This forum has opened my eyes to a number of procedures I currently have been using and need to change. I do currently work as a pool cleaner for a small family owned business and will be starting my own business this fall. I would like to maintain my pools as closely as possible to the methods described in this forum but realize that since i am at a pool usually once a week I will have to make adjustments. Out of lack of knowledge and improper training I currently add 2 to 3 pounds of granular di-chlor every week as a shock and after finding this forum realize i am spinning my wheels there. I also was taught to add tabs into skimmers and was wondering what the negative effects of this practice are? I look forward to dispelling myths and learning a correct and practical way of maintaining a pool.
