Caribsea Aragonite Sand helps to raise and maintain a proper pH for your African Cichlids without the need to add chemicals. Arag-Alive has live bacteria in it which will help in cycling your tank faster. You DO NOT want to rinse this sand before adding to your tank as that will kill the live bacteria in it

I use Fiji-Pink Caribsea Arag-Alive substrate in my African Cichlid tanks to raise and maintain a proper PH for them.
