Chemical Compatibility
pHin chemicals are compatible with the Sutro monitor. They can be selected by scanning the bar code of the chemicals while setting up your chemical profile in the application. If for any reason the chemicals cannot be scanned in, the equivalent chemical from the default chemicals can be selected.
Both methods will give the same recommendations, however, the name of the chemical will be the one that was selected.
Recommendations
The recommendations for pHin chemicals are not fully converted due to pHin's pre-measured pod design. Full support for pre-measured chemicals may come at a later date if additional companies continue exploring this method of treating water.
In the near term, please use the following tables to convert from the Sutro recommendation to the number of pods required. If the number is not even, it is safer to round down to the nearest whole pod so as to not over treat. The Sutro monitor will test again within 8 hrs to make any corrections.
Spa Chemicals
pHin Spa Chemical | Recommendation |
Dark green striped pods | Partial compatibility: Set as secondary sanitizer, set primary sanitizer to brominating salts. Add 1 dark green striped pod when recommendation for brominating salts is present. |
Crystal Shock Oxidizer | Partial compatibility: Set as secondary sanitizer and set primary sanitizer to brominating salts if bromine. For bromine, add 3.5 tbsp when recommendation for brominating salts is present. Otherwise follow manufacturer instructions for chlorine spas. |
Red striped | Add tablet to dispenser when notified in the app. |
Orange striped pods | 1 pod = 2 tbsp pH up |
Yellow striped pods | 1 pod = 1.5 tbsp pH down |
Purple striped pods | No compatible chemical. Add 1 pod at startup to build a bromine reserve. |
Pool Chemicals
pHin Pool Chemical | Recommendation |
Light green (chlorine tablets) |
Add tablet to dispenser when notified in the app unless already present. |
Light blue (chlorinating sticks) |
Add stick to skimmer when notified in the app unless already present. |
Dark blue pods |
1 pd = 1 cup dichlor |
Dark green pods | Partial compatibility: Set as secondary sanitizer and use as manufacturer directed. |
Orange pods | 1 pod = 1 cup pH up |
Yellow pods | 1 pod = 3/4 cup pH down |
