Gidday Everyone...

I have a Culligan Iron remover with the air injection after the pump.
Are the ones with the air injection at the head of the media tank equivalent????

I know mine sludge everything after the Micronizer, specially the valve on the media tank, so I wonder if the head type does that also???

My other dilemma is that with the micronizer, a CSV valve for constant pressure 50Psi would not work to well as with one tap open (1.4GPM) the micronizer would not introduce air .

So, does the air injection at the head works with less flow?????
