ROX 0.8 is extruded (little pipes) whereas this stuff is not according to Eli. Not sure performance-wise but I imagine 0.8 has fewer fines.

Extremely intriguing.
Will have to try some when I do run out.

I picked up some from Eli early this week, what I can tell you at this time is that it rinsed very clean, no residue, I put some in a mesh bag and run it passively, my water is crystal clear - had to go out of town and won't be back till Monday, but the 2 days I was home for was really impressed with the clarity of the water

I haven't used Rox from Brs so I can't compare, also, I used only a small amount since I was going to be away

That's all I have for now

That's good.
Every bit that we can observe and contribute helps, right??
Hopefully we can hear more from others who have used it to chime in.

I think the main difference is price. If I bought 15 lbs of BRS ROX for around $250 I'd pay about $16/lbs. Or "Granulated Activated Carbon 25lbs/$225 That is only $9/lb Free shipping CANADA WIDE" http://caco3reef.com/activated-carbon

It also has a larger surface area: 1225 m2/g for BRS ROX and 1670 mg2/g for his.

what size and shape would you describe it? BRS ROX is literally the size and shape of this "i" , but without the dot.

Thank you for the input.
There are few people already using the product and we should in the next week or so see some more input from some of us on canreef.

Eli, is the weight/volume the same with your carbon as it is with Rox 0.8? 15 Lbs of the 0.8 is 5 Gal, is your Rox 1.3 the same?

One more thing: you need to update your home page, the sale is shown as ending on May 4th.

hanks for heads up on the wrong date:biggrin: my bad.
Yes a 15lbs of Rox 1.3 will fill a 5 gallon pail.

I'm thinking it's time to place and order. It would be nice to hear a couple of members experiences. The last order of rock and chemicals went exceptionally well, I'm very happy with my purchase! Sounds like you're doing an awesome job in the customer service department, nice work Eli!
