FROG Target Total Alkalinity Increaser for Hot Tubs & Swim Spas – 2 lb Bottle with TruDose Cap

Keep your hot tub or swim spa water balanced with the FROG Target Total Alkalinity Increaser. This fast-dissolving formula is designed to raise total alkalinity to help stabilize pH, which can reduce swings, protect surfaces from corrosion and scaling, and support your sanitizer effectiveness. The result may be a more comfortable soak and clearer water over time.

Two standout features include the FROG TruDose Cap, which securely seals the bottle to prevent spills and provides standard cup and tablespoon indicators. The translucent measuring cap enables quick, accurate dosing, so you can move through maintenance without complicated calculations. Clear usage instructions pair with a simple test strip to help you read results without guesswork.
