Most magnet mounts are encased in plastic or acrylic.
Hmm, I think some powerheads have exposed magnets, don't they?

Well, I know of two reefers using these magnets in their tanks, both for putting frags on and sticking it on the side of the tank.

The magnetic frag plugs you can buy are sealed magnets which I use on my tank. Clearly nothing stopping someone from using cheap magnets in their tank however.

After doing a bit of reading the main concern is rust which apparently is inert although it will discolor the water in even small quantities. The second is the quality and construction of the magnet. Some magnets use alternate metals to help with the brittle aspects of a magnet. Some of these metals apparently can include copper. What I haven't been able to figure out is what Barium or Strontium carbonate does in saltwater which is the bonding material for a ceramic magnet. I am guessing Barium isn't a big deal, but Strontium carbonate may be.

Interesting findings.

By the way, I meant that I know two people that are using the ones from Lowes.

I assumed that was your meaning earlier. I was just noting the company that sells them uses a sealed version. Seems like some kind of small film canister item they stick the magnet in.

One thing to note is, that I forgot to mention, that the people I know painted the magnets with krylon fusion paint (black) and let it dry. This paint is used by several people (as you probably know) in and out of tanks and is, as far as I know, "reef safe." Maybe that is acting as a 'sealer.' Whattya think?

I can't find anything against krylon in the tank other than the usual reseverations of putting a fairly pre-dried toxic substance in a tank. I have no idea of Krylons chemical composition after it dries nor its perpensity to dissolve in saltwater. I do know you are correct that some people run it in their tank with reported success. Assuming it bonds well to a magnet, it should prevent leeching/rusting of the magnet metals.

I am not sold on paint in a tank though. Acetone, Propane, Toulene and a host of other chemicals are found inside Krylon. I go by the simple rule of thumb that I don't put anything in my tank unless I have a really good idea of what it is and how it is going to react or I personally would actually drink out of a container loaded with it.

Let's try to keep this thread on topic... "useful items and where to get them"
We can take a discussion to a seperate thread if needed.
Thanks!

For those who prefer their bottoms bare...

Much cheaper than a huge sheet of Starboard, and available in black.

If you want to make your own two part additive I found Prestone Driveway Heat at the Publix on Towne Lake Pkwy. in the spring and a huge (15 lb. I think) bag of baking soda at BJ's in Woodstock. You can also use the baking soda in your pool to raise the alk. I think it was $3 for the bag.

Power cord extensions. These are suprising handy and beat using a surge protector for one or two power connections.

What I did was just bought as many timers as I needed and then if more than one thing needed to be on that timer I plugged a powerstrip into it.
