Do you have any pictures of your current water monitor enclosure swampdonkey? A 4x4x2 would have even less space than what Superman is in now. I don't have a filtered pond for him but he seems to have just as deep of dirt as yours and he gets daily baths. His humidity stays perfect with just his large water bowl and his basking temps are 130-135.
As far as the rude thing, there are alot more productive ways of being informative.
