TDS is now higher after changing filters/resin on BRS 4 Stage 75gpd system

[erm0715]

Replaced the 2 filters and resin on 4 stage today. Was reading 2ppm TDS prior to change. I've ran ~12g now with the new filter media and it's consistently 5ppm TDS. RODI line output is significantly faster right now. I did not change the DI membrane.

Any thoughts or just continue to flow water through it. It started higher but seems to have landed on 5ppm for the last hour or so.

Thanks!

Should be 0. When was last membrane replacement?
