I have a 3-stage RO plus add on dual DI canisters. What should I put in the first three. I'm assuming a sediment filter and a carbon filter...but what else and what sizes for each? Would like to place my order from BRS today 
Possibly a 5 micron sediment as the first stage then a 1 micron carbon for the second and ? for third?
I'm only getting 40psi on the unit now so I'd like to try and avoid anything that will drop the pressure anymore.
