TDS Meter woes

[ArnoldosAquariums]

My TDS meter kept reading error on IN and 0 out. . I took it apart and cleaned it and read 2 in and 0 out. Cool! Did it again, so I’m assuming maybe the carbon and sediment needed changing. I got 0 chlorine readings, but it’s cheap to change.

Now it’s reading 1 in and 1 out. I have the 6 stage filter and just changed the At, Cat, and the pro mix not too long ago.

Color hasn’t really changed dramatically.

What gives? TDS meter bad?

Have you changed the battery to see fi you still get the errors?

Change battery but are you sure the probes are correct. The prongs sit a particular way in the flow. If not right they will read real low or give error signal.

probes were pre-installed. Def will try new batteries. It’s been 2 years.. maybe?
