Yeah, my arms and tank heigth were a learning curve.
Only way I can move stuff around is after a shower or before I put on deoderant, for obovious reasons. I've actually gotten my whole shoulder into the tank, almost up to my ear. I coun't count how many time's I've almost fallen off the chair. Try balancing a clam in one hand, one foot on the chair, one foot in the air and the other hand trying to to hold on while bent backwards trying to look thru the front of the tank to get a visual on where to put the ^%$$ clam....LOL
