Call in the pros. Take a sample of your water in a new, quart-sized Zip-loc bag to your local pool supply store. They can test for many more variables than are available in a home test kit, and will recommend exactly which chemicals you need, and how to use them.
Alkalinity first! First check to see where the total alkalinity is in PPM, then determine how many PPM change is needed to reach your target reading. Caution, I alway aim for 10 to 20 PPM below my ideal reading, because when you begin to adjust the pH, the TA will rise.
Use a chemical called "sodium bicarbonate" or "alkalinity up" - the dosage is 1.5 lbs for every 10000 gallons and 10 ppm. (So, 1.5*(gallons / 10000)*(ppm increase / 10)=amount) Mix with water in a large bucket and pour it around your pool.
There are ppm's to chlorine, pH, alkalinity, water hardness, copper etc., etc, etc, etc. Rethink and ask in a different format.
The same as a non-salt system pool. Disregard answer above. The only reading that will remain constant, in the above situation, is the alkalinity =80 - 120 ppm; pH = 7.4 - 7.6 For a salt system pool your conditioner/stabilizer should be slightly higher than a namually fed pool. You should achieve readings of 75 - 85 ppm.

It could be, but sounds more like hi alkalinity. Check your TA ( total alkalinity ) It should be between 80-120 ppm. You can bring it down using muriatic acid if you need to.

1. M-Alkalinity (also known as Total Alkalinity) measures the amount of carbonate, bicarbonate and hydroxide present in terms of "ppm as calcium carbonate". ( M-Alkalinity measurement is based on a sulphuric acid titration using a Methyl orange indicator that goes from yellow at a pH of 4.5 to orange at pH of 4.4 at the endpoint.) 2. P-Alkalinity measures the amount of carbonate and hydroxyl alkalinity present in terms of "ppm as calcium carbonate". P-alkalinity is measured down to a pH of 8.3. The M-alkalinity is measured down to a pH of 4.3.
200 ppm is 0.02%
Total alkalinity is closely associated with pH but rather than a measure of hydrogen ion concentration it is a measure of the ability of a solution to neutralize hydrogen ions. Expressed in parts per million (ppm), total alkalinity is the result of alkaline materials including carbonates, bicarbonates and hydroxides - mostly bicarbonates. This acid neutralizing (buffering) capacity of water is desirable because it helps prevent wide variations in pH whenever small amounts of acid or alkali are added to the pool. Total alkalinity is a measure of water's resistance to change in pH.

The accepted range in the pool industry is 80-120 ppm. If using isocyanurate chlorines, 100-140 is more acceptable. The reason is that as cyanuric acid levels increase, the more it gives a false reading on most test kits for Total Alkalinity. Use a Taylor Test Kit and read the instructions, especially the last page where it explains the formula for getting a true TA reading.
