NT Labs Pond Magiclear, Clears Green and Cloudy Water, Control Against Algae Build up, Improves Pond Water Quality, Pond Water Flocculant (1000ml - Treats 18,200L)
NT Labs

NT Labs Pond Magiclear, Clears Green and Cloudy Water, Control Against Algae Build up, Improves Pond Water Quality, Pond Water Flocculant (1000ml - Treats 18,200L)

Key Highlights
  • Clears green, cloudy water.
  • Easy to use.
  • Suitable for all ponds.
Main Highlights
  • 【CLEARS GREEN AND CLOUDY POND WATER】: Use when water appears green and/or cloudy. Magiclear causes particles in the water to clump together which can then easily settle out of suspension or be removed by the filter.
  • 【EASY TO USE】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. Test the pH and KH of the water (Do not use if the KH is below 6 or the pH is below 7). Aerate pond well e.g. fountain, waterfall or air pump. Conduct a partial water change (as much as is practical) before use, especially if the water is extremely green, like “pea soup”. Switch off pump only if strong flow rate could prevent particles from clumping but remember to switch back on as soon as water clarifies.
  • 【SUITABLE FOR USE WITH A FILTERLESS POND】: Without a filter, some clumps may float and can then be removed using a net. Use when you have plenty of time to observe the fish and take action in the unlikely event of a reaction.
  • 【POND WATER FLOCCULANT】: Magiclear is a flocculant, meaning it causes particles to clump together. Follow with a dose of NT Labs Sludgeclear to clear any excess sludge which may settle at the bottom of your pond
  • 【SUITABLE FOR ALL POND KEEPERS】:The ease of use of Pond Magiclear means it is perfect for use by beginners and seasoned pond keepers alike.
