*by T***D on 25 December 2025*

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.
