Hi, not a complete noob but I'm having ph problem
I have a homemade rdwc with 85l but with a 45l pot, the ph of the butt is 5.8 but the ph of the pot is 4.4... why does this happen when the water is the same and recirculating
Also the ph is 5.8 while the pump is running but if I turn the pump off and test it reads approx 2.0 under what it does while the pumps running...
Which should I go by and why is this happening???
Also ph pen was calibrated about 2 weeks ago
Thanks in advance
If needed pictures can be added but not really needed for the questions
