My experience is that the stains will go away by themselves, through the effects of the chlorination of the water. Does not matter if the pool is a salt pool or fresh water pool. If the pool has a plaster finish, brushing the stains with a wire pool brush will speed up the process.
Green stains (copper color) that cannot be removed indicate you might have a pH problem. K
---- Water colors will change according to angle, distance and light. White, black, grey and blue plaster colors will give different shades of blue water reflections. Tan plaster colors will reflect green water. Green plaster colors will vary between emerald and blue. A light grey plaster color will be light blue grey on the steps and in the shallowest part of the pool. It will become a darker blue as the water gets deeper.In two words -"Gorgeous" and "Inviting"!
By far the easiest way without a professional cleaner is a product called Pool Cage Plus. (www.poolcageplus.com) Shoots 25 feet to get the top of the pool cage. And you don't have to do crazy things like your pool brush and scrub it.
I seriously doubt that the pool sweep is the problem here with your stains. You will have to describe the stains in order to get to the root of the problem. Are the stains: Rust color or brown? Black or gray? Green? Blue? Are the stains consistent or uniform? Are they all over the pool? Do they cover the whole pool or are they in small patches? Answer these questions and I may be able to tell you the cause. k
This must be an algaecide of some sort possible a low grade of chlorine. Did you follow the instructions EXACTLY? Is this product supposed to settle on algae spots? If not , did you brush it to keep it from clumping and settling on the bottom of the pool? The black stains, possible caused by the product burning the plaster where it settled --- improper use of product. Impossible to know without seeing the stains and finding out just how you used the product. Contact Bioguard for further info.
You drain the water then plaster the walls from inside

If your pool filter is up and running, also it is best to clean the walls and floor if you have a normal to high chlorine level because this will be also your cleaning agent. Take a soft bristle brush, get in the pool and start cleaning, all the above should come off. it is better if the filter is running so you can vac out the dirt, when the dirt goes to the bottom of the pool.
By allmeans install them now! Pool plaster contractors love to track them up with mud plaster and stuff.They cant see it from their house!From A Pool ContractorIn pool construction, the last item to be finished is the interior surface of the pool. This helps to protect the finish as well as allow time for the circulation, pump, filter and heater system installed since you will need to fill and run your pool immediately after the interior finish is applied. To plaster a pool you need to carry in 9000 pounds of bagged white cement, white sand and white crystal powder Then you mix an apply in to the pool surface in one day. It is exceedingly difficult to contain all of the white powder and cement from this process. The good news is that diluted muriatic acid will remove stains on your coping and deck.
