Thanks for all those info about the built up residual of the chlorine. I would not take a long term risk, I let the swimming pool discharge into the pond for now and I�ll solve that next year.
The fact is that the terrain is dead flat, I don�t have the levels measured by professional equipment and is very hard to find out by a simple look. So I didn�t plan a run-off channel in case the pond fills up to top. I expect to find out were to put a run-off for the pond as soon as I fill it, then I will make a kind of T joining the pool discharge into the same channel of the pond run-off.
Due to flat of the terrain, the lack of severe weather (he don�t have hurricanes nor tornados here), pretty stable rainfall average 4��/month, very small watershed area and high permeability of the top-soil I don�t expect a flood frequently (maybe once every other year), the run-off wasn�t my priority in the start of the project. In fact I expect to have to add well water frequently; most in the first years until the bottom gets impermeable naturally (experienced in other artificial ponds nearby).
I have 3 possible run-off alternatives/directions and I want to make sure to choose the lower one because I want to have the water level as high as possible.

Again thanks for your feedback.

PD: Is going to be a time to stock the pond, sadly we have a totally different fish species here in Buenos Aires. I saw plenty of good info in this forum about fish/structures.

Have a good weekend!
