Hi my name is Vince. Been a 20+ year pool owner. The more I learn, the more I realize how much I don't know, especially about pools. Just put in a new liner for two reasons: 1- the obvious, a new liner was needed (10+ years old), 2 - had some serious black staining so instead of chasing it thought it better to dump the water and do it all over again.

I am here because all the pool experts, the stores, the free-lancers, the independents that I have come across were really not able to help me with my issue(s). As we speak the pool is filling and I am looking to start up the pool in a correct and efficient way with the help of all of you here.

First question: I am filling the pool with well water. What is the best way to test for iron and etc.? (my conclusion is that my black stains were copper, from using copper based algaecides).

Any help is greatly appreciated!
 
Welcome to the forum!
Have you had your fill water tested for iron?
When you add chlorine, the water will turn green, yellow, or brown, that will be iron. Get polyfill to use in the skimmers to filter it out. Have you checked your sand filter? It may be full of iron.
Otherwise, do not use any more algaecides. Add CYA granules using the sock method as you fill the pool targeting 40 ppm. Add liquid chlorine to achieve 3ppm FC. Once the pool is full, add the salt. Test the pH, TA, and CH. Adjust pH if necessary. Get your (undersized) SWCG going and then raise your CYA to 70 ppm.
Follow the FC/CYA Levels
I suggest you read ABC's of Pool Water Chemistry and consider reviewing the entire Pool School eBook.
 
Thank you for your response.

I did have my well water tested about over 10 years, and I cannot locate that report. Not only since that report we have a new well pump and is it located deeper into the well. So I'll need to do another one. Takes about 6 weeks, but in the interim I would like to see where it is. An indicator is that the pool did not/does not have rust staining, the lawn sprinklers are connected before the water conditioner. At this point there are no stains on the house, the sidewalks or the driveway.

Are sequestering agent recommended?

I have looked at the ABC's and have been reading lots on the site and looking at videos. I will move into the eBook next. Also, you mentioned that the SWG was undersized, the IC40 is up to 40,000 gallons. Why the bigger one?
 
Hi Vilo
there are test kits on the market which can test for metal in the water. Unfortunately they are a bit pricey at 100$ or a little more. Due to the cost of those kits, and the seldom need to use them, most of us here at TFP dont recommend to buy one.

As much as we dont like pool store testing, their tests generally include metal testing. Though however much ppm the results show may be subject to accuracy, it will at least tell you if its present or not, in any significant amount. So, it might be worth running a jar of water to the pool store to have it tested for the presence of iron.
