tds readings

[georgiadawg]

How high to you let your tds readings get before you change your RO/DI filiters?

Good question. I change mine out when it gets to 3-4 TDS. Everyone will have different opinions and im curious to see how high others let theirs get before changing them out.

I do not like anything above 0 and replace filters when it gets above 0
