Is api ammo lock reef safe?

[BlueBuddha]

hey everyone.
I experienced some die off in my tank and have an ammonia spike. I know the cause and working to fix it. The closest store to me only had API ammo lock. I see that’s it’s saltwater safe but is it reef safe? I have some corals zoas and euphyllia. I want to neutralize it so it doesn’t hurt these guys while I fix it.

Thanks everyone !

I don’t know but my guess is that it would be better to use it as ammonia would be far worse. You could check API’s site to be sure.
