Sodium Bicarbonate 50 lb Bag | Alkalinity Increaser for Pools

Pool-grade sodium bicarbonate for raising total alkalinity. Yes, it's basically baking soda — but pool-grade 50 lb bags are significantly cheaper per pound than grocery store brands. Total alkalinity is the foundation of your water chemistry. If it's too low (below 80 PPM), your pH will bounce all over the place. 50 lb bag of pool-grade sodium bicarbonate Raises total alkalinity without dramatically affecting pH Ideal range: 80–120 PPM Dosage: ~1.5 lbs per 10,000 gallons raises alkalinity ~10 PPM ⚡ Pro Tip from Our Techs: Broadcast sodium bicarb across the deep end with the pump running. It dissolves fast and won't cloud the water. If you need to raise both pH and alkalinity, do alkalinity first, then adjust pH separately. Getting the order right saves you from chasing numbers all day.
