Why are Strontium test kits double the price?

I can’t answer the specific question, but I can bump the thread to see if we can get you some help

Maybe people dont test it as much so they dont produce as many test kits so less something is produced = more expensive.
More mass produced = cheaper

This is just speculation but maybe the chemicals involved are more expensive?

With salifert, it includes both a calcium and strontium test. Perhaps thats why.
