I always get a LOT of hydras when I start feeding the fry BBS. I have heard there is a product called Bozeman's Goldfish Tonic that is great at killing hydras but won't hurt fry. I can't find this stuff and my LFS said they don't make it anymore. Any thoughts, comments or suggestions would be appreciated.
