Use Green Water Beaters by adding the water soluble sachets to your pond, then allow the formulation with pond-friendly bio bacteria to get to work over the week.
Each pack contains 6 water soluble sachets (each sachet treats 4500 litres/1000 gallons for up to a week)
Use Pond Cleaning Treatments with Friendly Bio Bacteria
Formulation contains pond-friendly bio bacteria, just add those happy bacteria in to your pond and let them do the work, no need to feel guilty its what they love!
Use in your pond from early spring when water temperature is above 10 degrees centigrade.
Green Water Beaters have been tried and tested in thousands of Garden Ponds over years and they really do work!
Had some trouble with Green Water in my pond in around June it looked really awful and smelled a bit too!, slowly added the sachets and it really helped clean the pond water up, by the end of June beginning of July I had fairly clear water at least it wasn't green anymore! Spoke to Nath at powerbee who advised that I should also add some oxygen so got one of the air pumps from https://www.powerbee.co.uk/solar-air-pumps.html
this seemd to also help, also got some plants on top so hopefully should stay clear now
