Garden pond 'crystal clear in five days' as £16 fish friendly treatment praised

With the arrival of summer, people are heading outside to get the garden sorted for warm weather. Those with a pond in their garden may find the colder months have caused the water to go green and murky, but there's a relatively quick £15.95 solution to this problem that home gardeners swear by.

The Envii Pond Klear treatment has excellent reviews, with more than 8,500 people giving it an overall score of four out of five at Amazon. This retailer is currently the cheapest place we can find the treatment, with a one-litre bottle (enough for 40,000 litres of pond), priced at £15.95 and undercutting B&Q and the Envii website.

Safe for all fish and wildlife and with no harsh chemicals, the natural Pond Klear suppresses the growth of new blanket weeds and the brand claims that after eight weeks of use, the pond water should be clear. Many shoppers confirm this, with one person saying it takes even less time than this: "No chemicals. But works brilliantly. Crystal clear in only 5 days from treating. Defo buy again."

Someone else agreed, writing: "Great product, follow instructions properly, clean filter before using product. Three days in and I've already seen a huge difference in water clarity and fish look more vibrant for it. Would recommend."

To use the Pond Klear, add 25ml per 1,000 litres into a bucket of pond water. Stir thoroughly and spread evenly around the pond. Reapply every seven days using the same application method.

After doing so, people have reported 'happier goldfish', such as this person, who said: "Makes a big difference. We have re-ordered."

Customers note that it does require some patience, which could be frustrating. One person took some stars off their review and said: "Appears to take several weeks to clear."

Someone else said: "Do not expect the pond to clear overnight. Have patience. I put my first amount in five days ago." And another customer shared: "Perfect product and easy to use. Works well if you have the patience to wait for water clarity."

There are other pond water clearing treatments on the market, such as the Blooming Fast Pond Clear Pro 2 Step. An extra-large pack (treating 60,000 litres) is stocked at You Garden for £29.94. Another option is the Evolution Aqua Pure Pond Bomb, with a £14.95 pot treating up to 20,000 litres. It's easy to use as the entire contents of the pot is simply dropped directly into the pond.

As well as helping make the water clearer, so people can enjoy seeing fish and other wildlife in the pond, Envii Pond Klear treatment benefits fish by removing phosphates and replenishing good bacteria. The treatment can be used for all seasons, not just summer, and can work efficiently at temperatures as low as 4 degrees celcius.

This means people can maintain a clear, healthy pond through all the months, without needing to switch products seasonally. To clear algae, it works by clumping these particles together and causing them to sink to the bottom of the pond where they can be broken down by beneficial bacteria.

The product clears existing green, algae-filled water, as well as preventing new outbreaks by maintaining a biologically balanced pond environment. A happy customer noted: "I had a very green pond. After treating for 8 weeks, it's almost completely clear. Very impressed with the product."

Another person explained: "After disturbing my pond and replacing the pump, the water was terribly murky. I was cleaning the pond filter almost daily, but the water remained murky. In desperation, I tried this product and waited for results. I waited for a week, no improvement. I added another dose and waited. Then the water started to clear!

"I added a third dose and, lo and behold, the water really started to improve. After three to four weeks, the water is now crystal clear, and I can see the bottom of the pool, the fish, and all the oxygenating plants.

"I propose to keep adding a maintenance dose on a weekly basis. This is definitely “the best thing since sliced bread” and I recommend it."
