Re: Silver Puppy Question...PPM

I have a TDS-3 meter. I purchased it with the Silver Puppy. Would you recommend I purchase a Hanna meter? I believe my meter cost $45. Also I let it run until the light went out. Correct? It took 11.5 hours for 1 quart.

Thank you so much for your help! I will add some CS when making my next batch. Tweet
