Watch the water of your large pond go from green to clear in weeks and invest in an on-going healthy pond! This non-chemical powder treatment treats 40,000 litre ponds (around 20-30 square metres).

EcoSure Large Pond Clear is a natural solution based on live microbes which eliminate nitrates in the pond, which algae feeds on. This starves the algae that turns the water green, clearing your pond removes high-level nitrates that poison and injure fish and foul the water.

Here's what to do
The best thing to do is check to see if there are excess nitrate levels in your pond with the FREE EcoSure® Pond Clear Aqua Plus Nitrate Testing Kit worth £3.95 with every pack. Instructions are in your pack and it works just like a litmus paper test to test acidity.

If there are nitrates in your pond take the following steps;

Place the powder in 5 litres of pondwater. The higher the temperature the better, so try to do this on a sunny day when the sun has warmed up the water.

Leave for 2-4 hours and give the 5 litre solution a mix. Pour into the pond slowly around the surface of the pond.

How long can I expect to see results
Sometimes it takes up to a few weeks to see results, sometimes it takes longer, depending on water temperature, fish population and weather. Every pond is unique in its composition of nutrients and nitrates which means the time it takes to clear your pond of green algae, blanketweed and scum varies.

After 4-6 weeks, repeat the process above if the green water persists. To maintain a clear pond, apply a further 20g three months later or the following spring.

Eco-Sure® Pond Clear Aqua Plus's long shelf life means it can be stored in a cool well-aired place for up to twelve months later.

Help keep your pond healthy too by introducing lots of pond plants which produce oxygen.

Keep levels of tap water, often high in fluoride and calcium, to a minimum when topping your pond up by using stored rainwater when you can.

Please note: The optimal water temperature for EcoSure® Pond Clear Aqua Plus to work is between 10 & 13°C. In colder temperatures it will continue to work although it may take longer for visible effect.
