Blagdon Clear Pond is a highly effective treatment for cloudy and dirty looking water, or water that is green, brown or grey. Blagdon Clear Pond is harmless to filters and all species of pond fish, plants and water using wildlife. Ponds can often have cloudy water after maintenance, heavy rain or after a new filter or UV clarifier has been fitted. Blagdon Clear Pond is a natural-based flocculent that clumps fine suspended particles together causing them to sink to the bottom of the pond or be removed efficiently by a filter. Cloudy water is caused by tiny particles of waste suspended in your pond’s water. Whilst cloudy water is unlikely to affect the wellbeing of your fish or plants, it is an eye sore and can effect enjoyment of your pond.Add 1 x 25ml measure for every 500 litres (110 gallons) of pond water. We recommend adding Clear Pond to a bucket of water and then distribute this evenly over the pond's surface.Do not overdose as this could cause prolonged brown discolouration.This is a single dose treatment and is safe to re-dose after 5 daysAll Blagdon treatments are designed and manufactured in the UK.
