Salt Water Pool With High Chlorine & Rust Colored Water
We have just purchased a 54" X 21" salt water system pool. After filling up the pool, we brought a sample to the company and they gave us the directions.
After having done all that, I ran a test and got a high chlorine reading "almost 3.5 perhaps" and a low PH "about 7.0 or 7.1 (difficult to determine with the test kit).
I will get the one you suggested but meanwhile, my water is rusty color. Short of draining water to put some more (we don't have that alternative with the well being low (eastern Ontario). I said to my freaked out husband to just let it be and it will come down - I shut off the salt system / chlorine generating device and we wait.
From what I read of some of your answers, it should be right.
Thanks for the question Robin
The chlorine reading is fine. Home pools should run the chlorine between 1.5 - 3.5ppm. You're on the upper high side, but nothing to worry about. I run the Y pool (80,000 gallon salt pool) between 3.5 - 4.5ppm and it's fine.
It will take some time to learn how to "dial in" the salt chlorinator. This will be determined by usage, sun, heat, organic matter that falls into the pool (grass, leaves, etc..)
Most salt pools with normal use will keep it around
20 - 25%. You might be able to start from there and work your way around that. Next, the pH is a bit low, but nothing that a little baking soda won't cure.
You can also use 20 Mule Team Borax as this will raise the pH without much happening to the alkalinity.

I'd like to have the rest of your chemical readings. It makes troubleshooting much easier and the process of clearing up your pool will go much faster. With well water you probably have high iron and/or copper. You need to get this checked out from your local pool store.
If you do have a high metal content, you'll need a good metal sequestrant. A metal sequestrant does not remove metal from pool water. It holds it in solution until it can get filtered. Then you backwash the metal out. Because metal sequestrants break down over time and get filtered and backwashed out, you need to weekly dose your pool if you have high iron and copper.
Metal sequestrants that are based on HEDP, phosphonic acid or something similar are the most effective. Jack's Magic Blue, Purple, and Pink Pink Stuff, Metal Magic, Metal Free, & Metal Klear are very good. Yes, I would suggest getting a Taylor DPD kit.

Hope this helps and have a great Summer.
