SpaBoss pH Minus
SpaBoss pH Minus can be added by the capful to lower pH and alkalinity levels that are too high. Testing your hot tub water regularly, as often as once a day, will help you keep the levels in the safest range: pH level of 7.2 – 7.8 for most hot tub systems, and alkalinity between 80-120. Use your test strips according to the directions to keep a close eye on these levels.
Cloudy water and scaling can happen if your hot tub water has pH and alkalinity levels that are too high. Keeping these levels in the recommended range allows your other chemicals to work effectively and maintains clear and healthy water. One cap holds 1 oz of SpaBoss pH Minus.
- Add pH Minus 1 oz at a time for every 250 gallons if the pH level is between 7.8-8.0. If the level is higher than that at 2.0 per 250 gallons.
- Test after 1 hour and add more pH Minus as needed.
- Test the hot tub water regularly to keep levels in a healthy range.
