Just got our 1st pool It is a 33' AGP approximately 27,000 gal. We are on a well. So we filled the pool from our pond. Needless to say it is brown. I tested it and the only thing that registered was a ph of 6.2. I took a sample to the local pool place the next day for help. (Don't judge). The guy wouldn't even test the water because he knew what it was. He told me to start a 24 hr regime of 3 bags of shock, 3 chlorine tablets, and 3 caps of yellow Klear. Well after day 2 it might be a little lighter brown...maybe. The guy was arrogant. I was begging for help. He rambled real fast and then as I tried writing it down, told me there were several other customers there. I should have left the $170 worth of additional chemicals (not to mention the $6,600 for the pool) and walked out, but I needed to try something. Any thoughts? I tried the pool calculator initially, but it doesn't take into account the pond water and algae. I have read so much that I am confused. I don't even know if I'm going the right direction.
