    What value? You get 4,7,10
    You will need 2, what does your ph monitor calibrate too?
    If using for carx then use bottom too, if for tank then use top scale
    That's how I do it

    Thought I would share what I am doing to calibrate mine. I am still working on it though so my master plan is not perfect.

    Using pool PH up and PH down at R17 bucks each so your in for R34 from builders.

    Mix your own, you must have a PH test kit with already.

    The PH 7 is easy, I've mastered that one...... its the PH10 that's the toughie. Why?, well my test kit only goes up to 9.0 so I'm just playing with the chemistry, so far I've managed to get the RA to give me a PH tank reading of 7.9 against my test kit tank results of 8.2...................

    Like I said, just thought I'd share the idea.

    @Riaanv
    Have you tried the sponsors , Perkies or SAMs ?
    They should keep profilux calibration fluid which I think is 7and 10

    I may know of another place but they are not a sponsor, so no mentioning them here .
    If you don't need it urgently I am sure they will order it for you , otherwise pm me and will give you contact number of "the other place"

    Both Hanna and Milwaukee have agents in Cpt. They definitely carry stock.

    cheapest option go to your local pharmacy and by Borax
    Mix as per directions and use that to calibrate works fine for me
    I have a ph meter and a digital ph pen

    Borax only gives one calibration point, is a bit far off from where we are measuring. Useful though, but best to get 7 & 10

    Agree, the reef angel requires 7 & 10 for calibration. Think the reading will be off if correct values are not used.

    You don't need to use ph10. There are loads of threads about it on the reefangel forums detailing how to do it with ph4 and ph7 fluids.
