Frequently Asked Questions
How often do I need to dose my pond?
How often do I need to dose my pond?
Apply one dose a week until the blanket weed has gone, which usually takes around three weeks, though some ponds need one or two extra doses. After that, dose once a month to help keep it from returning.
How much powder do I need for my pond?
How much powder do I need for my pond?
Use 30 grams (one scoop) per 900 litres (198 gallons) of pond water per dose. A larger pond needs proportionally more; for example, a 4,500 litre pond needs five scoops (150g) per dose.
Will it still work in cold weather?
Will it still work in cold weather?
Treatment efficiency is reduced when water temperature drops below 8 degrees Celsius, so dosing in colder conditions may take longer to show results.
Which pack size should I choose?
Which pack size should I choose?
The 1000g pack is rated for ponds up to 10,000 litres and the 2500g pack for up to 25,000 litres. The 400g pack is the smallest option; use the dosage guide to work out roughly how many treatments it will give for your pond's volume.
A pond powder treatment that keeps blanket weed from clogging your filter, pump and pipework, suited to ornamental and garden ponds of any size. Weekly dosing clears established weed in around three weeks, and a lighter monthly dose then helps stop it coming back.
Stop Blanketweed is a powder treatment formulated specifically for filamentous algae, the stringy blanket weed that fouls ponds and chokes up filters, pumps and pipework. It's designed for ornamental and garden ponds and helps restore clear water once the weed has taken hold.
Blanket weed is one of the more persistent problems in pond keeping: left alone, it turns water murky and clogs equipment. Dosed correctly, this treatment eradicates it over a few weeks, and a reduced monthly dose afterwards helps keep it from returning.
What you get is Stop Blanketweed powder in your chosen pack size: 400g, 1000g or 2500g. The 1000g pack is rated to treat ponds up to 10,000 litres (2,200 gallons) and the 2500g pack up to 25,000 litres (5,500 gallons); the 400g pack is the smallest option and suits smaller ponds, with dosing following the same rate of 30 grams per 900 litres regardless of which size you buy. You'll need your own clean container to mix the powder with pond water before applying it, as this isn't supplied.
Dosing is weekly until the blanket weed clears, which usually takes around three weeks, with some ponds needing one or two extra doses. After that, a single monthly dose is enough to stop it coming back, though treatment works more slowly in water below 8 degrees Celsius.
