The Easy-Life Filter Medium is a very powerful product for improving aquarium water. After the product is added, the water becomes cloudy, indicating that the product is working. The more pollutants there are in the water, the longer this cloudiness will last. The water cleaning time is a good indication of water quality. The cloudiness will disappear after a while and is naturally completely harmless.

• Normal cleaning time for aquariums: 4 - 16 hours
• For heavily polluted aquariums, the cleaning time may be extended up to 48-72 hours
