Worked Great
This gravel worked great I put some of this in my canister filter and it kept the PH right where I wanted it to be.

Great for sump
Great product if you want a sand that won’t blow around…the large grains stay put and not in your pump.Does need to be rinsed throughly but that not a negative.

What I needed for tank
Itâs a lot better than using sand
Mike Fina –
Coral chips for your aquarium or fish tank
Rather than using gravel, you can use coral chips for your aquarium or fish tank to keep the pH a little bit higher. The only negative is before you put this in your tank. You should rinse very well. Otherwise you will end up with some cloudiness in your water and that can take time to clear out..But once in the tank, it is a nice addition for the bottom, especially for African cichlids

Great saltwater or African cichlid substrate
Great substrate for keeping the ph level higher in your aquarium. Good choice for those who prefer a more gravel like substrate over sand. Crisp white color, and didnât take very long to rinse the full 40lbs I purchased.
