Myster Coolant Leak

[Pomorza]

I've seen this asked on another site, (or maybe this one) but cannot locate it for the life of me. About three weeks ago I changed my upper and lower hoses on the radiator, did a flush and added new fluid to the radiator and then filled the reservoir up. Checked it a couple days later and the reservoir was low.

Two days later found that one of the hose clamps was leaking. Fixed that and thought the problem to be gone. Today I find that the reservoir is empty. The radiator is full of fluid. I haven't had any smoking and the oil looks greatmstill nice and brownish tan and smells like oil. The oil cap and the cam lobe that can be seen inside is also in great shape.

What's going in? Is there STILL air in my system three weeks later? I don't drive the car much but I would think by now it would have of emptied. I don't see any leaks around the car or at the hoses. Any idea?
