Eco Gold is a blend of beneficial bacteria and minerals that will eradicate blanket weed quickly and efficiently.

Eco Gold is a one-off treatment to eradicate blanket weed, where traditional treatments can be very slow. Eco Gold will work every time at all temperatures. Initial applicaction of Eco Gold may cloud your water for up to 7 days.

Once your blanket weed has gone, Kusuri recommend a weekly application of Eco Pure to maintain a weed free pond.

1 kg treats 3000 gal.

Inhibits blanket weed, flocculates particle matter, increases water clarity, degrades sludge.

Eco Pure added weekly will reduce blanket weed by reducing its' food source. Bacteria coat the blanket weed, starving it of food - this will initially break up long strands. Every pond is different! In some ponds Eco Pure can work in 2 weeks, most ponds can take 4 - 8 weeks. Use Eco Pure early in the season - do not wait for it to grow, in other words use it in a regular preventive approach. Use about 50 to 100 grms per 1000 gal.
