Used as stated on instructions, but had 3 fish die after 2nd dose. Is there something in this product that could have cause this? Looks Chemical burn

I have used many times but didn't kill any fish though I don't have tons of fish. I usually like corals. I would suggest contact Brisghtwell.

I have a small refugium inside my display tank if I add this my live stock will be fine?

"It says it won't". It won't what, be fine, or they mean it is fine for live stock?
