Acid
Drain your pool, then scrub the walls and floor with pool cleaner.
High calcium can causeSkin and eye irritationCloudy waterClogged pool filtersPoor filtrationCalcium build-up and corrosion on heatersScaling of the pool waterReally the only way to reduce calcium hardness is to partially drain the pool, 1/3, then refill. It may cause staining but that would be the least of your worries if you had a heater.
Are you using iodized salt or pool salt? I've read that the iodine in the iodized salt will leave yellow staining in the pool.
Improperly sanitized water or excessive rainfall can cause a low total alkalinity level in your pool. Low total alkalinity can cause pool staining, itchy and burning eyes and skin, and corrosion of metal parts in the pool.

How to treat this problem depends on several factors. First what type of pool surface do you have? Next what specific chemicals were used in the staining? How many gallons of water do you have in your pool? What type of sanitizer are you currently using in your pool? What is your complete balance including total alkalinity and calcium hardness? What color is the stain? What are the copper or iron levels in the pool water? Do you use well water? Is it treated or untreated? With these questions answered we can help formulate a solution to your problem. The best way to try to resolve this issue is to take a pool water sample along with a picture of the stains and show them to you local pool store. If you can find a store that sells a line of products made by Jack's Magic that would be best. Jack's Magic makes a line of stain removing chemicals and has complete processes to remove the stains.
First, find out what the stains are. Iron staining? Stain from using Morton System Saver salt pellets? Algae? Your pool service man should be able to tell you. Then take the appropriate action to remove - ask your local pool shop or pool service person.
Keep the acid content too high for a while and a lit of staining will tend to get bleached out.
To effectively remove metals from pool water, you can use a metal sequestrant or a chelating agent. These products bind to the metals in the water, preventing them from staining the pool surfaces. Regularly using a metal sequestrant and maintaining proper water chemistry can help keep your pool water free from metals.
Any iron in a swimming pool is likely to cause staining. Visit your local pool store and have it tested and based on the results of the test they can provide a sequestering agent to help remove the iron.
Acid reduces Ph So by adding potash you will neutralise the acid and regain the correct Ph
Brown staining on pool walls and fixtures is usually from a high iron content in the water. The chemical reaction with newly added fill water and the addition of chlorine shortly after will cause a fallout of this metal. I have witnessed this years ago after adding a gallon o f chlor. to a newly filled pool and just watched the brown cloud form and fill the pool to a chocolate brown color. There are chelating agents to prevent this from happening. k
