Your salinity is too low, calcium way too low, and I am suspecting your alkalinty is out of wack as well. pH is fine, but on the high side of fine. What temp are you running at?
I also suggest you test your pH in the morning, then at night to see what the swing is.
How do you make up your change out water? Are you letting it circulate for 24hrs?
CBS are solitary beasts in smaller tanks, you cannot add another shrimp as the CBS will eventually hunt it down and kill it.
You can get an iodine test, but they are inaccurate. If you are going to dose anything, you must test for it. If you do proper water changes, the iodine they will need is in it. You do not have enough critters in there to draw anymore than what is in salt mix. Iodine dosing is for people with a very large number of inverts that will use up iodine quicker, and even then, trace amounts only should be added.
