I just replaced all my containers, ro membrane and fresh Di. Getting 9-12 ppm at the faucet and 5-9 from the DI. I'm very confused on why these numbers aren't lower.

Tap water is 209 ppm using a digital tds meter.

Running a BRS drinking and reef system unit. 75gpd

Sediment filter new
5 micron CTO/2 carbon block new
0.6 micron +1 carbon block new
RO membrane New
Di new and packed tight.
Running 2 chlorine taste and odor reduction canisters, both not new.

Not sure my pressure coming in.
