Imagine my excitement...

I was walking down the isles of Walgreens and lo and behold...they sell TDS meters..don't know if they are worth a shit, but thought it was cool.

what a tease... You give us that info, and give no price, or brand.. hehehe Now I will have trouble sleepiong tonight.

Go to Sears they have aero units mainly the Aerogarden...lol

It was like $14.00..can't remember the brand..said it was good up to 9999 ppm. Nice back up if your old faithful shits the bed.
