Let me start by saying, I'm not drinking the cool aid about Nature 2. I bought this house in 2013 with the pool - didn't know anything. Replaced the Nature 2 in spring 2014, found this site about the same time and quit going to the pool store. I have learned my lesson about letting the chlorine fall too low the hard way. So, I want to get rid of them and know that it will be pretty easy.
My pressure gauge starts off at about 27 psi after a backwash and I think that is too high.
If I remove these two Nature 2's should my pressure go down? How much water actually goes through the Nature 2's? Some or all of it?
