i just set up this tank again after my first fish passed away. worried that this sand would cloud and murk up the water but PLEASED it did not at all. i would recommend pouring water in on a paper plate to avoid disturbing the sand. it’s beautiful !!

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.

It's sand so not much I can say about that really. Except that it's BLACK! I suppose I should have thought about that???? as it says 'galaxy'. But it also says 'Natural' so I assumed it would be a regular sand colour. I know it shows a little black on the bag, but again I didn't notice. I guess it's my fault, but it's really not clear

Es un muy buen producto para un ciclado perfecto, y mantener parámetros adecuados. No es sustrato para plantas, no es para filtraciones. Es bacteria en modo sustrato
