not as high as i expected. I did have to calibrate it when i first got it, it was a little off. But dead on now.
i also got a little cheap digital temp gauge
Straight out of Tap= 7.56
Tank=7.87, seems to go up overnight and will be as high as 8.01 when i get up in the morning. But by the time evening rolls around 7.87-7.9.
I'm running a drip, so i hope it stays pretty consistent if not i will adjust drip accordingly.
I thought PH drops from Tap --> tank. Not increases Tap--> tank.
The ORP would be interestiong, especially PRE Uv and then again Post UV.
Just not sure what to look for.
