the importance of water testing

Because it's such a small body of water, your spa requires consistent, frequent water testing and maintenance to keep it clear and comfortable. A simple rule of thumb: the more use it gets, the more it should be checked. Start by testing your water for present levels (always do this before adding any products). Here's what to look for & its target range:

Test Frequency Ideal Range
pH Twice weekly 7.2 - 7.6
Total Alkalinity Monthly 125 - 150 ppm
Total (Calcium) Hardness Annually or when fresh water is added

200 - 275 ppm (plaster spas)

175 - 225 ppm (all other surfaces)

Free Available Chlorine Several times weekly 3.0 - 5.0 ppm
Brominating Tablets Several times weekly 2.0 - 4.0 ppm
Brominating Granules Several times weekly 3.0 - 4.0 ppm

Spa Time 5-Way Test Strips are a simple, easy way to test your spa's water balance.  Spa Time 5-Way Test Strips test for total (calcium) hardness, chlorine/bromine, pH and alkalinity.  Read and follow instructions to the letter for best result and keep a log of all results and product applications for problem solving and predicting future maintenance needs.

Sunlight and environmental conditions can affect surface water samples and those taken close to the returns, that's why you should always obtain a water sample from "elbow" depth in the spa for accurate testing results. Always use fresh testing product at the beginning of each spa season as age, heat, high humidity and other factors can affect older reagents and strips.
