I do not recommend adding ChemiClean.
Yes start adding the Turbo Calcium. You can use the BRS calculator to calculate how much to add.

By adding calcium, that will help bring down your alk.
By adding the calcium gluconate, you were effectively carbon dosing your tank with sugar. Once that food supply goes away, the excess bacteria will die back to normal levels so make sure your skimmer and filtration is working properly.
How much of a change this is going to be for your corals depends on how much calcium gluconate you were dosing and for how long.
After you add the turbo calcium, check the calcium and alk levels again in 24 hours.
You could do a water change, but that would be introducing even more chemistry changes which could irritate your corals further.
Stopping the calcium gluconate and adding the calcium chloride are the 2 most important things to do right now. Don't raise the calcium more than 50 ppm per day.

Good luck!
