Oops. Dropped my hose nozzle into water tank

As above. Apart from feeling like klutz I'm not sure how urgently I need to remove this. It's the yellow plastic hozelock standard nozzle and it disappeared down the funnel when j was filling one of my water tanks. I don't know if it'll Bob around but cause no harm or whether it will block sonething.

Any ideas?

Thank you

Buy a new one and see if it floats.
If it does flood tank with hose at bottom creating an eddy. If you are lucky after a while your piece may happen upon the filler pipe.
If it sinks....leave it. You are probably going to drop something else in there anyway.

Thanks. I was just worried in case. there was a chance of it blocking something particularly in the calorifier
