Waterline has the Swim Best Blackout Granular 90 50lbs available for purchase. Why buy this? For one reason, simply because of importance of sanitization 

Pools are vulnerable to algae growth as well as illness causing bacteria or other contaminants introduced into the water by swimmers. Chlorine based sanitizers are a strong, effective algaecide and disinfectant. They destroy the algae and contaminants to help keep the pool clean and clear. In addition, they leave a beneficial chlorine residual in the water that continually kills new algae and bacteria as it is introduced into the water. This protects swimmers from potentially harmful contamination and should be a critical part of any pool care program.
