Light brown stains from pool need suggestions

[SunnyOptimism]

I just opened pool about a week ago. Everything is still off. I put in some chlorine (maybe should not have and put in some metal free and the purple stuff). Pool has stains when opening on day 1.. copper was high at 2ppm and after dropping about 2foot of water and the effects of the chemicals.. it is now 0.3 according to test made myself and leslie pool staff. There is still some copper and the brown stains I believe can come off soon if after I get it balanced in PH, ALK, etc etc. Is draining the best way to remove copper in the pool (21,000 gallons) Chlorine is also way too high.. it is slowing going down now and yes I have the Taylor Kit 2006 . I have no heat exchangers but a liner pool and a lot of trees around and it rains a lot here contributing to the copper. Should I be worried of iron? He said there was no iron in there. I have the stain free ascorbic acid 4 lbs but did not use it first since I thought maybe get everything balance and then lastly is to remove the stains later... ideas?

Yeah, not to sound like "snarky" but blindly adding chemicals to a pool is really not a good idea. Also, your Cu is not gone, it's just masked. The 0.3ppm reading is simply lowered from 2.0ppm because of the Jack's purple stuff and MetalFree you added.

So here's my list of questions -

1. Are you using a Taylor K-2006 test kit? If so, can you post a full set of test results including CYA.

2. What "chlorine" did you add to the pool and what is your FC level?

3. What is you standard chlorination method (liquid chlorine, tablets, etc)?

4. Did you ever use Cu-based algaecides?

5. Can you please create a signature line with all of your pool details in it including your location?

The only way to remove metals completely is to drain and refill your pool. Since you have a vinyl liner, you CAN NOT fully drain your pool. The most you can drop the water line is 1 ft above the bottom of the shallow end. If reverse osmosis filtration is available in your area, then that could eliminate metals too, but it is typically only offered out here in the southwest.

If the brown stains persist after shocking your pool (remember, shock is process not a product), then it is either iron or copper. You'd have to perform a vitamin C test to see what you're dealing with. If they are metal stains, they can be removed by doing an ascorbic acid treatment but that is only going to put the metal ions into solution, not completely get rid of them.

So, before doing anything with the metal stains and metal in your water, your first mission is to get your pool water clean, clear and balanced. Then and only then can you properly deal with your metals.
