Magnets for our HOG scrubbers, or your own scrubber. These are N52 high power neodymium magnets, and come either plain, or pre-sealed in black epoxy. 

The plain magnets can be used on any scrubber, and are grey in color. They will need to be sealed with your own epoxy, resin, or reef-safe silicone, onto your scrubber tray. This is the way we built them for several years, and still do for our smaller HOG.5, HOG1 and HOG1x

The pre-sealed magnets are already sealed in black epoxy, and fit exactly our larger HOG1.3, HOG2, HOG2x and HOG3.. They do not fit our smaller HOG.5, HOG1 and HOG1x, although you could "make it fit" if you wanted to. We currently use these pre-sealed magnets for our HOG1.3, HOG2, HOG2x, and HOG3, however the HOG3x and HOG3xx still use the plain magnet-in-silicone technique, but with added protectors on the wet side.

There are two plain lengths available: 20 mm and 50mm long. They are 5mm thick, and 6mm wide. There is only one pre-sealed length: 50mm, although the length of the epoxy itself is about 70mm. You can use them the way you like, although we use them this way: 

HOG.5 has two plain magnets 20mm long on the inside, and the same outside. This is for thin glass such as 1/8" (3mm) tanks.

HOG1 has two plain magnets 20mm long and two 50mm long on the inside, and the same outside.

HOG1x has four plain magnets 50mm long on the inside, and the same outside.

HOG1.3, HOG2, HOG2x and HOG3 have six pre-sealed magnets 50mm on the inside, and the same outside.

HOG3x and HOG3xx have six plain magnets 50mm long with magnet protectors on the inside, and six of the same magnets outside but without magnet protectors.

Magnet protectors are generally only needed on the inside (wet) part, and usually only on the larger size trays. The protectors fit perfectly over our 50mm long magnets, and fit right into the large trays. The protectors can also be used with smaller 20mm long magnets, or with smaller trays, but the fit is not exact. Protectors are not needed on pre-sealed magnets because the epoxy does the sealing.

Here is a video and picture of a protector being glued onto a magnet:
