Recycling is no source, and you don't get 100% of it back anyway. So even with recycling there will be less, and less water overall. Mars have polar capes, but there is not much light there, so producing energy from Solar Panels, to get water, will not be very effective. I thought about shooting ice blocks from there, using Magnetic Accelerators to suitable Colony location, but now I think best location for Colony will be inside glacier, as that would be easiest way to protect from Cosmic Radiation. Apart from polar capes there is no source of water nearby. Maybe we can produce it from Hydrogen, and Oxygen, but I doubt, there is easy source of oxygen either. So either transporting it from Earth, or one of Water Moons (Europa, or Enceladus). In terms of needed fuel, those moons are best solution, as long, as time would not be issue.

with recycling you cannot get back more than 95%, so there must be some additional source - but I think it´s proven there is some water ice on Mars, plus maybe it can be mined and send there from Enceladus in near future....

While recycling would be good for the vast majority of the water needs, until the reclamation technology is better we would need an exterior source of H2O.
In orbit, capturing an ice asteroid and slowly mining it would suffice. On a celestial body that would entail some sort of ice nearby or a mining station near ice piping water to the colony.

But how much of this ice in Ice Asteroid is actual water? Considering near absolute zero temperature, every possible gas is part of icecap. Aren't recent landing at 67P/Churyumov–Gerasimenko concluded, that asteroids/comets are mostly hollow, and most of ice already evaporated during millions of years?

that´s why i think the best currently known water deposit is the Enceladus...
