Water Purification Tablets FAQs

How many of these tablets will I need to treat a 1000 litre water tank?

For the treatment of water tanks, 10ppm available chlorine is normally recommended with a contact time of 10 minutes. These 9.7gm tablets have 3000ppm available chlorine when dissolved in 1 litre of water. Therefore you would need approx 3.3 Oasis 3000 9.7gm tablets to treat a 1000 litre water tank.

If you require a total tank disinfection rather than just a water treatment then a minimum 50ppm available chlorine is recommended with a contact time of 30 minutes, after which the tank will need flushing out before use. To fully disinfect your 1000 litre tank, you will need to use approx 16.5 - 17 Oasis 3000 9.7gm tablets.

Once I have used the Oasis 3000 tablets in the tank do I need to use the water quickly or will it be alright to stand for a period of time?

The water will be fine left for 3 days but this may need to be reduced if the tank is likely to get warm.

The manufacturers advise is that you leave 30 mins after purification before you use the water as drinking water.
