Controlling green water & blanket weed

摘要

Controlling green water and blanket weed can be tricky if not handled carefully. Blanketweed is sometimes seen as a hard water problem - unfortunately this might lead some people into trying to soften or acidify their pond water. In my view, this isan unsafe 'pond fish' practice and one to be avoided. Pond fish should be kept in alkaline water with a pH about 7.5.
