TDS calibration

[Samw]

I'd like to recalibrate my TDS meter. Anyone got any calibration fluid to sell at the reef meeting?

Hey Sam, I've got some fluid that I bought at a local hydroponics shop, but I'm not sure it's the right one for my meter. Apparently my Hanna TDS meter requires a specific TDS fluid (something like 1230ppm).

Anyway, this stuff is TDS 1000 Calibration Solution. I'll bring it to the meeting and you can use it for free (or frag donation, lol). Just remember to bring your meter with you.

Cool. My meter specifies 800 ppm fluid but I'm sure 1000 would work just fine. Thanks.
