About this item
- 【BLACK DYE】: Black Pond Dye is commonly used by landscape gardeners and uses a safe, economical dye that restricts the light from the sun penetrating the water column, therefore cutting off the light source which causes algae and blanket weed to grow.
- 【PREVENTS GROWTH OF GREEN ALGAE & BLANKETWEED】: Provides a mirror like reflective surface to your pond, water feature or lake and prevents the growth of unsightly green algae and blanket weed.
- 【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.
- 【IDEAL FOR SPRING POND MAINTENANCE】: For best results use in spring before the algae becomes too established or use Magiclear first to clarify the water. For complete control repeated doses should be added monthly as the colour fades.
- 【FISH, PLANT, PET AND WILDLIFE SAFE】: Black Pond Dye 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.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
