Does vibrant effect solar corals?

I recently started dosing vibrant in my 29 gal. All my soft corals are now shrunk up. Is vibrant doing anything that would cause this? They were are very happy before

I use vibrant weekly, half the recommended dosage once a week. My softies haven't shown any reaction to it. Seems like there's a lot of mixed experience with it though

I think the dissolved algae is getting caught on them maybe? I’m getting a lot of stringy algae slime. Did you have that experience?
