Great Quality Magnets By Patrick on 4/23/2016

These magnets are really great quality. I paired this with the black egg crate (also on sale at BRS) to make a custom frag rack. Simply cut the crate to size, super glue in place, and you're good to go. The magnets are really strong (at least on my tiny 10g) and have no problem holding a 7x5 frag rack.
NOTE: this says it includes two magnets. To clarify, this includes literally two magnets, or ONE usable set. One magnet for the outside of the tank, one for the inside. While these magnets are strong, you may need two sets depending on the application.

These magnets are very small. I have seen similar magnets that were 3" wide. these are only 1 inch wide, about the size of a piece of trident gum overall. I only ordered one set for my frag rack (had suction cups before) and i should of ordered 2. I just ended up leaving the suction cups on and added the magnet for better protection from falling.
They are very strong magnets! i wish they would list the size and recommend at least 2 sets per frag rack or only one set if you want to make a nori or probe holder.

I bought these for a curved tank to hold netting in place. 1/2 glass and they did the job!

Seriously, if your looking for magnets for making your own frag racks, probe holders, whatever, whatever......your search is over. Super strong, very small, perfect. I use CA glue and the black egg crate stuff and get my MacGyver on. We have 9 sets now doing various amazing magnetic things in our 2 reef tanks. Nice work Ocean Wonders.

The little magnets are extremely strong. I bought these to hold my home made frag rack in place. I bought extras to use on other projects. Will most likely buy more at a later time.
