So I accidentally dropped a razor blade in the tank. Fell to the back behind rocks and cannot get it out. I tried a magnet and no luck. What's going to happen to the tank? Should I be concerned?
I've dropped plenty, some I found, some I didnt.
I never noticed any issues that were directly attributed to it. A single razor blade is not going cause an issue.
Get a telescoping mag tool. With my luck I would cut myself while working in the tank in the future on a rusty blade. Get some polyfilter pads and check by using it in a few weeks. I also don't think it will cause a water problem
That said, because you don’t know really what the blades made out of I wanted out of there and I agree that the telescoping magnet tool @diana a mentioned is the way to go.
I would get it out if you know it's there. That said, I must have knocked one in at some point and found it rusted months later. No harm done (to my knowledge).
My personal 2 cents is there is nothing beneficial that it can do.
