TDS meters- useful for FW?

[Cactuspixie]

Can TDS meters serve a purpose in freshwater aquariums, or do they have no value at all outside of salt/brackish setups?

Really? How would you use it?
I have one (late night eBaying a year ago )
But I haven't used it since I got it. I tried keeping shrimp a few months back, but slowly but surely they all died
I impulsively bought some more at an auction the other night
If this meter can help me to meet their needs, then I will be able to justify the hundred something dollars I spent on it

I have not raised shrimp myself, but most people start with RODI water, then add tap water back in to achieve a TDS range of 120-160ppm.

I use a inline tds meter on my FW tank just to test my new water

I don't see the point in testing the tank water as the tank water is only as good as the water you are adding
