I currently have been using salifert test kits and have been pretty happy with the results I have been getting. However, I purchased a calcium test kit about a year ago or less and recently noticed the readings are skewed. I have been performing the test several times and have been getting different readings each time. The expiration date is 2011 so it couldn't be expired.
