Don’t Be Green, Let Your Fish Be Seen!

Green water is the most common problem with UK ponds. Made up of millions of microscopic algae spores that cause a green tint to the water. This tint can range from a murky, swamp green, to a vibrant, almost luminescent green. Fortunately, although the problem may look disgusting and daunting, with the help of a green pond water treatment, it is relatively easy to fix and even easier to prevent in the future.

How to Clear Green Pond Water

Pond Klear contains millions of beneficial bacteria that target the microscopic algae spores. Next, they clump them together and digest them, to eliminate the green water. As well as targeting the algae spores directly, Pond Klear will also focus on eliminating the unwanted organics that feed the algae spores. Decaying fish food, leaves and the worst contributor, fish waste are the kind of unwanted organics.

Unwanted organics emit harmful toxins that pose health risks to fish, which is why Pond Klear was developed. By removing toxins from the water, oxygen levels are increased, and as a result fish will become more active and happier.

Pond Klear is the UK’s most trusted green pond water treatment with good reason. Containing innovative bacteria that work down to 4°C. This gives Pond Klear a very unique advantage over other treatments. Most treatments only work down to around 12°C which gives algae a window to sneak in a little extra growth. Algae grows down to temperatures of 8°C, therefore if the bacteria can’t work that low, there is nothing to fight off the algae spores.

Although the main focus is to eliminate green pond water, it also suppresses the growth of blanket weed and algae. However, if you are wanting to get rid of blanket weed, we recommend Blanketweed Klear. For string algae, we recommend Algae Klear Xtra.

For ponds over 20,000 litres, use Pond Klear Xtra which is three times stronger than our standard Pond Klear.

Pond Klear tablets have been designed as a replacement for Unwins EcoSure Pond Clear tablets.

Finally, before using any bacterial treatment, we recommend checking the pH and KH level in your pond, or using Pond Equaliser. This instantly stabilises the water parameters and create the ideal environment for fish and bacteria.
