I contacted my local pond store this week to purchase a "Barley Bag" to help
control string algae.
I was told that he stopped selling "Barley Bags" and instead he is
recommending a Natural Barley Extract in liquid form. It is manufactured by
Savio Engineering Inc.
It says in the bottle that it is harmless for all plants and fish & contains
no herbicides or synthetic chemicals. The ingredients listed are natural
extract of barley straw, period.
Has anyone had any experience with using this produce to control string
algae and if so what are your thoughts?
