Hi all, Just bought Diana Walstad's new book and must say I'm sorta shocked. In it, she advocates nearly NO water changes and says she changes the water in her tanks oh, about once every six months. While I'm used to conflicting advice and methods in aquaria, the one thing that has seemed to be a hard-and-fast rule is frequent water changes. Is anyone using her methods? -- Amy amyh at atl_mediaone.net
