green, cloudy water with white foam swirls

I have been trying to get the pool up and running for 2 wks now. Since I have well water, I always need to add iron out first. My current ph 7.4, free chlorine 2ppm, alkalinity is 100. stablizer is low. I was able to see the 2nd step yesterday through the light green water. I vaccumed, it stirred things up and now it looks like pea soup. There is a layer of white foamy swirls on top of the water now. I use powder plus shock. It is a 19,000gal fiberglass in-ground pool. I did put algecide in yesterday, foam today.

Any ideas would be appreciated.

Hi Rosie, and welcome to the forum!

The foam is almost certainly the algaecide unless it's polyquat 60, which is the only algaecide besides chlorine that we recommend here. If you don't put anymore of it in, the chlorine and your filter will gradually take care of what's there, but it might take some time. How "low" is your stabilizer? Have you shocked the pool yet? What minerals are you dealing with? I would assume you have iron, but what about copper?
