first SW, some RO/DI questions

so i got a handed down 55GPD coralife RO/DI unit and have since replaced all the membrane, resin, and cartilages. i also have an inline dual TDS meter. i tested the water out of the faucet which register somewhere around 15-20TDS. since this is my first RO/DI unit and first time replace all the important membranes I'm not so sure about the red line (dirty water line).

The water out of the red line is creamy, which is very surprising. when i use my TDS meter, it registers a surprising >100TDS. is this normal? the shot up in TDS and the creamy water?

It happens with new filters you'll need to let them flush, toss the first 100-150 gallons of water

i have heard people recommending throwing away first some-number of gallon of water before but here's my question. my TDS meter registers 0PPM for the purified water, i don't want to throw away useful water. so, should i still throw away this water?

Not if it's reading 0 ppm I'd say the system is flushed The "creamy" waste water could be full of air giving it creamy look.

that's some quick "flushing" because it only took my unit about 10min to flush out the creamy water. as a matter of fact, the TDS reading of the purified water was almost 0PPM instantaneously, as oppose to decrease of PPM over some time. i have tested my TDS meter so there can be nothing wrong with it.

Hey taste it. Pure water is odd tasting. No minerals for flavor.

Seriously though I used mine when it reads 0.

Sounds good I flush out each filter in order for about 3-5 min. Sediment flush then add the carbon flush run some thru the membrane then hookup the di throw out the first two or three gal.
