ro/di unit f'ed

[scuglass]

i hooked up my ro/di unit a couple days ago and it says to flush the carbon and other filters (which i think i did wrong, i think i flushed the water thru all the membranes including the ro and di) and flusshed the tank twice. now when i do tds readings i fill a cup and get like 54 then fill another cup get 25 then another 10 then 5 then 0 wtf is up with that?? is this normal?? also the water at first is really cloudy with bubles i think but then it clears up is this normal??
