Important Notice
• Always consult with your local pool professional when any significant changes occur with your pool or spa. Your linked dealer will be able to pull up your test history at his shop in order to help diagnose the problem(s) you may be having. This program is designed to improve basic maintenance but conditions such as cloudy water, colored water, corrosion or scale can occur if maintenance is ignored. So take a water sample to your dealer periodically to test other factors such as metals and other measurements better handled by a professional. WaterLink® dealers are well equipped to give you highly accurate, rapid analysis and treatments while you’re in the store.

Needs bug fix

If you follow directions, it works mostly. Does not work with indoor lighting.
Set up an account but every time I login I will get a blank screen with no recourse. Need to uninstall the app and reinstall to be able to use it again. This has been the case since I tried using this since last year, now on iOS 11.2.5

Very Good almost 5 stars salt level not reliable

This a very good application to check your SI ( saturation index ) or water balance ! Everything is okay at the exception of the salt level warning .

Salt Chlorinators have specific minimum limit per model or brands, there is no standard level and I have mentioned 3 examples
Emaux above 4,000 ppm.

Astral 4,000 to 6,000 ppm

Hayward 2,700 to 3,400 ppm.

Basically if you have an Emaux Salt Chlorinator the application will give a warning with salt level at 4.400 ppm that according to Emaux perfect !

Unfortunately if the end user reduce the salt amount it will damage the Chlorinator Cell and in some case the mother board of the Chlorinator

The application should take into consideration the Chlorinator Model with the limits mini / maxi.
The input can be made manually, the best will be to bring the Chlorinator Model and get the limits of set up automatically in the application.
