Pond Klear – The Pond Algae Treatment Revolution

Envii Pond Klear is a pond algae treatment designed to remove the organics that cause algae-based problems like green water. While water treatments like this have been round for years, Pond Klear has one huge unique advantage.

It works in temperatures as low as 4°C.

Which means owners can treat their ponds throughout the year and stay on top of algae. Traditional water treatments only work as low as 10-12°C – according to Met Office data for 2015 – which gives you around only 5 months of the year where it will have any effect.

In this article we’re going to explain why low temperature activity is so important for pond owners and how it will revolutionise the way you treat your pond forever.


Why do ponds go green?

Your pond is naturally full of organic matter.

Whether it’s the twigs from overhanging trees, droppings from an unwelcome pigeon or a beloved koi’s bodily functions, every pond is full of organic material that will decay. This process of decay introduces substances such as phosphorous, ammonia and hydrogen sulphide into the pond water.

Small amounts are fine, in fact, they’re normal, but too much and they can easily affect water quality and the health of your fish. We call this the “organic loading” of a pond. The more organics, the more decay, the more adverse effects on water quality.

Bacterial pond treatments work by introducing beneficial bacteria that clear up or reduce things like nitrites, nitrates, phosphorous and ammonia. All of these things are basically food for algae, so, by reducing or removing them, the algae will disappear.

Organic matter will decay at anything above 6°C which means that for the majority of the year, the organics are decaying and the levels of phosphorous, ammonia etc are rising. Due to fact that pond treatments only work above 10-12°C there is a large gap where the problem will worsen without any way of combating it.



Envii’s low-temperature strains.

Alongside our partners in the USA, we have discovered and developed a strain of bacteria that works as low as 4°C. It was sampled from a stream in Pennsylvania which means that, because its natural environment is water, it is perfect for a water-based bacterial treatment. It works in much the same way as traditional water-treatments in that it reduces levels of harmful substances which feed algae. However, because it works at a temperature lower than organic matter can decay, it can not only stop the problem but it can prevent it.

What is Pond Klear?

Pond Klear is our flagship water-treatment that is designed specifically for use in Koi and garden ponds. It incorporates the low-temperature strain which means it is the first all-year round algae treatment.  What this means for pond owners is that, rather than waiting for your pond to go green and become full of sludge and algae, you can treat constantly throughout the year. By doing this the pond will become established with beneficial bacteria so that when organic matter decays the harmful substances are removed immediately. Pond Klear can be used as a one-off treatment to get your pond crystal clear but we recommend keeping the pond topped up with bacteria.


A few tips to get the most out of Pond Klear.

We always advise our customers that you should clean out your filters before using Pond Klear. This is because the bacteria will loosen a lot of solid organic matter which will be pulled through the filter. If the filter gets clogged, the water will simply run over the top of the filter medium and will therefore become ineffective. It’s also worth mentioning that you should continue to clean your filters regularly whilst using any bacteria product as they’ll clog up much faster. Also, don’t forget to turn any UV lights off before using Pond Klear. UV light kills both good and bad bacteria indiscriminately so the product won’t work until they’re turned off.

When you start using Pond Klear, make sure to use a double or even triple dose to get things moving. Bacteria grows logarithmically (1 becomes 2, 2 become 4, 4 become 8 etc.) so the more you put in at the start the quicker your pond will become established with beneficial bacteria. This has no adverse affect on fish as the bacteria are naturally occurring and fish safe!

It’s always worth remembering that Pond Klear isn’t a “miracle” solution. It won’t clear green water overnight like some chemical water treatments can but it will go to the source of these issues and actually fix them. You need to persist with it and have a bit of patience while the ‘good’ bacteria start to dominate the pond environment. Think of it as part of your pond maintenance regime rather than something to quickly fix a problem.

Pond Klear is much more than just another pond algae treatment. By digesting organic matter at such a low temperature, pond owners can treat much later into the autumn and earlier in the spring. This means that no more will pond lovers be welcomed by a green pond full of sludge in the spring when they just want to sit back and enjoy it. Pond water doesn’t have to be a problem, it just needs the right treatment.
