I haven't had much good luck using Jungle products medications. They just don't seem to be strong enough, and they don't say the # mg's each recommended dosage (1 teas.) is suppose to contain. A few other websites said oxytetracycline is the only thing that really truly works against septicemia, so I am trying to locate some. Jehmco has some, but is large amounts and same with fishyfarmacy (with a min. $25 order). Since I have them in a hospital tank, I don't think I would need that much and don't want too much on hand or it will expire before I can use it.
