High Iron and Copper

Postby nymickey » Sun 22 Mar, 2020 11:35

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
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

With a CYA of 40 in a SWCG pool it's to low and needs increasing it to 70 with a chlorine target of 5 as indicated in Chlorine / CYA Chart
Recommended Pool Levels
Your salt also seems to low as most need about 3000, check your SWCG recommended level
Your ph could also come down a bit but don't do anything untill you have added more CYA as that will reduce it
Use Pool Maths to work out quantities
