Great Stuff?
 

If I am not mistaken the stuff in the red can is reef safe? I tryed doing a search but the words "great" and "stuff" are pretty common. Can anyone confirm this please?

A quote from another forum.....
"There was a huge thread on RC about this. Some people have had success with this but a member contacted Dow and asked them what effects would a saltwater tank have on it. It is reef safe, yes...but the manufacturer stated that the salt will eventually deteriorate the material."

I used a different product than great stuff. Although I hear you can use it, just make sure it is black in colour. I hear the yellow will break down after while. I'll post a pic of what I used when I get home tonight.

There's a black spray foam that is marketed for ponds (rock work) that works too. Sold in most garden centres and some home depots.

Thanks. Im 99.9% sure that the yellow is safe, I have seen it for false wall build threads, its just difficult to search for.

Thanks. I have looked through your thread, I knew you did the same thing that I want to do, and saw the pond foam you used. Brand name would be good though and place of purchase.

Thanks Kien. That's the link I was thinking of.

Whoa.. déjà vu..

I think it was called aquaseal waterfall foam, bought it in town here for about $16 a can. Again, I'll confirm when I get home.

Sorry for the late reply, but this is what I used.
