YepThanks guys.
I thought so, but... had to ask...lol
Startling drop though... from 6.7 to 5.9? Wow...
Your pens fucked. Get some 4.0/7.0 solution and calibrate it. There's usually a small turning dial for a flat head screwdriver you can adjust until it reads what the solution is rated for.Thanks guys.

I think he was referring to the drop in PH when you are swishing it around as opposed to still water. If not I am mistaken.Your pens fucked. Get some 4.0/7.0 solution and calibrate it.

I dunno... it better not be. I paid the large for one of these a few months ago..Your pens fucked. Get some 4.0/7.0 solution and calibrate it. There's usually a small turning dial for a flat head screwdriver you can adjust until it reads what the solution is rated for.
No they dont.I have two of those combo meters. I never noticed that moving the PH pen around messes with the readings. (The TDS meter is a different story, try putting it next to an airstone) Leads me to think you got something wonky going on.
Do you have strips you can use to double check? I got some narrow-range ph strips from amazon just to double check in case I felt something was off.
Strips dont lie.
That's the right tool.I dunno... it better not be. I paid the large for one of these a few months ago..

And i calibrate it almost weekly... because i have trust issues...lol
But i will say i didnt have this happen last round.
I would just keep it in the res, but my mixing res is in another room. So... it moves around a lot.That's the right tool.
No need to calibrate it so much. Monthly is fine.
Do not store the pH tip in distilled or tap water.
I just kept mine in the res and it was fine and accurate for months at a time.
