SPA CHEMICALS GLOSSARY
1 - Alkalinity Up: The total alkalinity of your spa water should be be-
tween 80-140 PPM. A proper alkalinity will help buffer your spa water
against sudden changes in pH. Every 2.5 tablespoons of Alkalinity Up
will raise your alkalinity by 10 PPM in a spa holding 500 gallons of wa-
ter.
2 - Bromine Tablets: These slow-dissolving tablets work especially well
in the hot water of your spa. Keep a base of tablets inside of an in-spa
oater/feeder in order to maintain between 2 and 5 PPM. Add 2 tablets
per 100 gallons of water and adjust the oater’s opening to regulate the
PPM level.
3 - Foam Gone: Foam in spas is typically caused by residue from soap,
shampoo, and cleansers. A small amount of Foam Gone will dissipate
the foam and will not affect the water balance. Most foam removers are
compatible with all sanitation programs.
4 - Liquid Filter Cleaner: Regular use of Filter Cleaner will greatly
increase the life and performance of your lters by cutting away grease,
body oils, scale, and lotions. Clean lters also contribute to better water
circulation and superior spa performance, because dirty lters can sub-
stantially impede water ow. Keeping your lters clean with lter cleaner
will also help keep your water ltered and clear. This is accomplished by
mixing one pint of lter cleaner with 2.5 gallons of water and submerging
the lters in the mixture for at least 12 hours.
5 - Dichlor Grandular: This concentrated, stabilized, and quick dis-
solving chlorine granular is simple to use in your spa as a sanitizing-
shock treatment. The downside to Dichlor is that it will not sustain a
PPM base for long in hot water. However, as a rule of thumb, if you treat your
water after bathing with half a capful of Dichlor, you will maintain clear and
comfortable water, providing your pH is controlled and your lters cleaned.
Dichlor dissolves quickly and leaves no residue.
6 - pH Down: If your pH level remains high, you can struggle with scaling,
cloudy water, rapid sanitizer loss, and possible skin and eye irritation. pH
Down can be purchased from your dealer in either liquid or solid granular
form. Please see your dealer for recommended dosage.
