just got three nanostreams 6025 from marine depot. one magnet set has protective resin coating over the top. Two others have no coating, wet side and dry side are bare metal. Dry side magnets on the two with bare metal are also larger than wet side magnets. Should there be a coating on wet side magnets?
 
I would think so. Saltwater will eat any metals up pretty quick. I want to magnet rock to my over flow but not sure how to coat the magnets.

I think this is a factory goof, but not sure. Anyone else buy any nanostreams from Marine Depot lately?
 
I know they switched to newer magnets to keep the costs down low. email the pics to roger if need be he will remedy the problem if it is a defect

I have read about using epoxy to coat them. Just a suggestion.

On the note of the Nanostreams not being coated. I got a Nanostream as well, but the magnet on mine is different. It is one solid piece, but it is definitely coated.

Sorry. How do magnets work? Can't help myself. :p

Here's your answer why they don't need to be coated.

i think the word tunze triggers something that changes the link up but just copy and paste it i guess

I thought about marine epoxy but not sure if it would be completely water tight. Some kind of food grade plastics melted down to dip them in was what I was thinking. But not sure how melting the plastic would change the chemical composition

If they start to rust tunze will have to replace them under the warranty

I am no magnet expert but i do have magnetic personality (ba da boom )

I think these are the same type of magnets they use on pump impellers and I haven't seen my impellers rust or degrade over time and they aren't coated either

That's what the write up said. They are no different than an impeller. Wont rust. Too bad they are much weaker

You could probably try the plastic dip that they sell to dip your tool handles in.

personally I wouldn't try to dip or epoxy them. If they are the same type of magnet material that impellers use than they shouldn't rust and I doubt they are as strong so putting another layer between them in addition to your glass would just weaken them further.

This stuff will just peel off after a little time requiring you to constantly re-dip them.

Tunze stopped using neodymium. The ferrite magnets they now use are now very strong. I want so etching I can use to stick rocks to the over flow. So I'll have to use neodymium and that rusts

Thanks kuyatwo and saltnewbie, link explains it all. Just needed some "nerds" to find the info for me! My searches came up empty. Sometimes I wish I was a nerd or geek!

by the way they are much weaker magnets but hold, just be careful when moving/adjusting to final location, mine fell off twice while adjusting. Almost have to use two hands when changing/rotating wetside, roating wet side will cause dry side to hit the floor.
