| since you have all in quarantine tank, as well just do a shotgun treatment. proform c 1.5 dose in 3 days, then supaverm in 2 dose in day1 and day 3 keep it in the quarantine tank for at least 4 weeks. meanwhile drain the pond, let it completely dry in couple days. Costia can resist dry when in low temperature form a cyst, in your temp, it not likely going to happen. touch the fish, with costia you will feel soft. Formalin and malachite show more effective than just formalin alone. For my experience, as you can see, a shotgun treatment most likely will save more fish (particular the small one) than a scope. scope may miss something, but shotgun don't. Chloramine T come from Chlorine, the main ingredient in our tap water. is effective but again, it stays in water in about a day. Formalin is also just 12 hours in the water, malachite green stay for month, even it discolored by the sun. The only thing salt can kill now is Chilo, but it have to be 6%. Cross your finger, after a shotgun, if you still have some by then, you be allright. |
