You are referring to a Hozon injector. They are consistent enough and very inexpensive. Hummerts carries them www.hummert.com . I use one in a production house. it's not difficult at all, except that you need to keep water in the bucket for the injection fluid. You can inject things like compost tea, fish emulsion, etc. You could use vinegar to reduce your pH because you don't need to drop it much. We have a limestone aquifer that our water is drawn from so pH is high. But if we don't have plants in the greenhouse longer than 8 weeks I don't worry about it unless they are very sensitive. Snapdragons seems to be indicators for me.

 2) Get one of those simple devices that screw between the hydrant and the water hose with a drop tube into a container of liquid fertilizer, acid or whatever else you want to add to the water.  Most of these dispense at about a 1 - 16 ratio and I have heard are not very consistent.
