TDS meter

[Lakeside518]

Does anyone here use a TDS meter on their reef setups for makeup water? Test the RO/DI water?

If so which one do you use?

Whats a good # to have? Less then .02?

I have an inline one I got from Aqua-fx. It just stays hooked right to the unit and measures inlet and outlet TDS. Very handy. Not sure, but I think it was under $25.

Thanks for the help!..

I just ordered a TDS-3

Whats a good test range to have? To strive for besides Zero?..

well IMO if your readings are high say.......500+ like mine were you still should be able to get it pretty close to 0. My readings are between 2-10ppm
