There are couple of factors... even if you don't get a BRS system they still have great videos on RODI watch this one for knowing when to replace the cartridges. I spent a lot of time researching before I jumped in. In the long run though this has saved me trips to the LFS and some dollarsOk so I can’t thank everyone enough here but all of this info leads me one more direction. Once I have the system how do I know to replace the cartridges is it from the tds meter?
