There are a few things that I have questions about pertaining to my water.
The Ph from my RO is 7.7 and tds is reading 190.
My tap water is liquid rock. Ro filter is less than 2 months old and is flushed a few times a week. I have a Milwaukee PH controller on my planted tank and it always about 7.2 when I stick probe in RO water. I bought a Hanna instruments combo meter today and was shocked at how off my Ph controller was and how high the Ph actually was in most of my tanks. So much so that I went ahead and calibrated both instruments shortly after to make sure there wasn't a false reading or calibration error. both were fine and calibrated to 7.0. i have recently been aging 50 gallons of RO in peat and the reading from it was in the 4 when I measured it today.
couple of questions:
-Is this the way I should be dropping the PH while keeping the TDS down to? -Should my TDS and or PH be lower out of my RO?
Thanks, -Bradley
