Is this sand okay for a reef tank?

Yes that sand is okay to use

It should be safe yes. It is very fine sand though and will blow around a good amount in moderate or above flow. Reef sand is no more costly however and in my opinion a better choice, but again if this is what you want it should not hurt anything.

I would look for their aragonite sand that says “special grade.” Many people agree that the grains are the right ‘in between’... not to large, not too small.

+1 special grade aragonite.

It is safe but it is a fine grade silica sand. You are better off with something calcium based to help keep stable ph. I wouldn’t use it.

It is safe but it is a fine grade silica sand.

For that reason, it might also fuel diatom growth.

I wouldn't use it due to the silica. I thought of using it when setting up my 150gal, but when I went to rinse it out I noticed a bunch of sparkling grains, like fools gold in it.
I decided on oolitic aragonite instead.

I think the Super Naturals line is made for FW tanks. Others saying aragonite for SW are correct — they make both live and dry aragonite sands meant for SW tanks.
