Jay Posted September 29, 2010 Share Posted September 29, 2010 Like the title says.....whats your waters ppm after the ro filter but before the DI resins have filtered it? I want to know because mine is 16 ppm and was wondering if my membrane is bad? By the way.....my aquarium is still for sale and has been reduced another hundred twentyfive bucks to $525. whoever gets this also gets the rest of my powerheads and misc crap thats left in a bucket....(like that's really incentive right...but the cash reduction is) Kinda a duel purpose thread Jay Quote Link to comment Share on other sites More sharing options...
