I ordered the Dow Chemical 100GPD (98% rejection rate) membrane from bulk reef supply: https://www.bulkreefsupply.com/100-gpd-membrane-dow-filmtec.html
It came today. (Along with the prepackaged di resin from BRS)
My tap water TDS is 178ppm.
(My sediment and carbon blocks were changed 2 weeks ago, rinsed, and hardly used).
After running the new membrane for almost 30 min, the initial tds went from 8ppm to 11ppm.
Before anyone asks, I even changed my inline tds monitors a few weeks ago because they were old, and I questioned the readings.
Is it normal that my tds readings after the membrane are still pretty high? The pressure going into the membrane is 80psi with my booster pump (I always use my booster pump).
