Where to buy foam?

[reefguy40gal]

I need to buy a small piece of foam to put in my reactor as the other foam is damaged.

Can you guys tell me how to describe the foam? Is there a name for it?

Where to find it, home depot? Michael's Craft store doesn't carry it....

I normally buy all that type of stuff from the LFS...they have all different sizes and densities that can be cut to fit. I am surprised a place like Michael's doesn't carry it though since foam is used in crafts.

Most lfs will have somesort of foam blocks used in hang on back filters.
