this morning i was working on my MH light. i unscrew on one of the side section. when i was done, i screwed the section back and .... i dropped one of the screw into the tank
i have searched for it but couldn't find it. i suspect it dropped into the hole of my rock work
now, if i leave the screw inside the tank, it will corrode and rust. how? should i just leave it or remove all my rock and search for it? it is going to be a big worked out man if i remove everything
it is ok to leave the screw inside the tank?
