Anyone know what magnets can be used for 3/4 glass. Looking to make some frag racks, but not sure of the strength of the magnet needed to hols on 3/4" tank.
Take a look at www.kjmagnetics.com They have a huge selection to choose from. I use the 3/4 x 3/8 with 10ish pounds of pull for mine but it’s a standard 120. They have them plastic coated and work very well.
