Ph and conductivity solutions for apex?

[LilysDad]

Does anyone use a different ph and conductivity solution for calibration on apex? I’m already using Hanna for dkh and cal and salifert for magnesium on my trident. What solutions would do you recommend to use on ph and conductivity?

Nope, I use the Neptune ones. There may be other compatible ones but the Neptune solutions are relatively cheap.
