Very nice rock

[RIPTANK]

Damn! Those are niiiiiiiiiiiiice rocks! Going to place an order now!

Thanks for the nice comments. Reefer Rock is not only a great rock for its bio-filtering capability but a very nice looking rock as you can see with the pictures in this thread and the ones on the website.

The rock is fairly consistent from piece to piece in its characteristics. You can't go wrong by using a natural calcium carbonate rock that was formed by an ancient coral reef (geologically young compared to some of the dry rock that have been sold in the hobby over the years).

Can you give us an idea of how dense it is?

I bought "reef rock" at a store. Even though it was 3.50/lb, the pieces were SOLID rock with nice holes. I think it was comparable to texas holey rock (for any african cichlid fans out there).

3.50 - A nice sized piece of rock was about 2.75lb
6.99 - A piece of fiji premium (approx same volume/size) would have been 2b lb
2.99 - Tuffa rock (similar size) would have been 1.5lb
3.99 - Petrified rock (for reference, i'm sure you've seen this stuff) would be like 5-6lb!

Reefer Rock is typically slightly more dense then typical Fiji Rock (some pieces more some pieces less) - Fiji is full of macro/micro pores while Reefer Rock is full of holes and crevices from 1mm to 1inch in size. I would say on average that a 3lb piece of Fiji would equate to a 3.5lb piece of equal sized Reefer Rock.

Just as a quick sample see the following.

thanks for the reference.

I'm keep eco reef rock in mind when I setup a tank for my brother.

Is this rock mined in Canada?

[EcoReefer]

No, it is mined from a quarry in the US (far south). There is natural calcium carbonate rock available in Canada but due to its geological age its way too dense to be used as a reef suitable rock. The Reefer Rock is from an ancient coral reef estimated to be around 100,000 years old. Just for reference whats in Canada is millions of years old and therefore more compressed, more dense.
