What you opinion on the icecap 2k gyres?

[alain Bouchard]

my 3ks have been in my tank for about 4 years, and there is no sign of rust at all, and all my corals and sps are doing great.

Are the magnets exposed on the 3k just like the 4K? Do you need me to send a picture for reference ?

by "exposed magnet" do you mean the impeller magnet that looks like this?

IceCap Gyre Impeller Shaft

Replacement shaft for the IceCap 1K/2K & 3K/4K Gyre Flow Pump

If so that's pretty typical of any pump impeller. The magnet is coated and sealed against corrosion.

Or did you mean the magnet mount? I just checked my 2K mount and while it looks like "exposed" magnet it doesn't show any signs of corrosion or rust whatsoever. I'm fairly certain there is some sort of coating on the magnet to prevent that from happening.

A pic of yours might help clarify things further.

No i am not referring to the impeller shaft I’m talking about the actual wet side mounting. When I contacted Coralview they mentioned nothing about a coding on the magnet all they said to me was they do not know of any issues. Here’s three pictures of what I’m talking about first one is just the pump second one you can see the magnet with my finger next to it third when you can clearly see there’s no coating. It’s a ruff piece of metal.

Also from my own experience rust isn't as detrimental as most fear.
GFO is basically rust that people have been using to control phosphate.

Years ago when I did a tank move, I accidentally dropped a rock and broke it in half. What I found inside was a chunk of iron that had been encased in calcareous growth and it was all rusted inside. This rock had been in the tank for years and I didn't have any issues that I can attribute to rust or metal exposure.

So aside from having equipment failure due to rusting I think the risk if any to the tank is minimal.

I’m trying to get this figured out so I can return them and get other pumps without exposed magnets if it’s gunna possibly cause issue in the future

I like expensive corals and I don’t want any issues.

There would not be so many threads on people finding rusted mp40s or probe holders or float sensor brackets causing issues that was corrected by removing said rust then would there be…

Anyone out there been running a 4K for year or more wanna pull this magnet out and check it for us

Do you have 1000-2000 dollar each acros in your tank? If you did like me would you take this chance

That tank WAS SPS dominated. Though I can't really compare values since SPS corals were a lot cheaper back then when I could buy whole colonies for $100-$200

I just took the magnet from my gyre mount out and compared that to a pump impeller from my Eheim and honestly I couldn't really tell the difference as to whether one was coated or not?

At the end of the day though, it's your tank and your corals so I get the hesitation. All I can say is I haven't had any issues at all with mine. The magnets are completely free of corrosion and rust and they've been in my tank for months.

the magnet on my 3k looks exactly the same. no trace of rust at all. And as stated earlier, I believe it has some kind of epoxy coating on it. It does not feel "rough" like an exposed magnet, but smooth like epoxy.
