Answer:

Pool chlorine generators can be very effective. They continuously produce chlorine which can lower the cost and maintainence of adding chlorine regularly. However, there is different maintenance required with these systems. Find out how long the "cell" will last and the cost of replacement. This may offset any cost savings from lowering your chlorine usage. Also, test and balance your other parameters regularly - pH total alkalinity and cyanuric acid (stabilizer). The chlorine generator does not prevent the need to keep these other parameters balanced for water clarity and equipment protection.
