Stick with chlorine for the pool, not bromine. As far as whether or not to use the chlorine feeder, that depends on a couple of your water chemistry readings. We recommend having the Taylor K-2006 kit which you can get through the Amazon link in my signature. If you can, order one of the kits and then post a current set of water testing results and let someone here advise you further.
By the way, welcome to the Pool Forum!
