I’ve really enjoyed this substrate. I mixed it with my old substrate (which was a mix of sand + small gravel substance) when I upgraded tanks and I like the look of this one a lot. It’s more of a fine sand texture and a really beautiful sparkly black. My plants and ADFs seem to love it. It’s already a bit wet in the bag (they recommend not rinsing it) so it was easy to place into my tank that already had water in it. I love that it has beneficial bacteria to help the tank cycle too. It did make my water a bit cloudy for about ~2 days but this cleared up on its own with time. Read more

My aquarium has 12 goldfish ( fancy ) and a few pleco's. I have a very nice filter, but I could not get the water to clear up. Read about this product and within a few days, this substrate made a massive change - clearing up the cloudy-ness and now it is crystal clear. Buying a second because I LOVE the look of solid black substrate. Read more

I have used this in every single tank I own, betta, corydora, pleco, shrimp and loaches. They all love it! It helps the cycle process and helps keep plants nice and healthy. Kudos for the glittery specks that look beautiful under the lights Read more

Absolutely beautiful and works great. I mixed mine with some gravel I had. My water was very cloudy at first but cleared up in several hours. Read more

Beautiful sand the black is so sparkly. I love it, but it came with a surprise. A few snails were in the bag. Don’t love that. Read more

Love the color! It looks great! It is also a great consistency and made my plants stay in place, unlike the gravel on its own. Hoping this will help my plants come back to life. It was a bit murky right after adding water, but it was back to normal within a couple of hours. I used it in my 10 gallon tank, it covered the whole bottom and then I layered my gravel on top Read more
