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.
