RO DI install question/confirmation.

10 microns is way too coarse to protect the pores in the carbon from plugging and fouling. Did you know you can see 40 microns with the unaided human eye? I along with most of the reef RO/DI vendors recommend no larger than a 1 micron sediment filter so it protects the 1 micron or smaller single carbon block so it can do its job of removing chlorine and in the case of chloramines not only removing the chlorine portion but also breaking the bond with the ammonia so the RO and DI can remove it.
Always place the sediment filter or both sediment and carbon in front of the booster pump so it is protected from silt and particulates.
Take a look at this diagram to get an idea:

That makes perfect sense. I wonder why they sent a 10µm filter? A bit frustrating b/c I wanted to improve my system, not handicap it. Thanks (again) D.R. I'll order a the spectrapure filter. In fact, I may just replace as many filters as I can w/sp filters.
