer. The rocks have natural openings/weak spots and it’s easy to break them into reasonable size pieces with a little effort. The smaller bits are perfect for the refugium. Note in the picture I did have one base piece to start but I also had a leftover 1-2lb rock and multiple fragments for future projects.
The reviews and pictures show a group of smaller-medium sized rocks adding up to 40lbs. I recieved my order today its 3 massive ugly rocks. Don't waste your money or time buying this product.
This rock was a really good value. I wanted to create my own aquascape and needed rock I could break into unique shapes. Customers should understand that this comes in 2-3 huge chunks of rock. You will need to break this rock up some if you don't want huge boulders in your tank. However, this rock was REALLY hard to break. I was able to use a hammer and chisel to get some chunks off but understand, it takes alot of work. Overall, great value for the money.
I sent one rock and it weighed 4.5 lbs. The picture showed multiple rocks and said forty pounds. I got one rock! The rock is really nice, wish there were 40lbs.
Arrived as described. 2 large rocks. Perfect for large tank.
For a 40lb box, we expected several rocks, however, there were only 3 massive rocks that do not fit our tank.
