Rust of AA Green Killing Machine

[BurgerFish]

Hello,

I have AA Green Killing Machine 9W and 24W. Both rust inside the pump in 1-2 years (or sooner).

Is that normal or dangerous?

I attach the photo of rust of AA GKM 24W:


Thanks for your help.

1. Are you talking about the brown area on the bottom?
2. Its a little unclear what part of the pump that is - but Is it where the magnet for the impeller goes?
3. What does the rest of the pump look like?

If it is 'rust' - I would not use it in my tank - for a number of reasons.

2. Yes, magnet is there.

The impeller is a little rusty. I attached a better photos:

That is not 'normal'. I would ask the company perhaps for a replacement of that part?

Yes the GKM will rust in saltwater eventually , I don’t think it is intended for saltwater use but it is nice in a pinch or when fighting dinos

The official answer from aa-aquarium.com:

"I have checked with our team. Since it’s submersible and operated inside water, a little rust after 2 years is normal.
Is the pump still working? You can just put it in after maintenance, is ok to use.


Best Regards,

I've used both of the GKM setups. It's normal after sometime. If you worried, just replace the pump, they sell it as a maintenance item.
