1 reading well out of range and 1 drifting. Follow the plan below to bring it back.

4 in range 1 drifting 1 out of range
Milky haze — pH is high — calcium falls out of solution and clouds the water Green bloom — sanitiser is low — this is what algae getting a foothold looks like

What to do now

In order — pH first, because it changes how everything else behaves.

1 Bring pH down from 7.69 to 7.50

Muriatic acid (31.45% / 20° Baumé) 3.1 cups (25 fl oz)
  1. Run the pump so the water is circulating before you add anything.
  2. Pre-dilute the acid in a bucket of water, then pour it slowly around the deep end with the pump running.
  3. Brush the area to disperse it and let the pump run for at least 4 hours.
  4. Retest before adding any more — this dose is deliberately about two thirds of the full correction.

Always add acid to water, never water to acid.

Never mix acid with chlorine, even in an empty bucket.

This assumes a total alkalinity near 100 ppm. If your TA is well off that, the acid demand changes — test it before dosing.

Dry acid (sodium bisulfate): about 1.9 lb (31 oz) instead.

Retest after about 6 hours of circulation before adding anything else.

2 Sanitiser level is low — the water isn't keeping up

Salt cell output Raise output by 30 percentage points
  1. Turn the chlorinator output up by about 30 points and extend the pump run time by 2 hours a day.
  2. Confirm the salt level is in range — a cell starved of salt quietly stops producing.
  3. Inspect the cell for white scale. Scaled plates cut output badly; clean with a 4:1 water-to-acid soak if you see buildup.
  4. Check pH first. High pH depresses ORP even when chlorine is fine.
  5. For an immediate catch-up you can add about 3.6 qt (116 fl oz) of liquid chlorine while the cell rebuilds.

Over the last 47 hours ORP has been turning back the other way, currently about 366 mV a day. Left alone that puts it near 333 mV in 8 hours further off target, so this amount is sized against that rather than today's 363 mV.

Don't swim until sanitiser is back in range.

Cyanuric acid above roughly 80 ppm suppresses ORP no matter how much chlorine is present — if ORP stays stubbornly low, test CYA.

Retest after about 8 hours of circulation before adding anything else.

Ensure that the filtration time is at least 16 h/day

Your water temperature is above 28°C (82°F) which will increase the likelihood of bacteria development. I suggest adjusting your pump run time to ensure proper circulation of chemicals. If you have a 24 hour variable speed pump, disregard this recommendation.

Add 6.3 lb of pH Minus - Gradual correction

Another recommendation may arrive in 6h if needed. Learn why... To protect your Total Alkalinity (TAC), each pH dosing recommendation is calculated to adjust your pH by up to approximately 0.3 points at a time. A larger correction at once could destabilize your water balance and require more chemicals overall. If further correction is needed, a new recommendation will arrive in about 6 hours. Why should you adjust the pH : Balanced pH ensures effective disinfection, comfortable bathing, and longer-lasting equipment. Important: If your readings seem inconsistent, run a calibration to verify their accuracy before dosing. Tip: You can adjust your pH thresholds anytime in your pool/spa settings. Always follow the manufacturer's instructions on the product label.

Increase the filtration time or power of your electrolyser

I suggest increasing your pump run time to optimize the efficiency of your salt generator and enhance disinfection.

The sensors may not be in contact with water.

Ensure the sensors are in contact with water and neither air nor debris obstruct them in order to continue receiving data and recommendations. If you removed the sensors from water for winterizing: - Activate the "Winterizing" mode in the application to suspend notifications. - Keep the sensors moist: fill the pH and ORP sensors end covers with KCl-storage solution and place these back on the sensor tips for re-use. - Store in a cool, dry place. If you receive this notification when your device is actually in the water, it may be because the device is not equipped with a conductivity sensor (v2 devices for chlorine or bromine disinfection). In this case, contact our support service via the app's help page.

Add 107.3 kg of salt

The level of salt is low. I suggest adding salt to ensure proper disinfection. This will increase the salt generator efficiency and protect its production cell. Caution: If the measured values seem inconsistent, check the accuracy of the measurements by performing an ORP calibration.
