    Black Algae: How to Get Rid of Unsightly Black Spots Swiftly and Effectively


    If you own a swimming pool and have recently noticed black spots appearing on the surface, the likelihood is that you may have a black algae problem. Black algae is one of the more resistant forms of algae; and as a result, it’s incredibly difficult to remove using DIY methods.


    However, with the right pool service professional help, these unsightly, problematic black spots can be removed, and with the right after-care, they are unlikely to ever make a return.


    Step 1: Identification


    Once you notice black spots appearing in your pool, take the time to observe the following things:


    Development. Have the spots developed at all; either growing in size or spreading across the surfaces of your pool? If so, there is a strong chance that it’s black algae.
    Texture. If possible, dive down and feel the surface of the spots with your fingers. If the spots are simply deterioration in the surface of the tiles, you should be able to detect this. However, if the surface of the spot feels in any way sticky, or tar-like, then this is a classic characteristic of black algae.

    Age. If your swimming pool is particularly old, it may be more susceptible to algae problems, particularly if the plaster is original.


    Step 2: Contact a professional pool maintenance company


    It’s inadvisable to attempt to tackle black algae by yourself, as it’s notoriously difficult to eradicate. This is due to the fact that the algae naturally protects itself in a water-repellent coating.


    Rather than attempting a DIY solution, get in contact with an expert pool maintenance company, who will examine the algae in greater detail and offer a practical solution to the problem, based on the surface and age of your pool.


    Step 3: What to expect during the treatment phase


    It is likely that the black algae will require chemical treatment in order to eradicate it completely, but first, your pool maintenance expert is likely to apply some sort of abrasive treatment to the surface (such as brushing) and apply an algaecide, in order to help break down the algae’s natural defenses and allow the chemicals to operate more effectively.


    The length of time that the process takes depends largely on how wide-spread and intense the algae problem is.


    Step 4: Preventing the return of black algae


    After the treatment, your pool will return to its former state, but it’s really important to make sure that you take steps to ensure it remains that way. Stagnant water is a major cause of black algae and it is vital to keep water well circulated and appropriately sanitized. Again, a pool maintenance service can assist with keeping your swimming pool in a clean, well maintained state, and regular pool servicing is highly recommended.


    If your swimming pool is currently suffering from a black algae problem, then don’t delay; take steps to resolve the problem as soon as possible, before the algae spreads any further!
