Hi all. After the last message on barley straw, I figured it would be appropriate to post a message on GreenClean Granular Algaecide.
One of the theories behind barley straw is that, as it decomposes, it releases hydrogen peroxide which can act as an algaecide. GreenClean is an EPA registered algaecide, and the active ingredient is a peroxygen chemistry - all of the action, without all the messy hay!
GreenClean biodegrades into water and oxygen as it oxidizes the algae (no build up in pond), will not harm plants, and testing has shown that it is non-hazardous to fish (including sensitive species such as trout) at over double the highest labeled rate.
To treat a 3/4 acre pond with an average depth of 4 feet (3 acre-feet), here is what I would suggest...
GreenClean PRO formula:
Curative (full bloom): 250lbs (approx. 90lbs/a-f)
Preventative: 25lbs (approx. 9lbs/a-f) 1x/month
Hope this offers another solution to your problems! Feel free to call with any questions.
