How many stage ro unit should i get?

[Biddence]

I am upgrading to a larger system and getting water from the LFS is out of the question now. 8 just purchased a new house and have well water. We had a test done on the water before we moved in which I will post a photo of, the TDS of our water is 138. How many stages should I go with on the new ro 4 5 6 or 7?

My TDS was in the 200’s and I went with a BRS 7 stage. My logic for this and just about anything is, “I rather have it and not need it than to need it and not have it”

sure, you spend a few extra bucks but it’s worth the reassurance

Initially that was my thought process and going with a 7 stage, but I didn't know if it would be overkill or if I would have co2 in my water and have to add another step to the system.
