[christyahumada]

they look like KJ's but I can't be sure, that didnt say if was from kj site.


I have these same magnets in place for year ten honestly I think we just hit a dec submerged. great magnets, great great reefing magnets. not one crack at all.

I’m looking into the possibility of placing rock onto the glass.

So what’s the verdict on your head ceramic magnets, has anyone tested there resistance in a saltwater aquarium?

I make and sale these and have had them in my system for years with no problems. I coat the one that go inside and as you can see 1/2 inch is not a problem with just about anything on them.

What are these dipped in?

I believe that if most impellers have ceramic ferrite magnets, then they should be relatively reef safe. I have some mini float switches that I would like to use in some dosing containers (Ca, KH, Mg, Vinegar), but discovered that the float has a magnet ring exposed. Do you think it would be safe? First of all, they are not going to be in salt water. Second, they will not be in constant friction (unlike impellers). Would it be safe?

I have been buying K and J magnets plastic-dipped magnets for 12 years now, I have some underwater the whole time, these are the right ones to get.
