1 ml per 10 gallons. And don't blast them. Just spread them more I feel. Suck them out . Run the water thru a towel filtering the water. Then put water back in.. I would try kalk. Carbon and light dosing of h202. Along with turning skimmer off. I beat them in 2 weeks with this method. Dynos will start to thin out.
In my case they're already everywhere ^.^
