Hi. Dichlor and Trichlor have very similar chemical structures and are therefore both used in disinfection of water, whether that be pools, drinking water etc. The by-products formed by both will be the same as it's not the source of the chlorine that are the problem with DBP, but what the chlorine reacts with once it's dissolved in the water. Both dichlor and trichlor dissociate quickly in water (to form hypochlorous acid/hypochlorite and cyanuric acid). If you want a slower release chlorine tablet, a tablet based on calcium hypochlorite is a better option.
