Magnet Size

[Shawn.B]

I'm looking to build some high quality frag racks (Think Zen Reef) just wondering if anyone has magnet Size recommendations or knows what size Zen Reef is using? I'm looking at 25mm x 3mm rounds

Cheapo ones can be had at the big box hardware stores.
I'd look into neodymium magnets

I just measured the magnets Zen Reef used for the dual heater holder and they are roughly 8mm x 28mm. Only two magnets, one on the inside of the sump and one for the outside.
