Duke,
The doc said "Antibiotics don't cause weakness of the immune system". That is a true statement. Note the specific referral to weakness of the immune system. Your's is a true statement also.
Steve,
Have you contacted your supplier for help in this matter? Perhaps he can provide more information if he has experienced this problem or has other customers experiencing this problem.
You might want to consider contacting the State Wildlife Department for help. I think the first step is to identify the disease before treating it. If you have a disease that is not treatable, it will be better to do a complete kill and even perhaps treat the pond with cholorine before the disease spreads. I am glad I do not have a pond downstream of yours....
I know of a super treatment for just about everything but the guys on this site bashed me really hard for mentioning it.
Please keep us informed.
