Got about 5 pills in providence, You will only need 1 to dose the tank and dip anything that you get for quite some time to come. Me personally i dip everything in betadine in fact i have been playing with higher concentrations with good results, all acros, millies,stylos anything branching i use both betadine and interceptor on.
I've safely dipped with up to 8ml of betadine with a staggered dose. For the first 15minutes 5ml to 4 cups of water then i add an additional 3ml for last 15 minutes. I hit them with interceptor for 5 1/2 hours prior adding the betadine to the interceptor.
So far acans, zoos, zoas, montis, stylos, milles, acros, have all had a 100% survival rate even with the higher concentration. I have noticed unwanted guests not evacuating until the second 3ml dose is added. Interceptor seems to also allow for a large margin of error and no ill effects are caused by overdosing save the fact that it can get expensive.
