I don't think anyone has addressed your basic problem. You need to know that all the saltwater system does is produce chlorine. You still have to monitor all the normal pool parameters including Chlorine levels. The only difference is instead of adding chlorine manually you ajust the Saltwater system to regulate you chlorine levels. All other pool parameters need to adjusted with the methods discussed here and at poolsolutions.com. Keep an extra vigilant eye on your PH level it will go up faster with the Saltwater system then with other chlorinating levels.

Also you will need to use bleach or some other chlorine source to get a high chlorine level in the pool to help kill the algae. Even in "boost" mode the Saltwater system won't produce more then 5-6PPM of chlorine. (at least mine won't)
