OK. Just so I can really visualize this. Are you saying that to reach the bottom of a 24" deep tank, you stand up on something, lean over, reach over, and have the water level get as high as your neck??? I mean, wouldn't the worst case be resting your armpit on the tank frame? To get you armpit under water would sort of require your turning your body and reaching down with the side of your head close to, if not in the tank. Wouldn't you then have to worry about your hair getting wet (doesn't apply if you wear a buzz cut)?
If you're concerned about getting speedstick/mitchum/whatever on your tank frame, how about placing a towel there so your bare armpit doesn't rest on the frame? I would have asked how you keep your clothes dry, but I guess given the concerns, aquascaping and maintenance must be done naked from the waist up (at a minimum, I guess from the waist down in personal choice).:shocked1:
There's also the corollary, if you don't use an antiperspirant, aren't you concerned about your armpit getting sweat into the tank? Then again, depending on what you keep in the tank, aren't you worried about getting stung in your armpit? That can't feel good. What about an aggressive clown going after your armpit? It's not like you can jump backwards when you're halfway in the tank without either pulling down half the rock, falling over and hitting your head, or getting hung up on the tank frame and taking it down with you.
Not to be overly descriptive, but what if your don't shave under your arm? Is it OK if a hair or two gets lost in the water? It's bound to happen eventually. I know I work hard keeping dog hair out, I really don't want to worry about another source of hair getting in there.
Somehow, I think there should be a rule, sort of like the one your mother told you about not putting anything other than your elbow in your ear. I think it's reasonable to say don't put your armpit in your tank (unless you're wearing your wet suit at the time). It's not a swimming pool.
