    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.

    Some swimming pool suppliers provide commercial products that can be used for thorough cleaning. Ceramic tile or vinyl cleaner that is not too abrasive can effectively remove stains from fiberglass pools, especially if the pool has minor stains and is cleaned regularly, these cleaners can work well. Oxalic acid also helps to remove fiberglass pool stains. However, the substance can make the pool water cloudy for a few days. Swimming pool suppliers also have many industrial products that can be used to clean the pool. Atlantic Pool and Spa have a number of products and methods that will keep your fiberglass pool looking its best.

    Add Metal Sequestrate In Your Pool Water

    Metal sequestrate should be the last option to use in a pool because it works differently from metal removers like Metal Magic and Orendas SC-100. Metal sequestrate does not remove metals in your pool water. Still, it naturally binds to the metals, holding metal particles together in your water so that they don’t come out of the solution to react with chlorine when added to your water or when pH levels get too high.

    Ideally, regular doses of sequestrants will prevent metal staining when chlorine is added into the water and slowly break down. Therefore, they should be introduced regularly in your pool water to maintain the right level to keep stains away.

    The most effective sequestrants are derived from phosphoric acid, and the best in the market today is Pool Mate Metal Out. This product helps prevent discoloration of pool water from iron, silver, manganese, copper, and other metals and minerals that may be present in the water supply.

    Pool Mate Metal Out is an excellent general-purpose sequestrant that helps protect plumbing and pool walls from rust, stain, and scale. It should be used for pool openings and closings and throughout the season. For best results, add 1 quart per 10,000 gallons weekly, and you will never have metal stains in your pool.

    Keep The Pool Surface Clean

    There are some different types of automatic pool cleaners but the robotic pool cleaner is pretty much like a Roomba for your pool .

    Its the best cleaner for mustard algae blooms because it does the best job at picking up fine, silty debris.

    If you have trouble with this type of algae, this is definitely something I recommend using.

    Common Sources Of Pool Stains

    Algae can tint the pool water and also speckle the surface. The three most common algae types are described by their respective colors green, black or yellow .

    Metals, such as iron and copper, are found naturally in water and their presence can be compounded by leaching from other sources such as residential plumbing, fertilizers, and pesticides. Copper also comes from pool heaters which often have copper heat exchangers, and from pool algaecides.

    The issue with metals is that water evaporates but metal does not, so the concentration of metals builds over time. When the saturation point is reached, the pool water is not able to contain additional metal. This is when metals begin to cleave to the pool surface and form stains. Sequestering agents can help to keep metals in suspension to prevent staining but are not sufficient in some cases.
