Rusted frag rack magnets - next actions

[aumoenoav]

I have been struggeling a while with zoas not being happy and a bit stressed. Nothing extreme, but bad enough. I went through the equipment and seen the frag racks is rusted / corroded in the magnets.

Did a ICP test and got some high tin. https://www.triton-lab.de/en/showroom/aquarium/auswertung-b/icp-oes/46482/

Any ideas what to do next. Triton Detox? Lots of water changes? Carbon? Just leave it alone and it will go away?

Most of this is overblown. While the magnets should be replaced, they are not likely your issue. Aragonite will bind most metals and render them useless in the water column, and these are no different. If if makes you feel better, you can run some carbon and change some water, but just the normal benefits from doing both are probably going to affect your tank more than removing whatever might have come from those magnets.

I took this out of my tank a while back. There were no issues in the tank.


Edit: most tin issues are from the salt mix. Not all, but most. Did you send in any freshly mixed salt to get a baseline?

Granular ferric oxide and water changes.

Not all magnests are created the same. And water volume is a consideration when considering contaminants. Ie , two magnests in a 50 gal or two in a 100 gal.

I agree, the maganets may not be the issue, but the gfo and wc are the general cure.

GFO is rust, you should not have high phosphates for a time. Just let the iron dissipate, toss the racks, and get something new.

It’s not the iron in a corrosion incedent that causes problems. Its other metals used in the alloy.

I also forgot that a lot of metals can bind to organics and then be skimmed out of the tank. Between the organic binding, aragonite binding, some GFO if you choose to use a bit (be careful not to go too fast) and some water changes, your tank will be aok in no time.
