Hello all! I am not new to the apex world. I have had the original one on my 40 cube for 5 years. I recently set up at 180 and bought the newer EL version and set it up on that tank. However I am trying to calibrate PH probe and it settles around 450 on both the 7.0 and 10.0 solutions. This is return says my tanks ph is 3.7, which THERE IS NO WAY! HAHA.
Any advice would be great! I have tried the automatic calibration but it times out on the 7.0 solution.
