You should not need to use these especially if you use a salt with these things in them. The St and Mb trace elements are usually not neccessary and they tend to bond with other things over time. I'd avoid that one after so long.
Other concern:
In 48 hours you did a massive water change. I hope when you wrote "thoroughly cleaned" you did not kill off your good bacteria which lives in the rocks and sand. Monitor the Ammonia levels for the next month if you did.
Calcium does not expire too easily IMO but someone like MDP would be better able to answer that.
