King British Green Water Control for ponds
King British Green Water Control targets the tiny unicellular algae in your pond that cause "green water". This special additive causes the algae to clump together and fall to the bottom of the pond, where they can be sieved out or where the light levels are too low for them to thrive. "Green Water" is unsightly, can clog filters, and can be bad for fish health, as it can reduce oxygen availability at night. One 250 ml bottle will treat 2,250 litres of pond water.

Available in 250ml

Within the pack is a dosing calculator where you can work out the volume of your pond. Using this information you can then use the table to calculate the dose required. The specially designed bottle then allows you to ‘squeeze’ the measure into the chamber which is then poured into a watering can full of pond water, ensuring the watering can is free from any chemical contaminants. Then slowly empty the watering can into your pond, ideally using a rose attachment. This chamber helps prevent over-dosing and allows full control.

Storage: Do not store above 25°C. Warnings: Store the bottle in the carton provided.
