Might have lost my exacto blade in tank..(?) What if..

I think I've done the same, never found it. I figure it can't be any worse than the rusty hose clamps in there, so I didn't worry about it.

I wasnt sure if it would crash my tank after it rusted.. ill do my best to look for it still!

Thanks!!

Better to remove it if you can, but not a show stopper if you can't.

Technically, you should be able to find it with a relatively powerful magnet in the water. But I think you should turn off the powerheads so that there is no flow since the water flow MIGHT cause motor effect with the magnet. Just move the magnet slowly around the water and you should be able to attract the blade.
