Sutro is compatible with Frog @Ease SmartChlor!
Here's how to set it up
Update your pool profile
In the menu section, go to Pool & Spa and then click Sanitizer. Choose FROG System Bromine or FROG System Chlorine depending on what type you use. Also check Mineral.
Add Frog @Ease to your chemical profile
In the menu section, go to Chemicals and click Primary Sanitizer. Scan the barcode for your FROG product and save.
If your fCl is < 0.3ppm (or your bromine is < 0.675) then you will receive your FROG recommendation.
