NT Labs Pond Aquaclear Algae & Blanketweed Control (500ml Treats 28,400L)

【BLUE DYE】: Aquaclear uses a long lasting blue dye which restricts the light from the sun penetrating through the water column therefore cutting off the light source which causes algae and blanket weed to grow in ponds and water features. 【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. Shake bottle well, mix the correct dose in a clean bucket of pond water, then pour evenly around the pond. 【CAN BE USED MONTHLY】: For complete control repeated additions should be made monthly as the colour fades. Water becomes a subtle blue colour and leaves your pond plants unharmed. 【IDEAL FOR USE IN THE SPRING】: For best results use in spring before the algae becomes too established or use Magiclear first to clarify the water. 【PET AND WILDLIFE SAFE】: Aquaclear is harmless to all other forms of life in the pond. [ MADE IN BRITAIN ] : Proudly formulated and manufactured in the UK to strict quality, environmental and safety standards, delivering exceptional product reliability you can trust.
