Could a compromised magnet be poisoning my sps?

I've been struggling with base up STN for a while now. It's essentially rotating around the tank.

I tried fragging the colonies but it usually just starts up again shortly thereafter.

Tank is over a year old and is very stable.

Noticed this cheap lettuce magnet today had completely split apart and was totally rusted out.

Thoughts?

Yes. I alway check mine as I work on my tank. If they even look funny I throw them a way.

It is not likely. While long term exposure to heavy metals is no good, aragonite will bind a lot of them and skimmer will get a lot too.

Some Polyfilter will get it out and change colors if you have a problem.

Although that nasty thing needs to get out of there, I would look elsewhere for your problems. If you have some photos or some more info, we might be able to help... parameters, colonies or frags, etc.
 
Tank is over a year old. Very stable. Routine water changes. Tons of flow with two MP10's and a Gyre.

This is the only explanation that I've come up with....
 
Interesting!
We run GFO in our tanks all the time, which is essentially rust. So why a rusty magnet be a problem. Not sure.
Can anybody shed some light.

It isn't the magnet unless it is rare earth. There is very unlikely to be a rare earth magnet in a $8 veggie clip. There can be some other impurities, I guess, but it is VERY unlikely that they were what did the damage.

Chemicals on hands, magnets, toxins in the air from cleaning lady... all are tank crash red herrings.
 
Post a few quick photos and some water parameters and see if anybody can help.

If you have colonies, then they are going to start to die from the bottom up with three kessil lights - they cannot cover well enough to keep SPS colonies healthy after a while. If the N and P are higher, then this can be an issue too. If you still have frags, then it is VERY easy to look for pests - nobody who ever has had pests originally thought that they did, so please look well.

Agreed With sps tanks you should be testing once a week. Are you. Typically with sps once they start dying from the bottom up even if you frag them , they still might die.
Pictures would help

When asking for help it's best to post as much info and pictures because without all this info we are just guessing. Also it helps to give test dates and results. Give a month of results would be best

In my research I'm finding that these cheap magnets are often coated in nickel and copper is used as part of the adhesion process.

So as the magnet is compromised due to the cheapo coating... It rusts and these materials get in the tank. That's what I've read anyway. So it's not simply rust at this point. There are toxic metals associated with the production of these magnets.

I am not sure if it was the magnet either. Sps are very hard any little change can wipe out a tank In days. If it was the rust. Why wouldn't it have happened why before the magnet totally looked like crap

The magnet appears to be have been corroding for months. I just finally noticed it when the cover plumped from the rust build up.

My point. It was there for months. And then after 60 days it caused your stuff to die. Also not to sound mean but if you didn't notice a very rusty magnet maybe your maintenance schedule is something to be deserted
