so i got a handed down 55GPD coralife RO
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
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?
