I will take it if still available.

Also for the acid solution you can find on R2R other acids you can use vs the GHL acid. I used hydrochloric acid I got on amazon. I forget the mole level you need to get. The link on my Amazon account no longer works. I think it was a 0.1m. Like I said look on R2R. It's a lot cheaper to get the acid yourself.

Thanks so much, do you feel the probe is still usable? I will definitely look it up.

It was working just fine when I stopped using the KHD. I switched from SW to FW planted, so the KHD wasn't needed anymore. I would try to calibrate it. I have it stored in the pH storage solution. I would set it to 3 or 4 during the calibration process. You will also find the KHD setup steps on the GHL manual/download website. The process is pretty easy. The tubing for the acid is a different type of tubing. I left that tubing along with short pieces of the other tubing in place. The nuts that tighten down on the tubing have small collars inside them. I didn't want the collars to get lost.
