Using your skimmer net, remove as much large floating debris and “algae patties” from the pool as possible.
Protect metal fixtures
Use petroleum jelly to cover any metal fixtures (such as pool rails and pool light rims) in the pool. This will prevent them from becoming oxidized (discolored).
Add No Drān® Acid Wash
Add one (1) bottle of No Drān® Acid Wash per 5,000 gallons of pool water.
Drop Alkalinity to Zero
Add approximately 1 gallon of Muriatic Acid for every 1,600 gallons of pool water. It’s important that the Alkalinity reaches zero (0).
Brush the entire surface of the pool.
The next day, test your Total Alkalinity and add acid as necessary to keep the Total Alkalinity at zero (0). For every 10ppm of Total Alkalinity add 1 gallon of Muriatic Acid per 15,000 gallons of pool water.
Repeat Steps 5 & 6 Every Day
Repeat steps 5 and 6 for every day of treatment. Start the day by testing and adding necessary acid to the pool. Then brush the entire surface.
Once the stains are gone OR on the seventh (7th) day of treatment, begin to rebalance the pool slowly. Use a base demand test to estimate the amount of pH increaser you’ll need. Once the pH reaches 7.2 you may turn your pump system back on.
