Question
dear Brigitte,i just purchased a pond from a friend and i cannot seem to keep the water from turning green once the rain water hits it. what can i do from stopping this annoying task?

Answer
Hello Tammil!
Algae in ponds is a very lengthy subject, much too involved to answer quickly here.
I can steer you toward a free resource, though, that should be able to help you eliminate the problem.
Just go to www.pondmarket.com and download the following, free, ebook: "Basic Pond Maintenance".
It deals with the subject in detail (the site also has some information regarding it in the "Information Pages".

Best regards
Brigitte
