Using test strips to your hot tub is the best way to understand and examine the chemistry of your water which could easily go underdose or overdose and is crucial to be correctly balanced.
Maintaining water chemistry no longer only guarantees maximum enjoyment and chemical effectiveness but additionally allows minimizing undesirable impacts of chemicals. Testing hot tub water on a regular basis is important to keep away from peaks and valleys of sanitation and water stability which could cause problems for the hot tub or your body and is a key to good health.
Testing on a regular basis is not needed until your spa is used on day by day basis. Check your water 2-3 times in a week or greater if the spa is frequently used.
