Collecting rainwater for re-use is a brilliant idea and, in some places, an essential. Most allotments either don’t have hosepipes or ban the use of hosepipes, making rainwater collection essential.

Find out all benefits of owning a water butt in our water butts guide. In order to collect water, a water butt is a must and in order to keep your water butt clean and healthy, a water butt treatment is also a must.

Clean and feed

Envii Water Butt Klear is a truly unique water butt treatment and the first of its kind on the market. Not only does it clean your water butt, but it also feeds your plants. Typically, water butt treatments use sanitisers or disinfectants to kill bacteria and clean water. This water is then used to water your plants, introducing harmful chemicals into your soil biology and making plants more susceptible to disease.

Envii Water Butt Klear uses an organic blend of beneficial bacteria (including bacteria from our flagship product Envii Pond Klear). This safe non-toxic treatment targets the organics in your water butt that cause green water, foul smells and algae.

Healthy water all year round

After clearing water in water butts, they will maintain clean and healthy water all year round. Included within this blend of bacteria are a strain that have been proven to improve both plant growth and crop yields whilst reducing the risk of disease and pathogens.
