At Mark Klier's Saturday get together a while back, we discussed using magnets to hold corals, powerheads, etc. I measured the magnets that I used to hold a good sized frag rack. The same magnets held a maxi-jet 1200 fine as well. My tank is only a 75 gallon, but the magnets had no problem holding what I needed them to.
The magnets I used are 3/4" diameter and 3/8" thick. I bought them from kjmagnetics.com
Unfortunately, they don't have the epoxy coated ones that I purchased years ago. They do sell smaller epoxy coated magnets, or plastic coated ones in the size I ordered.
Mark, I'll bring some the next time we all get together so you can take a look at them.
