PH probe

Saltwatercoral2 · 07/11/2013, 05:54 PM

I have a neptune apex, and i was standing at my fish tank, and happened to look over at my display screen, and noticed the ph reading was dropping FAST. This a sign I need a new probe? I'm guessing its a year old atleast.

I would suggest check it calibrating fluid first. See if the numbers hold.
