New pool owner, just bought a house with an AG 15' x 30' pool.

Haven't been able to use it much after a big leak and patch problem. This morning my husband and I went to check on the pool so we could start up the never been used gas heater after a few chilly days so the kids can swim. We discovered the water is slightly cloudy and there is a light blueish greenish film on the water. My husband, who is the only one with pool experience but it was when he was a teen helping his parents, thinks it's from the alkalinity powder he put in the day before. We've never had this happen, the only things that are different are; the alkalinity powder, and we had hooked the gas heater up to test it out for the first time the day before, ran it for about 2 minutes, then turned it off since it was evening and we didn't want to lose the heat.

Originally, we discovered there might have been copper in the water, as the first time I went swimming my hair turned green. The previous owner had been using a Nature 2, which he explained as a wonderful device, and after my hair turned green I went online and discovered is not. LOL. We didn't hook up the Nature 2 when we opened the pool for the summer and due to a hole in the liner just two weeks ago, we ended up losing almost all of the water and refilling. The water was down to about a foot of water and we refilled. I was hoping that would take care of the copper problem as an added benefit.

We do have a chlorinator attached. (The second item we thought was some wonderful upgrade and we're starting to think isn't). On top of the blue green film, which is new, we have not been able to get the water right! I don't know why we're having such problems getting this pool running smoothly. I am getting so frustrated.

Is the light blueish greenish film from the alkalinity powder and will it harm the heater that I now have had running for about an hour? I have questions about the water quality, but I think I have to post those in another forum.
