Seachem prime coral safe?

[Wolf89]

Urgent: Will Seachem prime harm corals (elegance, duncan, zoas)??

 

[Spare time]

No it is perfectly reef safe. The only concern is if you dose extreme amounts (which can lower oxygen levels) but that is hard to do.

Most people who use tap use that to declorinate the water but I use it to make ammonia non toxic for 48 hours if something died.

I use it sometimes in my reef tank and never noticed any negative effects.
