Balance The Pools Chemicals

Remove Stains From Pool in 60 seconds

When the pools pH is high and the pool is thus basic , algae will thrive in it. You should thus keep the pH of the pool about 7.4. Besides this, you need to maintain the chlorine level between 2 and 4 ppm besides many other chemical balances. You should have a pool-testing kit to help you find the right chemical balance for your pool.

Brush The Sides And Bottom Of The Pool

You then brush the sides and floor of the swimming pool to loosen up the algae and other types of debris stuck on the walls and the floor. The type of brush you use will depend on the material used to make the floor and sides of the pool. Hard materials such as plaster or concrete will need a tough stiff or wire brush while softer materials such as vinyl will need softer brushes.

When brushing the inside of the pool, brush all parts including the ladders, walls, corners, steps, the floor and any other parts covered by the water. You may also need to brush the parts next to the pool to prevent debris from getting inside it.

Swimming Pool Stains Removal Guide

For some pool owners, a stained pool is beyond embarrassing, worse than tattered carpet and stained couch cushions. It can ruin your entire backyard experience. Hard-to-remove pool spots and stains can take a bit more than just brushing. You need some powerful methods to treat and prevent pool stains.

The first step to getting rid of those eyesore spots is to diagnose the stain type. Swimming pool stains can be caused by:

1. Metals or Minerals in the pool water coming out of solution2. Rust coming through the wall, floor, or around fittings3. Organic material like leaves, dirt, oils, worms or algae

A clue to identifying the type of pool stain may be found in the color of the stain.

Pool Stain Identification:

First of all, you should determine if the stain is Organic or Metallic.

Many people think that their pool plaster is stained, when they really just have an algae problem. If the stain brushes off, even slightly, or responds at all to shocking or sprinkling granular chlorine over it, then what you most likely have is an algae bloom. Visit our Pool Info page for more information on how to treat pool algae.

Mottling: Sometimes, you will not have a stain at all, but just normal mottling of the plaster. Remember that plaster is a natural product and is subject to variations in hue and shading. Streaks or mottled effects are considered natural, and they cannot be removed.

Chemical Solutions To The Staining Problem

For light copper and iron stains, BioGaurd Pool Magnet works well on “fresh” stains. For heavier staining, Jack’s Magic Blue Stuff is an effective additive which can also be used in higher chlorine levels, so treating metal in water that also has algae issues can be done at the same time. Products like these are sequestering agents that suspend the metals in solution to prevent them from “plating out” on the surface. As with stains caused by something organic, using an ascorbic or diphosphonic acid based product can help remove metal stains. When treating metal stains and discoloration with products such as these, the results may not be immediate and you may not see the stain lighten or be removed for several days or several weeks. The device discussed earlier that uses scrub pads and muriatic acid can also be effective on metal stains and shows instant results.

How To Prevent Metal Pool Stains

Itll take a little more vigilance, but you can keep metals from making your pool look ugly.

  • Test your water source for metals. If theyre present, use a hose filter when filling or refilling your pool.
  • Use a metal sequestrant in your pool. This chemical binds with metal particles to keep them from settling on pool surfaces, and to make it possible for them to be removed by the pool filter.
  • Maintain your pool plumbing. If any parts of it use copper pipes, check them regularly for corrosion, and replace them when necessary.
  • Keep the pH level in your pool steady. This is especially important if you have copper in your water. A low pH level will make the water acidic, which will corrode copper, which will oxidize it, which will stain your pool.

Important: A metal sequestrant is not a metal pool stain remover. It can help prevent stains by making it easier for metals to be removed from the water. But once you have a metal stain, a sequestrant will not remove it.

Finding a stain in your pool can be dismaying at first. But once youre able to identify the cause and the source of the stain, youll be able to easily remedy it. Then its just a matter of preventing future stains.

    Remove Metal Compounds From Your Fill

    Some years back, before the CuLator metal eliminator was available, there were no practical ways of removing metallic compounds from pool fill-water before entering your pool. The only possible way was to treat water inside your pool, which is hard work and expensive to maintain.

    CuLator Ultra Power Park is now my best option for this because you can use it in the skimmer or pump basket to remove up to 4 ppm metal compounds from 20,000 gallons of fill-water before entering your pool. If your pool is more than 20,000 gallons, you can increase your parks and use them both in the skimmer and pump basket.

    CuLator should work up to 30 days or longer depending on the metal level in your water and is replaceable once worn out.

    However, the easiest way to avoid stains in your pool is to avoid filling the water with metals. Before installing your pool, it is important to test your water source for metal content and avoid water sources with metals in it at all costs because maintenance will be relatively hard and expensive in the long run.

    Moreover, you need to be careful with the chemicals you add to your pool since copper may find its way in your pool from chemicals such as algaecide or ionizerand eroded pool parts with copper. If you cant use CuLator for any reason, detailed below are more ways to control metal stains in your pool.

    Chlorine Levels Too Low Adjust And Increase Chlorine Levels

    Raising pool chlorine levels can be much easier as compared to reducing the levels. Reasons that may cause the levels to reduce may include:

    • Insufficiently added chlorine
    • Cloudy/ murky/ milky water
    • Not testing enough

    To eliminate these problems, you may simply use chlorine tablets, granules, powder, or liquid shock to increase the amount.

    If the water looks murky, shock the pool and raise the levels to around 10 ppm, and wait for it to reduce naturally before swimming. If the water is clear, test and add just a tad bit more to maintain the 3 ppm standard.

    Whatever product you use, make sure you read the instructions on using the suitable amount according to your pool needs.

    Backwash the water and remove any waste from the bottom to ensure there is no chlorine loss in the pool.

    Make sure to use the sticks, tablets, or granules in the later afternoon or evening. This prevents any loss to sunlight, especially if the cyanuric acid concentration is low.

    Walk gradually around the pool deck and pour chlorine onto the sides. Run the circulatory pump for about 8 to 10 hours and never put chlorine directly into the skimmer.

    Remember, it is always better to start small and go up bit by bit to avoid over chlorinating the pool. Talk to our pool cleaning experts for more information on increasing chlorine amounts in your swimming pool.

    How To Clean A Fiberglass Waterline

    Cleaning a fiberglass pool along the waterline essentially means getting rid of the ring around the pool. The ring is formed due to metals that naturally occur in the water, combined with body oils and sun protection products that have been exposed to the water.

    You can get rid of this ring by adjusting the setting on your pool filter to make it work faster than normal. Once you have run the filter and the water becomes clearer, you can add more chlorine. This cleans debris from the water and sanitizes it. Be sure the filtration setting remains at 7.2 so that the water is safe to swim in, even during the cleaning process.
