Anyone have wonky Salifert Ca test kit?

[marie]

I've long since come to the conclusion there is no such thing as an accurate test kit under $100.
The only thing I test for now is alk and even then I don't take down any actual numbers, just the position on the syringe, if there is more liquid left in the syringe it means I need to turn the reactor up, less liquid and the reactor gets turned down.
I use IO salt which is consistantly low in cal and MG so I add them to my make up water and assume all numbers stay even in relation to each other

Where abouts are you in Victoria. I can bring mine over to double check if you want, it'll be an older lot #

Instant Ocean salt (not reef crystals) mixed at 1.026 s.g. generally tests out at 360-380 ppm CA.

Mixed up 100l yesterday, Ca 370ppm (Mg 1100).

Out of curiosity what results did you get for alkalinity?

didn't test this last mix, but from one time before recorded 10.9 dKH (believe would have been a different pail of IO though)

You guys can have my thread, I'm done with it now

Thanks, but I just finished off an older kit that gave me real numbers, this new kit is going back to the store !
Using the same batch of salt, this kit is way off the level the last kit gave me.
