My pH is well over 9. The only thing I did was add iodide to. Please help.

What test kit are you using? Also you might want to take a sample to your lfs and compare results. I wouldn't worry about 9. Why are you adding iodide?

I'm using a api saltwater master kit. I did take a sample to the LFS and he said my pH was hi. I come home last night and my goby and my chrome fish were both dead.

Does hi ph cause cyano ?

Take your lids off the tank, and point the powerheads at the surface so you get a ripple effect, make sure you skimmer is in top notch condition. All this will help with the gas exchange from the water.
No cyno is a bacteria. Excess nutrients in water column,nitrates, phosphates can cause algae problems. Increased water circultion and siphoning of the algae will help get rid of it. From what you are saying you need to do some water changes and get water parameters back where they should be. Don't add anything untill you get this back in ballance.

OK I added some live rick from another tank. It had a lot of bristel worms in it. I don't know if that messed up my tank or not. I started growing a lot of cyno a month ago. I put some red slime in it and it didn't get rid of it. My yellow damsel is doing fine. I have no idea what's going on.

I also question why you are adding iodide??? And are you testing for iodide? My rule is if I’m not testing for it, I don’t add it!
Now to your pH problem:
The first thing I’d do is to verify that you truly have a pH problem. Go to an LFS or fellow reefer who can give you a pH value. I’ve seen it too many times where people think they have a pH problem and start trying to “fix” the problem only to eventually find out they had a bad pH probe or pH kit.
You did not mention, but is it a reef tank where you are dosing some sort of alkalinity and calcium. Limewater can and will drive pH high, as well as some “two part” alkalinity products. At pH 9, you will definitely be getting precipitation of calcium carbonate…..on everything.
I agree with gas exchange…..you need to get carbon dioxide in that water to drive down the pH.
