Balancing the Water
When initially filling or refilling your spa follow these
steps to achieve proper water balance.
Important! Always circulate the water for
at least 15 minutes after making any
chemical additions, before retesting water,
or adding any additional products.
1. Test the spa water using an AquaChek Test Strip
(see label for easy dip and read directions).
2. Determine the pH and alkalinity level of the water
using the color comparison chart on the bottle.
3. If changes need to be made to the pH and/or
alkalinity level to put them within the recom-
mended range, always balance the alkalinity
before balancing the pH.
The product(s) you should use to adjust pH and/or
alkalinity are Marquis pH & Alkalinity Increase or pH
& Alkalinity Decrease. Make any chemical addi-
tions per the directions on the bottle and then test
and repeat if necessary until all readings are in the
desired range.
4. After pH and alkalinity levels are in the recom-
mended range, you can establish a sanitizer
residual of 0.5 ppm. Add one-half ounce of
Marquis Chlorine per 500 gallons of water. Test
and repeat if necessary until there is a 0.5 ppm
residual of sanitizer in the water.
5. Upon initial start-up and every four months there-
after, insert a new Nature
2
cartridge into the
Marquis filter.
Water characteristics vary depending on the local
water supply. You may need to “fine tune” the spa
water due to these variances. Your dealer may
suggest the use of the following products when
filling the spa based on your water conditions:
Metal and Stain Control
If minerals such as calcium, iron, copper, or manganese
exist in your water supply, they can stain spa surfaces.
Marquis Spa Care Metal & Stain Control prevents spa
staining. Add per label directions for the gallons of your
spa each time you freshly fill the spa with water.
