splasher84,

I will do my best to help with my extremely limited experience with bromine. I don't think there is a "shock" per say but you can increase the amount of bromine that is made in the water using a granular product. There are also liquids but the general census is the granular is best. A quick search confirmed this and you want a product containing the oxidizing agent potassium peroxymonosulfate (aka potassium monopersulfate or monopersulfate compound). The liquid product is usually added monthly and adding more does not produce more bromine. The granular product is usually added on a daily basis or, as needed, and it is this product that results in bromine being produced. The potassium peroxymonosulfate reacts with the sodium bromide, already in the water, and forms bromine. Add more potassium peroxymonosulfate and more bromine is produced. After, the bromine has been consumed in the sanitizing process, it reverts back to sodium bromide, allowing for the cycle to be repeated. The sodium bromide product is added monthly to assure that there is always an excess amount of bromide, available to be converted into bromine. Now let me caution you that I obtained this info from old manufacturers sites. I helped a friend with a Bromine/Ozone generator spa for a while until I convinced him to turn off the "ozonator" and switch to chlorine. I must tell you he is much happier due not only to the money he has saved but also the results. He spends much less time dealing with cloudy/bubbly water now. I'm sure any pool store can fill you in and sell you all the products you can afford. Bromine will breakdown chlorine so to speak. As far as a link to a web site, I can't recomend any of them as they all are trashing chlorine for reasons that I know are bogus. I can however recomend yo go to the link below. It is the sister site to this forum and has nothing but the facts.....
