Eco-Sure Pond Clear by Envii helps suppress algae growth by removing the nutrients algae requires to flourish.
Why your pond goes green
Floating green scum, blanketweed and silkweed are the most common types of green algae. Green algae needs nitrates to grow; if you have a lot of green algae you have a lot of nitrates in your water.
What causes nitrates in your pond
Nitrates come about from several factors;
When ponds are in full sun and have little shade
When there are too many nutrients from fertiliser run-off, overfeeding of fish, falling leaves and animal waste
What does EcoSure Pond Clear by Envii do to nitrates?
The bacteria in EcoSure Pond Clear by Envii digests and absorbs organic matter from the surface, the sides and the bottom of your pond.
With no organic matter, nothing converts to nitrates and with no nitrates all green algae dies.
Here's what you do
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 whole surface of the pond.
How long can you 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, and how green your pond is to start with.
For quicker results
- Don't feed fish during the summer
- Ensure pondwater is 4°C or above
- Provide shade to the pond surface
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 5g three months later or the following spring.
EcoSure Pond Clear by Envii's long shelf life means it can be stored in a cool well-aired place for up to twelve months later.
More tips for on-going good pond health
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 by Envii to work is over 4°C. In colder temperatures it will continue to work although it may take longer for visible effect.
