You may have algae in the tank.

mine goes in at 450, guttered but still comes out a 0.  try a new bag of resin, undo all connection and wash with hot water.  attach a filter from tank to resin.  They are cheap and easy to do a fiver or something from the window cleaning warehouse

Sounds like membranes. They are only working at a 90% efficiency if the figure of 22 is taken before the di vessel.

Changing prefilters won't lower your output tds.
