Top quality product

I needed to change the substrate in my small marine aquarium. I talked with my local store where I purchase all of my supplies, and they recommended this. No waiting

I needed to change the substrate in my small marine aquarium. I talked with my local store where I purchase all of my supplies, and they recommended this. No waiting for the tank to cycle and the cloudiness was gone in a few hours. My water tested good the first day, and has been perfect since.

Solid product

So pretty for the bottom of my aquarium I liked the idea of using this instead of just plain live sand

Very goood

The sand is a mixture of small shells and white sand. It looks very nice if thats what you’re looking for. The water does get cloudy after you first add the sand

The sand is a mixture of small shells and white sand. It looks very nice if thats what you’re looking for. The water does get cloudy after you first add the sand but this happens with pretty much any sand you get. It was well packaged with no leaks and came with a good amount of water in the bag for the bacteria.

Beautiful sand

This is gorgeous sand. I’m so happy with it. It has lots of shells and looks so pretty. I added it to a bare bottom QT tank and it went in super clean with no dust/clouding
