About this item
- PRECISE pH CONTROL FOR POOL AND HOT TUB: BAYROL pH-Minus granules reduce and stabilise pH levels quickly and accurately. When pH rises above 7.4, chlorine becomes several times less effective, limescale builds up on surfaces and equipment, and water turns cloudy. Keeping pH between 7.0 and 7.4 is the foundation of clean, clear and well-maintained pool water.
- HIGH PURITY FORMULA FOR RELIABLE RESULTS: Made from high purity sodium hydrogen sulphate, BAYROL pH-Minus dissolves fast and completely with no residue. A precise, high quality formula that acts quickly and delivers consistent, measurable results every time - no guesswork, no waste.
- SIMPLE AND PRECISE DOSING - DOSING CUP INCLUDED: Add 100g per 10m³ to lower pH by 0.1 in swimming pools, or 10g per 1,000L for hot tubs. Add the granules directly to the pool or hot tub with filtration running, or dissolve in a bucket of water first then distribute evenly. A dosing cup is included for accurate, hassle-free measurement every time.
- COMPATIBLE WITH ALL POOLS AND HOT TUBS: Suitable for all pool sizes, all filter types and all disinfection methods - whether chlorine, bromine, active oxygen or salt electrolysis. Works with all pool surfaces and liner types.
- THE PREMIUM CHOICE FOR YOUR SWIMMING POOL: Developed in our own laboratory in Munich and manufactured in Europe, BAYROL is a recognised expert in swimming pool water treatment - trusted by pool professionals, pool builders and pool owners across Europe who want the best results for their pool, season after season.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
