Amerse pH Lock

pH Lock
A unique granular formation which adjusts and locks in the critical pH level of your Softub water. Improperly balanced pH levels in your Softub water can lead to stains, scale, equipment corrosion, & skin and eye irritation.

This product is intended for use in newly filled Softub Spas or other Spas, but can also be added to existing water. Under normal conditions no prior water adjustment is needed before using pH Lock.

NOTE: If local water conditions are extreme or Softub usage are very heavy, you must first use pH & Alkalinity Increse or pH & Alkalinity Decrease to bring the pH into general range of 7.0-8.0. pH Lock will then complete the adjustment and lock in the pH for 2-3 months so ongoing pH adjustments aren't necessary.


1. Add 16 oz. (half the jug) of pH Lock for up to 250 gallons of your Softub water or the entire 32 oz. for up to 500 gallons of your Softub water. Pour directly into the Softub.

2. Turn on the jets and allow the Softub water to circulate for 15 min. Temporary cloudiness in the Softub® may occur, but the water will clear once the product is fully dissolved.

3. Repeat the application each time you refill your Softub with fresh water.
