I have used Physan 20 before. It's been several years ago but I don't recall being impressed with it as a sterilization agent between grows or as a cure. It doesn't seem to kill pythium spores or disrupt a heavy infestation. It might work well as a preventative though. I would be willing to test it in the cloning trials. If I don't include it in Round 2 I will try to work it into round 3.
I hope you find something that works for you, sounds really frustrating what you're going through.
