What to do with bromine dust

Hi all, I’ve accumulated a lot of bromine dust in the bottom of tablet containers over the years and was wondering if I could add it to my chlorine pool this spring when opening to help maintain shock levels during SLAM. Is this crazy, dangerous, stupid...? Appreciate your thoughts. Stay safe!

It’s a very bad idea. If you put bromine in your chlorine pool it will effectively add bromine as part of your overall sanitizer concentration. Bromine can not be stabilized against UV photolysis like chlorine can and so it will constantly be reduced by UV then regenerated by the chlorine you add to your pool. It will look like you have a higher overall FC loss and it may affect your ability to pass the OCLT at the end of a SLAM. Keep the bromine out of your swimming pool.
