If you have someone who is going to add bleach for you throughout the week, you don't really need to add the quart of Polyquat, although it won't hurt if you do. If you do decide to add it, just be aware that it will drop your cl level and then you'll have to bring it back up. If it were my pool and I had someone who would come by every other day or so to add bleach, I probably wouldn't add the Polyquat. In fact, I never use it except in the fall before I close my pool. Some people routinely add a little bit, but I never have and have never had any problems with my pool.
