I've been planning to do this for a while now. Finally getting around to it.
Not bad for a first try.
Materials:
Eggcrate - Free (already had a sheet)
Pond Foam - $7-8 at Home Depot or Lowes (note: Lowes employees can be ignorant and send you in the wrong direction)
Rock Rubble - Free (already had some)
Zip ties - $.80 (maybe!)
Big Magfloat - Free (thanks Ray!)
Sand - Free (thanks Dennis!)
Steps:
1. I cut the eggcrate to give me a bit of "skeleton"
2. Zip tie eggcrate around the magnet
3. I placed the magnet on a piece of 1/2" plywood and used the other half of the magnet on the other side. This helped hold it down to keep the foam from lifting the magnet up off the plywood. I also laid wax paper down to keep it from sticking too much.
4. Spray foam - be gentle. It doesn't seem to fill much, but it does expand quite a bit as it sets up. I made sure to push some of the foam through the eggcrate structures as well. You can repeat this process if it doesn't fill in the first time.
5. Sprinkle sand over the foam JUST after spraying. It forms a "skin" pretty quickly, so be quick about it.
6. Test it out after 24-48 hours! (I'm hoping mine works, we'll see tomorrow!)
Pics (or it didn't happen, right?):
I'm gonna let it cure out a bit more and then I'll test it out in some water tomorrow night to see how buoyant it is. It may need some more rock to hold it down. Just have to see!

hate to say it man but I have built a few arches out of the stuff it is totally reef safe no worries there but I made a couple little arches about that size and I had to put a 10lb rock on it to keep it down lol.... So basically what I'm saying is I don't think a mag float is gonna hold that thing man you prolly need to start slicing and dicing it to where there is very little foam...:sad: sorry man.... Might want to try it before you get any more involved in it....
