Sucks to hear this Brian. Ive Read a lot of stories about these Eshopps racks doing this. I have one myself and considering the problems Im haveing i think when I get home Im gonna check it out as well. One this i would add to your testing though is Copper. The Rare Earth magnets are a combo of Nickel and Copper. With excessive corrosion it may be possible that some was released into the system. Just a though. When your ready let me know, I can help you out with some nice Monti's to get you back on your feet.
Also quick update, we spent about 2 hours cleaning out the frag tank last night, it needed it. We have been having problems with our ca reactor which lead to swinging alk which leads to problems. We have stabalized things and plan on having a whole lot of fun at MACNA. I will update when we come back.
Ugh! Hope things start getting better Brian.Well, to pour salt on an open wound, I came home the other day and found my bristletooth tang in the power head.
Hair algae is dying off and cleanup continues. Still pulling dead snails out of the tank and doing weekly 25G water changes.

MACNA has really jump started my desire to fix my current tank situation. I've decided that when I get home from FL, I'm going to completely drain the tank and do a 100% water change. I'll clean the tank and sump and rinse and soak all my rock work.
I'll use this as a chance to finally:
1) replace the vinyl return hoses with PVC
2) replace the flex drain hoses with PVC
3) add a manifold to the tank
4) add a refugium to the sump
5) install a cabinet ventilation fan
The fish will spend some time in my 40B, so my first task when I get home will be, to get the 40 up and running.

Sounds like a good plan.
From Wikipedia:
So the blue corrosion on the magnet leads me to believe they have traces of copper in them and might explain why my snails and inverts are dead.

I mentioned about the copper a few posts back. It amazes me that for a metal us reefers try so hard to keep out we sure are quick to add these magnets knowing they corrode specifically this eshopps rack that has reputation for doing so. Hopefully you can get the traces out of the system. But this could explain the coral losses as well.
I spent about 5 or 6 hours working on the tanks today. I have the 40B setup and about 3/4 of the way full. I should have it full by tomorrow, had to make some more SW.
I spent most of the time scrubbing hair algae off the rocks in the 120, and removed a few dead corals I missed from the last cleanup. Also gathered all the snail shells and blasted all the rocks with a powerhead. I went through 4 filter socks through the whole process. I'm just tossing them, not even going to bother to try and clean them, the are that nasty.
I did find a few corals that are surviving and things seem to be getting better now that the frag racks are gone. I've been doing weekly 30G water changes and i'm sure that is helping. My hammer and colt are fully open, and my green giant zoas are finally starting to open up again. As I mentioned, I have a small branch of ORA green birdsnest and a frag of green digi that are alive and had some polyp extension. I just hope they survive the transfer to the 40B tomorrow.
I also installed the wireless RF modules in my MP-10's and linked two pairs of pumps. The two sides are linked and set to anti-sync and the two pumps on the back are paired and synced.

It's the coating of the magnet that has the copper, but i'm sure the neodymium is not good to have in the system either. The racks should have had the magnets epoxied in place and then covered with the acrylic caps. The magnets were just crumbling when I took them out of the rack to examine them.

Mine are gone, no way will I put them in any tank. I'm surspised that something specifically designed for reef systems would have any copper in there manufacturing. Thanks Brian, if its any consolation you probably saved a bunch of tanks with your post. I had those racks and eventually they would have failed and crashed my tank.
I pulled mine yesterday. Its clear that the outer surfaces of the magnets were oxidized on mine, though they were fully intact. As far as being designed for reef systems these racks are not the only things that contain these magnets, think of the magnets that hold powerheads and pretty much every other frag rack out there. The eshopps racks just have a track record for failure though, and we all run to buy them.
Still the same magnets. I recently just tossed one that had a crack in it too. though they do hold up quite well
Things are looking better, still have some patches of hair algae. With everything in the 40B I'll be able to do much larger water changes to keep nutrients low and kill off what little bit is left.
