DIY Seio 1500 magnet mounts

[mfinn]

After using magnets to hold my maxi-jet powerheads in place, I started looking at the suction cups on my seio 1500 powerheads that were losing their ability to hold the powerhead in place.
I found some neodymium magnets on line that looked pretty good. They are 3/4"x3/8" disks that were about a $1 each. And couple bucks worth of acrylic and I have a magnet mount for my seio's for about $10.
This magnet mount is holding the seio in place through 1/2" glass and is very difficult to pull off.
The one thing I didn't like was to have to use alot of silicone to glue the seio suction cup bracket to the acrylic and to seal in the magnets.
Smearing silicone in a neat and orderly fashion is not my strong suit.lol.

You da man!!!!(LOL) Looks great man! I see a lot of people DIY'ing this same thing now! Almost looks like my Tunze magnets! Good job

Thanks, but I think most people would just keep buying more suction cups.
Atleast untill the pump falls down and blasts a favorite coral.

I guess this would work for just about any large powerhead.

Awesome idea...I hate having to mess around in the tank adjusting the darn things, and I have lost coral when a pump fell.

what site did you get the magnets from? Also, are they sealed from the saltwater?

I got these from www.magnet4sale.com
I used silicone to seal the only two edges that would be exposed to saltwater on the inside piece.

I made some changes to my little project. One thing I wasn't happy with was using silicone to attach the seio suction cup bracket to the acrylic, so I drilled the acrylic and used a nylon machine screw and wing nut. I also totally incased the magnets in acrylic. I also made both pieces smaller, but used a little stronger magnets.
Here are some new pictures.
