Ef-Chlor 1.67gm Water Purification Tablets for Purify Overhead and Underground Tanks Water

Tank Water Treatment – A Healthy Tank Water Is Just Tablets Away

Regular water treatment is necessary to keep your water safe for consumption

Many water sources throughout the world remain contaminated and require some form of disinfection. Filtration cannot be trusted as it does not remove viruses. For over 100 years, chlorination of drinking water has been one of the single most effective means of improving public health in the developing world…

It is very important to purify the water you drink or use for household/commercial purposes because unwanted germs and bacteria may cause water-borne dreaded diseases.

    Just as described.

    I used it with my 1000 liter loft water tank. The tank was quite smelly. Two tablets removed the smells completely. No idea if the water was disinfected because I have no means to check that.

    Value for money.

    It works well. Simply drop one tablet for 500ltr tank. It disinfects water. Controls formation of fungus in water tank. Getting smell in water.

    Good chlorine tablets

    Tablets were exactly as described, and were added to my underground water tank. Hopefully the tablets have worked, as a little bit of chlorine smell is sensed in the water. Recommended.

    Work great

    Product is working great so far. And after mix this tablet in my overhead water tank the water is good for cleaning, drinking, bathing, washing clothes, etc but you can’t use it for plant or gardening cos after use that water plant don’t grow fast as they should. So that’s my advice don’t use tablet mix water for plant or garden.
