Spectrapure Mpdi40 4 Stage RO/DI - 4 Stage - USED - w TDS Meters
Used Spectrapure MPDI-40 (no membrane or filters installed). Includes in-line TDS meter (untested but worked when I last had it running), handheld com100 TDS meter, and an extra CF-1-10 filter. Bought this new back in 2007 and no longer run a reef tank. Was hanging on to it just in case, but don’t think I’ll start one up anytime soon. I think I changed the restrictor to be 60 or 90 GPD but can’t recall. No membrane or filters, aside from the new extra CF filter that was in my storage box. Please ask w any questions!
