How To Diagnose and Remove Any Swimming Pool Stain

A cool pool is a great escape from the summer heat.A dirty pool can cause a damper on the fun and keep people out of the pool.Regular maintenance is required to keep the pool free of stains.Sometimes it can be fairly easy to get rid of stains, but other times they can take a bit more than a simple scrub.The organic material left in the pool can cause pool stains on the wall or floor.The first thing to look out for is the color of the pool stain.

Step 1: Determine the cause of your pool stain by looking at its color.

Identifying the stain colors that appear in pools will lead you in the right direction for treatment.Depending on the cause of the stain, you will need a removal plan.There are two main stain categories, metal and organic, which come in a variety of colors.The combinations include green-brown, red-blue, blue-green-black, green, brown-red, and purple.If you can’t tell which color combination your stain is, it’s probably not a good stain.

Step 2: There are organic stains on the pool floor.

If allowed to settle on the pool surface, leaves, berries, algae, worms, dead animals, and other organic debris will leave stains.They will sink down and begin to decay on the pool’s floor if they aren’t removed immediately.It is easy to remove organic stains.Green, brown, or bluish-purple are some of the organic stains.If you can see leaves at the bottom of the pool floor, you may be able to spot organic stains.Try applying a small amount of chlorine to the stain.An organic stain will be easier to remove with a soft head brush than a metal stain.

Step 3: There are metal based stains.

Substances can be introduced into pools from well water or copper pipes.Major stains can only be caused by the oxidation of copper from the size of a penny.The types of metals that can be found in your pool are rust, manganese, iron, and copper.If there are rust colored stains on the pool wall below a ladder, it’s probably a metal and you should check the ladder for damage.Check under the lip of the pool, near the stairs, and around the drain.The metals in your pool water can cause stains that are reddish brown or very dark.Some metals cause pool stains.There are copper and brass pipes.There will be blue, green, teal, black or dark purple stains.There are rusty brown, gray or greenish-brown stains when iron is from well water.There will be pink, dark brownish-black or purple stains from well water.White crystals of calcium can be seen from plaster, grout, mortar, or cal-hypo chlorine shock.If you have a metal based stain, it is important to know which metal is causing you problems in order to properly treat it.Improper chemical maintenance is a common cause of blue-green copper pool stains.The copper heat exchanger can be damaged by low pH and high chlorine levels.It’s easier to keep metal stains from developing with proper water balance.

Step 4: Seek assistance from a professional.

Use your yellow pages to find pool specialists or pool retailers in your area, if you want to leave the stain removal to the experts.You will need to take a pool sample to their location so they can test your water and determine what kind of metals are in it.A special Additive can be used to remove metal stains.

Step 5: You need to take a water sample for a diagnosis.

The opening of the pool should be facing the floor if you hold the cup upside down.You can collect the water sample by pushing it under water.Take the sample away from the jets or skimmer openings.The sample should be taken from the middle of the pool.To get the most accurate test results, get as close to the middle as you can.

Step 6: As part of your regular testing, make sure you perform a TOTAL metal test.

Free metal testing only measures non-sequestered metals, while total metal tests measure all the metal in your water sample.

Step 7: To test the water at home, use test strips.

You can take a water sample from the pool.Take a dry test strip and dip it into the water.If you don’t shake off the excess water, hold it in the air for 15 seconds.To get your readings, you will need to match the colors of the strip to the back of a bottle.There are many different types of test strips you can buy, but you only need to check for free chlorine, pH and alkalinity.Test strips should be used at least once a week.When opening and closing your pool, bring a sample to your local pool store once a month to have it professionally checked.

Step 8: You can try a liquid test kit.

For a home pool, you can use pH and chlorine or phenol red and OTO chlorine test kits.Liquid tests kit can be very accurate, but you have to be able to translate the results.Depending on how bright or dark the water is, you have to match the chemicals to the directions on the package for a proper treatment plan.It can be hard to decipher the different colors.OTO chlorine is a test for total chlorine.You add a yellow liquid to your sample.The more yellow the pool water is.If you add phenol red to a small sample of water, you can check the pH balance.The higher the pH balance is, the more red the water is.It’s hard to see the low end of the colors with a liquid test kit.You should use a white background to look at the colors.

Step 9: Determine if the problem is your fill water.

Before filling your pool, test the water directly.If you find high amounts of metals in the water, you can drain your swimming pool and refill it with softened water.You will need to have the water re-tested after 48 hours.Continue the process if there is still a high concentration of metals.If your pool water is corrosive, metals are most likely being introduced into it.Make sure pool equipment isn’t leaking metals into your pool water by checking it.

Step 10: The organic materials need to be removed from the pool surface.

The greenish-brown stains are related to something that was left on the pool floor.As part of the treatment, these substances need to be removed.When it comes to removing organic pool stains, you can usually do it, but with time, your pool will start to have a dull, light-brown color that you won’t be able to remove.It can be hard to notice the brown color at first.If you have trees that hang over your pool, watch for leaves, branches, or fruit that may fall into the water.A pool skimmer can be used to clean the pool.Any organic debris that floats to the bottom of your pool needs to be removed with a pool vacuum.An automatic pool vacuum that uses a sensor can be used.

Step 11: It’s a good idea to acid wash your pool.

If your pool has a plaster liner, you can drain the pool water and wash it with acid.The stripping of a thin layer of pool plaster is not something that you can practice all of the time.The bright white surface needs to be washed every five years.

Step 12: The stiff scrub brush can help remove stains.

There are greenish-brown colored stains that build up from organic stains.You might want to try an enzyme based pool chemical.Natural pool enzymes will eat away at organic material to remove the pool stain with little or no scrubbing and without the use of harsh chemicals that damage pool liners.If your stain is all around the waterline of the pool because of material floating at the top, an enzyme-based cleaner will help to break down organic compounds and oils by speeding up the chemical reactions that assist in making stains disappear on their own.To make sure you have all the debris and oil left, follow up with a thorough brushing.

Step 13: If you have a pool, shock it with chlorine.

The best way to deal with organic stains is tochlorinate the water and give it a good brushing.You can use a stiff brush to get around the pool.Try pouring a small amount of chlorine shock over the stain to make it disappear.Don’t try this on a vinyl pool because it could remove the liner pattern, it works great on plaster pools.The water needs to be tested to make sure the balances are where they should be.The alkalinity should be between 100 and 150 parts per million.

Step 14: The stains should be removed with a scrub brush and muriatic acid.

The acid should be poured into a piece of pipe and delivered to a stain on the pool wall.If the whole pool is stained, you may end up with a bright white spot that is surrounded by a darker color.Before you use your stain removing product, make sure you shock the pool so that you have enough chlorine in the water.

Step 15: Use an abrasive scrub to avoid harsh chemicals.

If you want to get in between cracks, try a tile grout scrubber.There are two types of heads.One is for a concrete pool and the other is a vinyl pool, so make sure you check which one is right for you.You can attach it to your pool pole to remove pool stains if you have it.

Step 16: The proper way to get rid of metal in a pool is by taking the proper steps.

There is a metal removal product that can be purchased for up to a month.The first step of most stain removal processes is this one.Ask a pool professional which size is best for your situation, as there are many sizes that offer different degrees of strength.

Step 17: All machines and pool equipment should be turned off.

Chlorinators, metal ionizers, generators, UV systems, and ozone generators are included.During the process of stain removal and heavy chemical treatments, it is best to avoid water contact with pool heaters, chlorine generators, and other non-filtration systems that are near your pool.

Step 18: The chlorine level in your pool should be between 0 and 2 parts per million.

The lower the chlorine level, the less ascorbic acid you need to clean your pool.If time is a factor, you can add salt to the water, following the manufacturer’s instructions, if you wait for the chlorine level to drop naturally.Algaecide can be added to the pool water.You need to follow the instructions on the box regarding how much you need for your pool.The lowered chlorine levels prevent the growth of algae.

Step 19: Ascorbic acid can be used to remove metal stains.

If you believe your pool stain is related to metals or if the suggestions above for organic pool stains do not improve your stain, try ascorbic acid based pool products.If you want to use a home method, crush up the vitamins and rub them against the stain.Check to see if it lightens after a few minutes.If you want to treat iron stains, keep in mind that ascorbic acid is the best choice.Sprinkle ascorbic acid over the surface of the water to treat large stains.Start by using 1/2 pound of ascorbic acid per 10,000 gallons of water.Put the filter on “circulate” and turn it on.For a half-hour, allow the ascorbic acid to work.If the stains are gone, check the pool.If they’re still there, add more ascorbic acid and let the filter circulate the treatment for another half-hour.When the pool is clean, repeat this process.

Step 20: The pool water has a chemical balance.

The size of the pool determines the appropriate range for the pH, alkalinity and hardness levels.Automatic chlorinators, chlorine generators, UV systems, and ozone generators should be turned on.To keep metal levels low and help maintain a stain-free pool, place a metal eliminator pack in the skimmer basket or pump basket.

Step 21: It’s a good idea to make pool maintenance a regular occurrence.

Stain removal and cures are more difficult to maintain than prevention.You can get a sample of your pool water tested by a professional or you can use an at home kit.If you fill your pool from a source other than “city water” you should also test the fill water because well water carries a lot of iron that can leave behind stains.Every week, do small shock treatments.It’s a good idea to scrub the bottom of your pool several times a week.

Step 22: It’s a good idea to prevent metallic stains from returning.

If you have a metallic pool, you should make sure to regularly test your water for metals.You can add fill water to your swimming pool or they can be introduced into the pool water through the use of pool equipment or plumbing.It is important to keep an eye on metal levels.Use sequestering agents.They tie-up minerals in a solution to keep them out of the water.It’s a good idea to make sure they don’t have phosphonic acids as they can cause an algae outbreak.There are disposable absorbent bags that remove and eliminate metals.Drop one into the skimmer basket or pump basket and it will absorb metals.

Step 23: Keeping your pool water free of natural debris is a way to keep organic pool stains out.

You can either skim your pool or use an automatic pool vacuum.You can use a winter pool cover when you don’t use your pool.Mudslides can cause dark pool staining.If you can’t prevent these materials from entering your pool, try covering it with a dark colored plaster or liner to hide the stains.
