Ecopond Water Butt Fresh prevents odours and the growth of algae in water butts and tanks.  It contains naturally occurring, beneficial micro-organisms which digest organic matter, keeping stored rain water fresh and helping to prevent algae growth.  Water Butt Fresh will also neutralise potentially harmful soap residues in grey water. It is available in a 500 ml bottle or a 2.5 litre jerry can to provide a cost-effective option for gardeners with several water butts or a large storage tank.

Dosage: 25 ml per 100 litres weekly in rainwater, 50 ml per 100 litres weekly in re-cycled water.
