If you are familiar with KZ Coral Snow, which is $40 for a small 250ml bottle, then you will LOVE this at a MUCH discounted price. Picture is my personal bottle, all bottles will be completely full. This is the same stuff but at a whooping 97% purity! Price is $5.00 for 16.9oz. Bigger discount for larger quantities.
Coral Snow liquid filter media as well as a secondary biological facilitator for elements and nutrition.
