If I bought a 450 system how often would I ha e to change the membranes? I think they are 3 150 membranes. So would I have to rotate them as I do now with a double Di system ?No. The pre-filters job is to remove bits of debris that may harm the membrane, they don't bring the TDS down.
I agree with @Part Timer to be honest mate, if you intend to remain partially trad the savings will be negligible and probably not worth your time making the switch. If you plan to grow of course then 100% worth the time and effort.
