To baffle or not to baffle?

[lastlight]

If I'm filling my 5g bucket with ro/di with my membranes etc as is right now the rest I can get out of my membrane is about 7 TDS before resin.

Now that I fill a 45g tank every couple weeks it runs for many hours and eventually goes as low as 2 TDS pre-resin so that helps.

I also see TDS creep after having the water turned off for even 10 min. Since I started bypassing water until the TDS goes down I have made my very first portion of resin last since I got back into the hobby.
