Hello, I just had my above ground pool installed last summer. When I opened it this summer it was clear as could be but within a week there was a large black stain across the bottom of the liner that would not scrub off not matter how hard I tried. I went to my pool store and was told it was a copper stain from using Kleen Pool algicide. They have had me dumping lo and slow into the pool to reduce the PH level and claim once it is under 6 that the stain will magically lift and go back into solution. I have now bought 4 8 lb canisters of lo and slow to lower my PH and the stain does not appear to be lifting (although it may be getting lighter I'm not sure). My PH is now at 6.3 and my alkalinity is extremely low because of all of the lo and slow I have used. Please help, how can I get rid of this stain without continuing to buy the lo and slow and how can I prevent it from coming back again? Thank you in advance.

Welcome to TFP!!!:cop: Step away from the pool store with your wallet in your pocket
You can not remove a stain by just lower the pH ... and there are certainly better and cheaper products to lower the pH.
How big is the stain? Add pictures.
What test kit are you using?

So, do you see the problem with asking them to test your water and then telling you what you have to buy? Bit of a conflict of interest, or a fantastic business plan.
Well yes I guess I do. But I have not had a problem with them until this stain incident and just thought that is what people do. So that is why I am here for some help.

you have seen the light
get yourself a good test kit, that will allow you to take over your pool... The TF100 is a great test kit but you can also use the k2006, it just has less reagents.. The K2006C has more..
Add the xl option if you will be doing a slam, it has more of the reagents you will use.. also, the speed stir is "nice" to have but not required..

Newer copper stains can be removed using citric acid. However, you'll need to get the copper out of your pool and that will require either water replacement or ongoing use of a metal sequestrant product or short-term use of the CuLator product (contacting the company directly if it doesn't work initially; we've had mixed results but when they help directly it's been OK).
