Get clearer, cleaner water for less by opting for Swell's Control Green Water solution, designed to quickly rid your pond of the causes of green water. Comparable with major branded products, this version is sold cheaper because it's our own - passing savings on to you.
Swell Control Green Water contains a mixture of friendly bacteria that can help reduce the levels of nutrients which encourage algae to grow. In addition to being easy to dose and use, it is also completely chemical free and can treat a 1000 gallon pond for up to 3 months.
The special mix of bacteria in Control Green Water helps reduce nitrate and phosphate levels, aid the break-down of bottom sludge and odours, as well as helping to make the water less murky.
It also contains barley straw which can further inhibit the growth of the algae that turn the water green, thanks to microbes that consume algae boosting nutrients.
