Super nice for hot tubs.
These granules are easy to measure and dissolve, and they reliably bring the pH back into the ideal 7.2–7.6 range after testing the water. The instructions are straightforward to follow and results show within a few hours, making routine water balancing simple even for beginners. For the 1 kg size the tub lasts a long time, so it offers good value while keeping hot tub and pool water clear and pleasant to use. Overall, it does exactly what is needed with no fuss, so it fully deserves a 5‑star rating
