Lower The Free Chlorine Level To 00 Ppm
Before adding ascorbic acid, ensure that you take down the chlorine level to 0.0 ppm using a neutralizing chemical, direct sunlight, or partially draining and refilling your pool with fresh water. Lowering chlorine to 0.0 ppm is necessary, as chlorine will cause more stains, and you may need more ascorbic acid to clear the stains.
Important Note: Since clearing all-metal stains may take a couple of days with zero free chlorine, you can use ProTeam Polyquat 60 Algaecide. I recommend this because it has no copper compounds that may worsen the stains, has no ammonia that can cause extremely cloudy water that is not easy to clear and can effectively fight and prevent any algae that might thrive in your water.
How To Clean Organic Liner Stains

For more stubborn stains, try pool liner stain remover, or a stain eraser tool, both of which should be available at your local pool supply store.

Pool owners often complain about the green, slimy algae that accumulates at the bottom of their pool. These pesky pests cling to the walls and floor when water contains high levels of sunlight exposure, warm temperatures and higher pH values. The vinyl pool vacuum has become a more popular way to keep algae from growing in vinyl pools. The pool vacuum is the latest invention on the market, and its making waves for cleaning up green algae.
Black algae is just green algae filled with bacteria, and no cleaning is done for years. You may have to remove all the water from the pool first and then clean the pool liner. To get rid of black algae, you need to clean your pool regularly.
Yellow algae may sneak its way from the beach via your clothes or feet. Most of the time, they cluster on the pool liner and can also turn the pool water yellow. Dont worry, as they will hardly harm you.
Pink algae arent really algae. They are a form of bacteria that makes a colony on pool pipes and also end up on the liner. These are often dangerous for your health, and you need to clean them as soon as possible.

Stains Behind The Liner
Some stains are actually behind the liner, in between the wall or floor and the liner. They start as a bacterial colony or can be algae or mineral crystals. If they are dark enough and large enough, they may show through the somewhat opaque pool liner and appear as a stain.
Short of pulling up the liner and treating or patching the floor, and foaming the walls, what can you do when the stain seems to be behind or underneath the liner?
Start with the methods above: good water balance and give a heavy chlorine shock. This may only work temporarily. If the stains are near the waterline or high on the wall, you can lower the pool water and get at the wall with a scraper, then place a barrier in between the wall and the liner.

Get Ph And Alkalinity Back To Normal Levels
Ascorbic acid is strong and will definitely bring down pH and TA levels. If the pH and TA are not way out of balance, you can use 20 Mule Team Borax to raise the pH without affecting TA and an alkalinity increaser to bring the TA up to recommended levels when it gets low. Add these chemicals slowly while testing until they get to recommended levels since you dont want pH or TA to get out of balance.
Remember that pH should be maintained between 7.4 and 7.6 to avoid metal staining. I prefer using LaMotte ColorQ Pro 7 digital pool water test kit since it is very accurate and fast in taking all chemical readings. If you get your pH and TA out of balance by mistake or they get troublesome to balance, here is more about how you can balance pH and TA.
