## Description

All Aqua Natural gravel or substrates are 100% natural, sustainably sourced, triple washed and kiln dried. Our meticulously graded gravels and sands are the perfect natural substrates for any aquarium including planted tanks. Our high quality products create natural beauty combined with large surface areas for beneficial bacteria colonies and easy cleaning. Contains bio activated live nitrifying bacteria to either use as a primary substrate or mix with substrate for a healthy aquarium. Contains a patented blend of live nitrosomas and nitrobacter bacteria which break down and convert harmful ammonia, into nitrates.

Review: Great substrate! - 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.
Review: Loveee! - 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

### ⭐⭐⭐⭐⭐ Superior product - CLEARED my aquarium water within days
*by J***S on October 4, 2025*

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.
