The Micronizer needs to be installed after the CSV. Then the most pressure it will see is the 65 or so as you said, which I don’t think will hurt the Micronizer. You may need to shut the pump off at more like 63 PSI with that size tank. Basically you want to be running something small like the kitchen sink, get the pressure to steady out at 60 PSI, then shut off the kitchen sink. After the pump has been filling the tank for about one minute, that is the pressure where the pump needs to shut off, probably about 63 PSI.
Now the pressure switch is set at about 43/63 with the CSV160. When you first turn on some water, the pressure will drop from 63 to 43 as the tank empties and the pump will start at 43 PSI. The CSV will have no effect until the pressure reaches 60 PSI. So the Micronizer is adding air to the full volume filling the tank. If you still have something small running like a 3 GPM shower, the CSV will start regulating the output of the pump to 3 GPM and maintain 60 PSI constant for as long as you are in the shower. This is too low a flow rate for the Micronizer to be injecting any air. But with an air over water style tank, the water should flow into the tank from one side and flow out the other side. This way, the water still passes through the tank, which is still about 2/3rds full of air. Even though the Micronizer is not injecting any air at the 3 GPM shower rate, the water is still passing through the tank, which does have air in it.
If you ran nothing but a 3 GPM sprinkler in the yard for days at a time, the air in the tank will eventually mix with and go out with the water, and the tank would become waterlogged. But if you open up more than 5 GPM, the Micronizer adds air the whole time and the tank still gets its air charge as it should. When just using water in the house, the pump will cycle on and off enough to maintain the air charge that is needed.
The air injector with the big tank will allow you to keep the air volume as needed. The CSV will still give you the constant 60 PSI for long term uses of water. The only drawback it that you still have to wait a few minutes for the 25 gallons in the tank to be used up as the pressure continually drops form 63 to 43, before the pump starts, the tank refills, then the CSV will maintain 60 PSI constant until you stop using water.
