How quickly will this product change my hot tub's total alkalinity?

FROG Target is designed to dissolve rapidly so you can see results within hours rather than days. After adding the calculated dose and circulating the water, test again to confirm the alkalinity level and repeat if needed.

• Fast-dissolving powder for quicker integration into water
• Use the TruDose cap to measure precise amounts
• Circulate the water for at least 15–30 minutes after dosing
• Retest with a reliable test strip or kit before making additional adjustments

Will this product work with my sanitizer system or salt setup?

Yes — FROG Target is compatible with all common hot tub and swim spa sanitizing chemistries, including chlorine, bromine, and salt systems. It focuses on raising total alkalinity and doesn’t interfere with the type of sanitizer you use when dosed per instructions.

How do I measure and add the right amount without guessing?

The included FROG TruDose measuring cap removes the need for improvised scoops and guesswork. The cap seals the bottle to prevent spills and features translucent cup and tablespoon markings so you can dose accurately every time.

• TruDose cap provides cup and tablespoon indicators for exact dosing
• Cap seals to prevent spills and keeps powder dry during storage
• Clear instructions and a dosage guide make repeat dosing simple
• Use a FROG or standard test strip to confirm target alkalinity

How often will I need to use an alkalinity increaser?

Frequency depends on bather load, water source, temperature, and how often you add fresh water. For routine maintenance, check total alkalinity weekly and adjust only when readings fall outside the recommended range.

• Weekly testing is recommended for consistent water balance
• Adjust after heavy use, water changes, or chemical shock treatments
• Proper alkalinity reduces the need for frequent pH corrections
• Keep a log of doses to track how much product your tub requires over time

Who is this for? FROG Target Total Alkalinity Increaser is ideal for hot tub and swim spa owners who want a reliable, fast-acting solution to raise alkalinity without complicated measuring. It suits homeowners using chlorine, bromine, or salt systems, plus anyone who prefers an easy, repeatable dosing method via the TruDose cap. If you test regularly and seek steadier pH control, this two-pack gives you spare bottles for seasonal maintenance and less frequent repurchasing. Always follow the product label and test after dosing to fine-tune water balance for your specific spa or tub setup.
