Rodi questions?

[Mattl22]

So I just swapped out my pre and carbon filter on my Rodi and my tds actually went up so I let it run an hour and tested again it's was about 9
Does tds change after water sits for a day or 2 I'm getting lower readings after a day ?
Should I bite the bullet and but a new membrane and a new DI resin of just try new risin first?

no the TDs won't go down by sitting a day or two...if you ran it for an hour about 5-6 gallons and still reading a high number the membrane might be shot..test it before and after the DI chamber if the number doesn't go down the DI might be exhausted too....what micron ratings are the filters?
