Hi guys,

This may have been discussed but i did not manage to find any related threads.
I would like to know if you got any home-made solution that you can use to calibrate TDS meter?
Or are there any such solutions in the market?

I do know that using the 1g salt with 500ml water method works. But i am not sure how accurate it is.
I am seriously keeping some CRS now. Used to keep normal shrimps and does not bother about TDS.

I would like to know more about TDS and its calibration.
Hope you guys can share your knowledge! =)
