i bought both my meters off amazon my PPM is a hanna and it was like 20-30 bucks, the PH/Temps meter was like 80bucks on sale from 120.
in regards to how often i test my PH is like every 4-5 days. lately my BS in the DWC has been drinking 1 gallon of water a week so i just add 1 gallon nute/PH water and some aqua sheild once a week. DWC can be very simple once you get your reoutine down!
