Calcium Hardness Increase
It is critical to have some calcium in your water,
however, the level of calcium should be between
200 – 400 ppm. High calcium levels can cause scale
buildup on spa surfaces and equipment. Your spa is
protected against high calcium by using Marquis
Metal & Stain Control when initially filling your spa.
Low calcium levels can cause spa water to become
highly corrosive and damaging to the spa equipment
and plumbing. To raise calcium levels, use Marquis
Spa Care Calcium Hardness Increase.
pH Lock
If your water supply requires constant adjustments to
keep your pH in balance, we suggest the use of
Marquis Spa Care pH Lock. pH Lock “locks-in” the
pH level when added to a freshly filled spa. pH Lock
maintains the ideal pH level for approximately three
to four months – until it is time to drain your spa.
Your Marquis dealer can provide all the necessities for approximately
four months of water care in one convenient package.
