This glue reef safe?

I picked this up at harbor freight. $1.99 for 3 tubes 3 grams each. Says it contains Ethyl Cyanoacrylate, Poly methyl methacrylate and hydroquinone.

I know there were other threads like this but I have not seen anyone use this glue.

I would say yes. The kind I have used for over 5 years lists the same two ingredients.
