NT Labs Cristalclear Duckweed Control 250ml

NT Labs Cristalclear Duckweed Control is a pond treatment that removes phosphate from the water to help prevent duckweed from building up. It suits pond keepers who want to stop duckweed spreading across the surface without harming their plants or wildlife. This 250 ml treatment covers up to 4,550 litres of pond water.

Key Benefits

• Removes phosphate from pond water, the nutrient responsible for the rapid spread of duckweed
• Helps prevent duckweed build-up rather than leaving it to take over
• Plant and wildlife friendly
• Easy to use, with a simple weekly then fortnightly routine

How to Use

Add Cristalclear to the pond every week for the first 2 weeks. After that, add it every other week for the rest of the growing season to get the best results. Because it works by limiting phosphate, regular treatment through the season is what keeps duckweed from getting a foothold.

• Weeks 1 and 2: one dose each week
• Thereafter: one dose every other week during the growing season
