DO: Know the size of your pool It's important to determine the size and gallon measurements of your pool when determining which type of chlorine generating system is best for your pool. Although there are several types and sizes of chlorine generators on the market, not all them work efficiently in all types of pools. Remember, one of the goals is to save you time and money. If you purchase a chlorine generator that is wrong for your pool, you accomplish neither. DO: Compare the costs of pool maintenance to the costs of chlorine generators Determine how much money you spend on pool maintenance each year, and compare that to the cost of the chlorine generator you are thinking of installing. Remember that for most types of systems there are also installation costs. Also, estimate the costs of running the generator. If the cost of purchasing, installing and running the chlorine generator is more than you're currently spending on maintenance, consider a different system. DON'T: Install a brine chlorine generator If possible, steer clear brine chlorine generators. Although these types of generators are initially appealing, they often cost more to maintain and require as much effort as regular pool maintenance in upkeep. DON'T: Purchase a chlorine generator that does not constantly circulate water in your pool Generators that circulate water constantly maintain the best chemical balances and are the least amount of work for you. While other models that turn on and off with the pool pump are probably efficient, you still must maintain them, turn the pump on and off and monitor them. Purchasing a swimming pool chlorine dioxide generator is great economical move that also decreases maintenance as long as you know the right type of generator to buy and purchase one that is the size for your pool. Once you convert your pool to a saltwater pool, maintaining your pool is much less of a hassle.
