## Customer Reviews

### ⭐⭐⭐⭐⭐ Most Underrated Substrate for Reef
*by C***S on November 19, 2022*

Love this substrate. I actually like the grey color better than a true black. Under blue lights it still looks 'black' and provides excellent color contrast and pop to corals and fish, all while making the tank feel brighter versus a true black sand (I previously used black diamond blasting sand).One thing to note is that there is a broad range of particle sizes, all the way from fine dust to a few chunks up to ~8mm across. It does need to be rinsed thoroughly to remove the fines. The more you stir it and rinse it, the less particulates will remain in the tank. IMO it's worth it for this really unique substrate.I have a blue star leopard wrasse that is perfectly happy sleeping in this substrate. I also have a small Two Spot sand sifting goby that seems to be doing well. He likes to pick up and move around the larger pieces, then sift through the finer stuff underneath. There aren't any sharp edges on this substrate, it is very smooth.

### ⭐⭐⭐⭐⭐ Great stuff
*by S***R on July 14, 2017*

Im using it in my125 gal frontosa and kelberi peacock bass tank i like it so much i just paid 17 dol to get another bag with one day shipping fine enough sinking food doesn't get lost coarse enough not to blow aroundOk its not available for one day shipping and i wasnt charged shipping for it.i still have another bag coming and its worth the wait

### ⭐⭐⭐⭐⭐ Awesome!
*by C***O on August 28, 2019*

Came in the correct package and it looks incredible.The sand is gray and the best way to rinse is to use a fine mesh fish net and scoop 10oz at a time in and run water through it till it runs clear. Results are spectacular.
