I'm not sure on the skimming question at all. I don't have that problem.
As for the water level indicatior, I usually fill mine past the high level indicator. From what I can tell, if the tank is level, there shouldn't be a problem. I have a 29, but I have not had any problems with it so far with the water level above the max line.
Sorry for not having a bunch of info, but hope it helps.
