Water purification tablets FAQs

Hello, we are looking for a tablet to use to treat a 5000 litre tank with 1ppm. Can you help?

For a dilution of 1ppm for 5000 litres, you could use our Oasis 1000 tablets. You would need 5 Oasis 1000 tablets for 5000 litres.

Alternatively, you could use our Oasis 3000 tablets which require 1.6 tablets to treat your 5000 litre tank.

How long does one tablet last for in a household water tank?

This one is simple but there are variables involved. If the user has used the correct number of tablets to disinfect the water then the water will remain safe to drink. But if the user adds more water to the tank before the clean water has been consumed then the water will need to be disinfected again.

Also if the tank is kept in direct sunlight or in a warm area, this may affect the water compared to it being kept in a cool dark area.
