Testing equipment passed expiration...

[Tourpicks1]

I just realized that my testing equipment has expired for over a year.
I use the red sea 5 in 1 testing kit and red sea calcium and magnesium testing kits.
my questions are 1- is this a decent testing kit ?
2- the readings im getting which show good parameters are they false ?

1 more note i recently tested alkalinity and it was low/normal and after adding kent alk buffer it went to high so it did change. if anyone has any info on this please help.

i already ordered 6 in1 new testing kits.

im not sure, you cant trust test kits over their expiration date, although red sea is pretty good. my advice buy new test kits

i did buy new kits last night!- thanks, i thought red sea test kits were imho easy to use and accurate- however they did expire a year ago. i will double check when i get the new kits.
