To baffle or not to baffle?

True dat, but filling a 5g reservoir is different than the half inch change in level in your sump IMO. Then again maybe it just keeps the 5g full and it doesn't completely empty. I dunno, I just heard someone on here talking about it, maybe they'll see this and chime in.

Running small volumes through your unit is hard on the DI resin due to TDS creep. When the unit is shut off the solids will cross the membrane as time goes by and when the unit is turned on this large concentration gets taken out by the DI. I now with my online monitor it will read about 25ppm at the membrane outflow upon startup and then settle to about 2 after a minute or so. I don't know what small volumes does to the membranes tho.
