Should I remove post carbon filter?

[jhaggerty1990]

I have a six stage RODI water filter with a post carbon filter after the membrane and resin. My filtered water is reading 6 TDS. It says the post carb filter can temporarily raise TDS. Should I just remove this?

I don't know what a post DI resin carbon filter is supposed to accomplish. I don't have one but I have seen them used for "taste" in drinking water?

Well, on the canister, it says that it can temporarily increase TDS by a small amount and the reading came out as a 6PPM. Figured I might just remove it and see if it comes out as zero

I would remove that final carbon filter, there should be no need to have anything after the DI canister(s). See what TDS you get that way.

I doubt it matters one way or the other.

The TDS went from six to one so I guess I’ll keep it off

Just remember tds itself is not a concern. Seawater has something like 35,000 ppm tds in it. It’s really just an indicator of whether the ro/di is doing its job removing bad stuff from the tap water. :)
