About this item

  • RESTORE IDEAL SWIMMING CONDITIONS: Pool & Spa pH Increaser raises pH in pool water. Also known as sodium carbonate or soda ash, this product will raise pH levels under 7.2.
  • NON-CORROSIVE GRANULAR FORMULA: Use soda ash instead of using splashy chemicals to fix pool pH. Simply measure and pour into your pool for lightning-fast pH adjustment.
  • INCREASES CHLORINE EFFECTIVENESS. Sodium carbonate stabilizes chlorine and other pool chemicals, stopping skin and eye irritation for swimmers.
  • PROTECTS YOUR POOL EQUIPMENT AND LINING: Pool & Spa pH Increaser stops corrosion of equipment, etching of plaster, and pool discoloration from dissolved materials.
  • 30-DAY MONEY-BACK GUARANTEE: We value our customers, and we stand behind all of our products, 100% with no questions asked. If you are not pleased, call or email us with your order number and we will reimburse you in full.
