just change the water
+1 Just keeping changing the water until it becomes stable.
Also when you use chemical treatments be sure to turn your skimmer down, because it will foam up like mad until all the treatment has been removed. You also said your test kits were old or expired, I would strongly advise you to replace them with something dependable. You cant really get anything under control, if your water test are incorrect.
Good Luck.
