  • no problem By Bruce on 7/12/2015

    Glued these to some egg crate and made my own frag rack for 1/2" glass
  • Perfect for net tops By Jeff on 2/6/2015

    I bought these for a curved tank to hold netting in place. 1/2 glass and they did the job!
  • Beez Kneez....Buy these. By Hawk Mo on 4/18/2014

    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.
  • Very Strong By Robert on 1/27/2014

    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.
  • Great Magnets, Very Strong By Nootch on 11/20/2013

    Very strong, look great.
  • strong and versatile By Gene on 9/14/2013

    I've bought several sets of these for various projects. Very pleased. They are surprisingly strong for their size.
  • Very Strong By Jason on 7/9/2013

    Works great for my DIY frag rack on my 40B without issues.
  • Strong By Terry on 3/21/2013

    I didn't really know how strong these would be so I thought that for the price that I would give them a try. WOW, I am glade I got them.
  • very strong but not strong enough By Puffer on 5/9/2012

    Magnets are very strong but not nearly enough on larger tanks (like my 180). The glass is just too thick and addition of any extra weight like an urchin or jumbo turbo snail tips my self-made frag shelves over, dropping all frags in the process. Again, these magnets are strong (and sealed) but will only be sufficient for very small project or thin glass.
  • Very Strong By SG on 5/4/2012

    I bought these to build a frag rack and was a little skeptical, but this magnets are killer. They are strong! No issues at all.
  • Very strong By Michael on 10/14/2011

    These tiny magnets are very strong. I decided to make a DIY nori feeder like the video on this site shows how to make. It really makes feeding easier. I recommend it and these magnets.
  • Very Good By Lx on 9/7/2011

    Excellent magnets for DIY frag racks. I prefer to use 3 packs with a mag in the centre for extra stability.
    This is one strong little bugger so watch your fingers
