How to Balance a 16,000 Gallon Fiberglass Pool

I apologize on the front end if this is posted in the wrong place.

Greetings and Salutations,
I just had my water tested and the computer spit out the results below.
I think the water looks fine (we have a salt water generator) but the numbers do not look good at all.
Can you please advise what I need, the order that I do it and the timing of each chemical.

Gallons = 16,000
Filter = Sand
Type = Fiberglass
Free Chlorine = 1.12
Total Chlorine = 1.15
pH = 7.9
Total Alkalinity = 83
Calcium Hardness = 155
Cyanuric Acid = 43
Iron = .4
Copper = 1.3
Phosphates = 858
Salt = 1,807

What does your K-2006 test kit say?

We never make recommendations for chemical additions based on pool store testing.

But, the thing that jumps out at me is teh copper. Do you have a heater or have you used algecides in the water?
