I am a new pool owner and new to this website as well. So please bear with me.
I opened my, round above ground, pool with an experienced friend last week. The water was sparkling clean but was a bit acidic. We shocked the water and I waited few days before I went to the pool store yesterday and got them to test the water. They wanted me to add Calcium and increase the pH also they recommended adding stabilizer since free Chlorine levels were low. I added the stuff and pool turned cloudy right a way. I called the pool store and they told me the cloudiness will go away quickly. I let the pump work overnight and this morning it is still cloudy. The sand filter pressure level has raised to 20 psi (it was around 12 last night). Also when I turned the pump off, I can see most of the cloudiness is accumulated at the centre of the pool. I measured the pH this morning and it is obviously too high.
Am I facing calcium scaling here? or is it other problems that I caused myself?
Thanks for advice in advance
