1. SWCG (salt water chlorine generation) system are just a METHOD of adding chlorine. And, that's all they do. All the rest of pool water management (pH, CYA, TA, CH) has to be done the same way, PLUS you have to track salt levels.

2. Use labeled filter sand.

3. Few SWCG's generate enough chlorine to handle problems, like algae or a big group of sweaty kids. If you depend on them for that, you tend to (a) not solve the problem and (b) shorten the units life . . . a LOT.
