PRODUCT DESCRIPTION
Chemtex Pool Drop lowers swimming pool pH back into the 7.2-7.6 range. Above that, water feels sticky and drying, swimmers report itchy skin and dull hair, scale starts forming on tiles and the heater element, and - the reason it matters most - chlorine loses much of its killing power. A pool at pH 8.2 is doing a fraction of the disinfection it was dosed for.
Dose against the tested pH. Per 10,000 litres of water that is 80 ml at pH 7.6-7.8, 100 ml at pH 7.8-8.0 and 160 ml above pH 8.0; double those figures for a 20,000-litre pool. A 1-litre bottle therefore covers six to twelve full corrections of a 10,000-litre pool - a season or more of routine adjustment on a home pool, where pH usually needs nudging rather than rescuing.
The reason to buy a formulated reducer rather than muriatic acid from the hardware shop is what happens at the edges of a domestic pool. Neat acid splashes, fumes in a closed pump room, pits the ladder and the light housing, and cannot be dosed accurately by eye. Pool Drop is pre-diluted and non-corrosive, measured against a pH reading, and safe to keep in a garage with children in the house.
FEATURES & BENEFITS
- Holds pH at 7.2-7.6 — The band in which chlorine actually disinfects, scale does not form and the water stops stinging. Above it, your chlorine dose is largely wasted.
- Stops scale forming — High-pH water drops calcium onto tiles, grout, heater elements and the waterline. Correcting pH is cheaper than removing the scale afterwards.
- Non-corrosive — Will not pit ladders, handrails, light housings or filter internals, which is the standing risk with neat muriatic acid.
- No swimmer irritation — At dosing strength it causes no eye redness, skin irritation or allergy - the sticky, itchy feel of high-pH water goes away, nothing replaces it.
- Dose straight from the bottle — Liquid, pre-diluted and measured against a pH reading. No weighing, no dissolving, no acid handling drama.
HOW TO USE
- Test the water first — Use a pool test kit or strips before dosing. Dosing blind is how pools end up over-corrected, and a correction in the wrong direction costs a day of swimming.
- Work out your pool volume — Length (m) × width (m) × average depth (m) × 1,000 = volume in litres. A 10 m × 5 m pool averaging 1.4 m deep holds 70,000 litres. Every dose below is per litre of pool water, so this number is the only one you need.
- Read the dose off the pH — Per 50,000 litres: 400 ml at pH 7.6-7.8, 500 ml at pH 7.8-8.0, 800 ml above pH 8.0. Scale it to your own volume - a 10,000-litre pool needs a fifth of these.
- Dose along the periphery — Pour the measured quantity around the edge of the pool with the filtration running, so it mixes rather than sitting in one place.
- Wait an hour, then re-test — Keep swimmers out for at least an hour. Re-test and correct again if needed. Two small corrections are safer and more accurate than one large one.
