I can see this threads been inactive for a while but after reading it several times I'm ready to build my autodosing system and I have an idea that has not been discussed. I have a large tank (300 gallons) and I want to mix enough for at least 4 weeks. My idea is to use a 5 gallon cornelius keg (soda keg we use for brewing) and hook up a regulator with a solenoid controlled by a timer. The advantage of having a completely sealed container is that I can push the liquid out with an inert gas (nitrogen). The question is, when mixing and storing the solution, what effect does oxygen have on the degradation/mold growth and can that be countered by purging the container of oxygen?

I'll be using the keg idea regardless as I have a large tank to dose.
