Ok got the piping for the sump(hope it's the right size), and got some foam, and for FREE I do have a question tho. This particular store said it's difficult to find that pink foam, and said they carry the blue version of that "same" foam. Now I'm not entirely convinced that it is the same thing, however took the piece because it was free. I will have to cut around there was glue, but it's a great piece otherwise.

Do you guys know if this would be safe to put in the sump vs the pink foam?
