Spear & Jackson Greenwater Treatment 2 x 1L - Rapidly Clears Green Water Enhances Mechanical Filtration - Safe for Fish And Wildlife - Treats 20,000 Litres

now tried all of these treatments and I have come to the conclusion that the green stuff in my pond is special... even after an 70% water change adding these products doesn't help.... so I'm going to have to live with itA month later the water seems to be improving!

Seems good product fast post thank you

I purchased this product because I trusted the brand. It had no affect on my pond whatsoever.Very disappointed
