Lake Klear is a highly effective water treatment that harnesses the power of billions of beneficial bacteria to target and eliminate the organic matter that algae feed on. By removing the algae's food source, Lake Klear gradually starves the algae while also helping to reduce harmful nitrogen levels in the water. One of the unique features of Lake Klear is its ability to work at temperatures as low as 4°C, making it effective year-round, even during colder months.
This natural solution enhances water clarity by restoring the biological balance in your pond and fostering a healthy, established ecosystem. The beneficial bacteria in Lake Klear also work to control common water issues such as blanket weed, duckweed, and green water, improving the overall health of your lake or pond.

Yes, Lake Klear is a natural product that is safe to use around pets, fish and other wildlife.
No, but it will remove its food source and overtime starve it to death. It will still need to be manually scooped out.
Whilst this can be used all year round, it is most effective when water temperatures are above 4°C.

"It helps to rid my lake of duck weed. It use it every 2 months even in the winter."
"Good service and product"
"Had a bad Blanket Weed problem, but after using this, and then removing the dead weed and administering a maintenance dose, the lake is looking nice and klear!"
"The treatment after 5 days is showing signs of killing off the blanket weed"
"I can not rate this as it needs longer to work than the blanket weed treatment"
"Unfortunately this product did nothing to our pond, although customer service was good, I had to purchase after """"Tap- No more greenwater"""" which sorted it after a week."
"Too early to tell if it works!!!!!"
"So far so good. Totally emptied pond (25,000 gallons) and refilled without fish. This product is keeping the water reasonably clear whilst we try to 'balance' the water with planting, filtration and oxygenating plants."
"Used, too early to judge results"
