This powerful and effective sanitizer kills algae and bacteria. This alternative to chlorine is great for use in swimming pools, spas, and hot tubs. Our bromine is pH balanced so it is less harsh on skin, eyes, hair, and swim wear. Plus, bromine produces no chlorine odor, making it ideal for indoor pools. Since bromine dissolves at a must slower rate than chlorine, it must be dispensed by an automatic feeder. 100 lb. size is shipped in two 50 lb. buckets.
