Established Tank TDS value?

[Putt]

Just wondering; What the average TDS value is of an established reef tank that has always used RO/DI water.

Thanks,

Putt

TDS value of the tank itself? That's pretty much impossible to determine as TDS is a measure for your RO/DI water before anything is added to it.

I'm so sure that the TDS value of a reef tank would/could vary day to day that the number would be all over the place. I have never heard of anyone testing their TDS in their tank.
