For starters, clownfish do not need anemone. Both are just fine without the other.
Can you show us what your light is? That really doesn't mean very much to me.
What are the current parameters? Why are you dosing, there isn't enough in that system to have enough of a draw on parameters to need dosing of calcium, let alone iodine. It takes an extreme amount of SPS
corals to draw to the point of needing to dose over what will be easily managed via water changes in your system.
So, make sure you are using ro
water. Do a couple large water changes no more than 50%, too much of a good thing can be a shocking stress as well. Check the parameters and see how its going. I want to point towards the lighting, I see an anemone that requires intense lighting stressed out and another that doesn't need as strong lighting doing just fine. Most likely related.
