EZ TDS Meter… accurate?

[rja]

Hey folks,
I have been getting my RODI water for a few different LFS. Recently got this “EZ TDS” meter off Amazon for $15

Anyway, I got ATO water today from a trusted LFS that’s full of great looking show tanks…

This meter measured it at 100-110 ppm… Way too high.

Are these things accurate and am I poisoning my reef?

Please help

You can’t make your own RODI ? Only way to be 100% sure is if you are making it and have a TDS meter on the system. Can you ask the LFS to show you their TDS meter while the RODI system is running in the store ?

I keep trying various sinks and spigots in my house, I continue to get leaks under the sinks. I also need to order a better spigot to mur-lok fitting because i cannot get the fitting to seal completely on the spigot.
