The long term cure... Installing a biological filter and Ultra Violet Clarifier system and establishing a good selection of plants to digest the excess nutrients will both assist in the reduction.

Short term... If it is a new pond that has not yet balanced, there are a number of products available, which will reduce green water. It is recommended, if you have a planted pond, to use an environmentally friendly treatment that will not hinder the growth of your plants.

Even established ponds go green occasionally... In certain conditions these ponds can go green due to a number of reasons, such as high sunlight levels in early spring before plants have established themselves. Either install an ultra violet clarifier or use treatments on a short-term basis.

BLANKET WEED... Is a real nuisance, like a green, slimy, candy floss – it can rapidly take over should there be enough nutrients and sunlight for it to thrive on. So again, a mature well-balanced pond will suffer less.

Mechanical Removal

If you have a major blanket weed problem it is best to remove as much as possible by hand before starting any treatment. If the worst of the blanket weed is not removed it will breakdown and pollute the water causing serious water quality problems, which could effect your pond inhabitants.

Tips On Avioding Algae

• New ponds should be heavily planted.
• Try to have up to two thirds of the pond surface covered with plants.
• Avoid over feeding fish & remove excess food.
• Install and maintain an Ultra Violet Clarifier.
• Successful control needs to start before the algae takes hold. Therefore consider starting treatment in early spring.
• Avoid changing the pond water... This introduces fresh nutrients for the algae to thrive on.
• Always remove as much blanket weed physically, before treatment
