46g Oceanic bowfront-magnet?

Hi folks,
I haven't been here in years...you all helped me immensely starting my
25g reef 3 years ago. (Info at: www.wildaboutcats.org/reeftank.htm)
Well, it sprung a bad leak the day after Christmas and in a panic,
I've moved everything into a new 46g bowfront. Love the tank, just
wasn't planning on moving under such circumstances.

I have a Magnavore 2 that I used on the 25g. I would like to use it
on the 46g, but was a bit concerned about the curved front. I did a
search here, but the only discussions I found people using them were
very large tanks in comparison to mine. I'm assuming there is more
curve to mine, but the magnet is also less strong than a Magnavore 4,
so... Is it safe?

Thanks! Dawn
