CaribSea Aragonite Aquarium Sand - 10 lbs - Natural Substrate for Marine & Reef Tanks, Supports pH Balance, Enhances Coral Growth & Water Clarity

I bought this to use in an opae ula (Hawaiian shrimp) tank. They're doing well with it. You should note that it will be helpful to rinse it multiple times, like ten or more, to reduce the amount of fine material that will take a couple of days to settle when disturbed. And you will never get it all rinsed out. I'm not reducing my rating, however, because I understand this is normal for aragonite.

This stuff looks great in my tank however you do need to do a lot of rinsing. As long as you rinse it really well it will only take a day to clear up and will make your tank look great.

Good gravel, but very very dusty. Needed many many rounds of rinsing.

I used this sand for a 8g rectangle aquarium mixed with a plant substrate for nutrients. I had to wash it out at least 10x, until the water was cloudy, but not milk colored. However, they have a lot of sand for a good price. The sand is a nice cream color, which looks good and makes the dark gray rocks stand out. The plants are doing well and the betta, Wonder, is also doing good. The first day it was cloudy, but it got better fast and by the third day, the water was crystal clear. I am happy with this sand, and would buy again if I need more for cheap. Thank you Petco!

Good for my bichir tank brings his color out

Crazy cloudy water like milk. Will waste more water cleaning it than it’s worth. Maybe I got the wrong stuff this isn’t like normal sand.

Very nice just what I needed

The media could not be loaded. I know there’s ONE STAR reviews saying it stays foggy for a long time and doesn’t clear up. My 55 gal tank is crystal clear with this sand in it you just have to wash it VERY thoroughly. I washed one bag at a time in a 5gal bucket for the best results. This sand looks amazing. The picture below literally doesn’t look like there’s water in there but it’s filled up.
