Sludge Klear

Natural bacterial pond sludge remover that targets the build-up of unwanted organics at the bottom of your pond. This layer of sludge can sometimes give off unpleasant odours, and contribute to green water and algae growth, so it is important to treat it with bacteria.

Sludge Klear is a natural pond sludge remover that uses millions of beneficial bacteria to break down and target pond sludge. These bacteria work by dislodging the sludge and releasing it into the water column, where your pond filters can catch and remove it. While it is effective in ponds with or without filters, it may take longer to work in ponds without filters since the bacteria are doing all the work.

The bacteria in Sludge Klear are capable of operating at temperatures as low as 4°C, helping to improve the overall health of your pond while removing sludge. It's normal for your pond's water to appear cloudier and murkier before it improves, as the bacteria disturb the sludge, similar to how mud or sand is stirred up in water.

Unlike vacuuming, which removes beneficial bacteria and leaves your pond more vulnerable to future issues, Sludge Klear provides a long-term, natural solution. While using a vacuum may seem faster, it doesn't address the root cause. By taking the time to let Sludge Klear work, you ensure a healthier pond environment with lasting benefits.

  1. Check the pH of the pond water and, if required, use Pond Equaliser
  2. Use one tablet per 5,000 litres of pond water and add to a bucket of pond water
  3. Leave to dissolve for two hours and then stir and add to pond
  4. Reapply every 7 days to keep ponds clear

Reviews

Very successful

"Excellent so far. I have applied three doses so far at about 10 day intervals. I am impressed with the progressively improving water clarity. This is in conjunction with back washing the filter every seven days or so, as I carried out major vegetation removal a couple of months ago which disturbed a vast quantity of sludge. VI Back wash before applying the solution. I hope to reduce the treatment to monthly as we head into autumn and the winter months."
