Hey guys, loving the switch from the BRS filters... However, my first cartridge has turned brown already, and I'm unsure at what point I want to change out the sediment filter and carbon block... the TDS still shows less than 4 on the RO end... so do I let them do their thing until TDS rises?

-Thank you!
