Richyrich...Thanks for the heads up on physan, just picked some up and was looking at the usage rates, you say 1ml per 10 gallons? is that for the res and to do while the system is running? I am planning on doing some dips and spot treatment at the rate of 1 tsp per gallon(the recomended rate on the bottle for full emmersion) which is about 5 ml.
What is your personal experience with different concentrations and what was the initial problems?
