Which algae control product?

Probably the most common problem in garden ponds is algae which will either be single cell, causing green water, or filamentous, otherwise know as blanket weed.

The water in new ponds will often trun into an unattractive "pea soup" before any planting becomes established.  This is known as New Pond "Syndrome".  Algae spores will thrive on the nutrient-rich tap water often used to fill a pond, at a time when there is little or no competition for these nutrients.

Algae can also be introduced to an established pond in the water used to transport new fish and plants, by birds and in rain or soil, so it's hard to avoid.


Treatment options

Ecopond Extract of Barley Straw is a natural, easy to use and faster acting alternative to the traditional pads, pouches or bales of barley straw.  It acts directly to kill the algae by breaking down the cell wall and used regularly will also inhibit new growth.

Ecopond Barley-bio Algae Control is a natural, microbially based algae control product.  It is particularly effective in controlling blanket weed.  It will kill algae and prevent it from growing by removing the nutrients it needs to survive.
