I agree with Mike. I really don't like to do treatment unless there is a problem. I just killed one of my best Maruyama kohaku by overdosing Superverm. This kohaku I just bought recently for the Orlando Young Koi show. The fish looked healthy in my QT. However, I treated Superverm just for prevention. I read the instruction on doses 1ml for 100gal. My QT is about 800gal and I filled half of water which equates to 400gal. So I should use 4ml or 4cc to treat. I got my syringe with mark as CC and OZ. There is 60CC and 2 OZ volume for the syringe. By mistaken, I thought this is a 2CC syringe, and I used the 2 full syringes of SuperVerm on my QT. I actually did 100times the doses

. When I found out, it was too late. My fish was gone.
