    Just curious as to what others' are running for RO/DI.
    I'm getting ready to replace all filters but my membrane as well as add a 4th.
    My current setup is 5 micron sediment, 1 micron carbon, membrane & DI resin.  N. Liberty water seems to be terrible @ >= 1,000 on my TDS meter so I'm adding an additional stage.
    My assumption is that the water has tons of small versus large particles, and 2 online vendors have different suggestions:
    Bulk Reef Supply:
    5 micron sediment
    5 micron carbon
    1 micron carbon
    Air, Water & Ice:
    10 micron sediment
    5 micron carbon
    1 micron carbon
    Leaning towards the 10-5-1...
    Thoughts?

    I run the 10-5-1 just because we have a ton of iron in our water and I have noticed the 5 micron sediment filters clog a lot faster and need to be changed more often.

    I do 10-5-1 - the 10 does seem to catch a lot of junk here (looks mostly like iron/rust) that I think would clog the 5 quickly...
