Pond Equaliser
From £15.95
Unit price perPond Equaliser
From £15.95
Unit price perPond Equaliser is a natural solution designed to stabilise the water parameters in your pond, ensuring a safe environment for its inhabitants. By balancing the pH levels, it maintains them between 7.5 and 8.5 while also raising the KH (carbonate hardness) to above 5 if necessary. The inclusion of calcium in Pond Equaliser helps remove toxic heavy metals and ammonia from the water, both of which can affect pH levels and pose a threat to fish health.
One of the key advantages of Pond Equaliser is that it eliminates the need for a test kit. Simply scatter the product over the surface of the water three times a year, and it will automatically buffer the pH. Unlike other pond pH treatments, Pond Equaliser ensures that the pH remains stable, even during changes in acidity or alkalinity. If your pond is affected by acidic rain, which can cause pH crashes, Pond Equaliser will counteract this and keep the pH level steady between 7.5 and 8.5 for up to four months after application.

Pond Klear
From £11.95
Unit price perPond Klear
From £11.95

Sludge Klear
From £12.95
Unit price perSludge Klear
From £12.95
Unit price perSludge 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.

This treatment is suitable for both filtered and unfiltered ponds, though it may take a bit longer to show results in unfiltered ponds as the bacteria have more work to do.

Nitrate Klear
From £13.95
Unit price perNitrate Klear
From £13.95
Unit price perNitrate Klear is a safe and effective solution for reducing potentially harmful nitrate levels in your pond. High nitrate levels can lead to problems like green water and algae growth, as algae use nitrates as a food source. Nitrate Klear contains bacteria sourced from natural water environments, which mimic the natural processes in your pond or aquarium. These bacteria complement the nitrogen cycle, a vital process in all ponds, by breaking down ammonia released from fish waste. As the ammonia decomposes, it turns into nitrites and then nitrates, which are then targeted and broken down by the bacteria, gradually reducing nitrate levels and improving water quality.
Nitrate Klear can be used as a one-time treatment to lower nitrate levels or as an ongoing solution to maintain low nitrate levels and promote a healthy pond environment.

Pond Test Strips

For a healthy pond, pH levels should be between 7.5 and 8.5, KH levels between 6 and 10 dKH, GH levels between 3 and 15 DH, Nitrites should remain under 0.5ppm, and Nitrates should be kept below 25ppm.
