I wonder if one of my test kits have gone bad and it's giving me bad readings. Can it be caused by calcium or mag actually being too low? My alk kit is faily new and i compared the alk to my old kit and it's only .3dkh difference. The mag is a brand new kit but the calcium is needing replacement soon but still within expiry.

well i personally won't put that theory to rest.
i tested water regularly but recently switched all my products over to aquaforest product (probiotic salt and their balling method) and wanted to test a little more rigorously so i bought new test kits. against my old salifert test and using the same water sample i'm getting readings of 430 calcium 8.6 kH from my old kits to 500 calcium and 11.8 kH from the new. my corals and livestock look improved at the moment so i'm not going to adjust but it's tough to trust such variance especially when the colors don't appear equal.
