Test kits

[DJM28064212]

I hear everyone talk about how good salifert test kits (alk and cal) are so good, but they are hard to come by. I was wondering if there are any other test kitsa out there that might work almost as well?

ZQ has Salifert Mag and Calcium when i went by this week to look for an Alk test. I honestly dont see why its so hard to get them in stock here. Other stores dont seem to have a problem...
