Having trouble keeping your pH down? Use pH & Alk Potion to lower pH and slowly bring down total alkalinity to 80-100, typically within 1-2 weeks by using 1 tsp per 100 gallons every 2-3 days. Check alkalinity every 3-4 days until reaching 80-100. Once these levels are reached, pH can be controlled with white vinegar.

DO NOT USE if alkalinity is below 80 ppm.

Use of Magic Potion, once alkalinity and pH at correct levels is will help stabilize alkalinity and pH.
