    Default Strange pH Issue

    What in the world is going on in my tank? I am not dosing anything. I did change out a Vortech with 2 Tunze pumps around that time... I don't think the probe is malfunctioning because everything in the tank looks like garbage.

    I think I turned down my GFO and Carbon reactor around that same time. It is now off... Let's see if this stabilizes everything.

    The only thing that makes sense is a faulty probe. I did do a test with a cheap API pH test and it looks like I am around 7.5-8.

    So corals look bad too?

    Although I don't think stray current should bother corals, I would look into a bad heater possibly a pump. But given how the graph looks it appears it is something being turned on/off.

    Hmmm... It might be my chiller pump. I cycled power on it and the pH started going back down to normal.

    I pulled out a voltmeter, but didn't see any stray voltage. Next time the pH spikes I will test again. This tank has been nothing but a frustration lately.

    That's weird. That would drive me crazy. It's got to be the probe.
