How to Identify and Treat Swimming Pool Stains
Stains are very common in swimming pools but they ruin the aesthetic of your space and can be off-putting to swimmers. The good news is that many stains are very easy to remove with basic pool cleaning equipment, so read on to find out more about the diagnosis and treatment techniques you can use in your pool at home.
Work Out the Cause of Your Stain
If you?re not sure what?s caused your pool stain, the easiest way to work it out is based on the colour.
- Green and brown stains ? these are most likely to be caused by organic matter such as leaves, mud, worms or other wildlife
- Red and blue stains ? most commonly caused by brightly coloured berries
- Blue/green/black stains ? likely to be caused by copper if there is no obvious build-up of organic matter
- Rusty brown/red stains ? this indicates contamination by iron
- Brown/black/purple stains ? suggests manganese is the likely culprit
If you can?t work out what has caused your stain then you can buy a water testing kit that will test for the presence of common metals, or you can bring in a sample to Maple Pools for a free water test.
Removing Organic Stains from Your Pool
The first step in removing organic stains is to get rid of any remaining debris. Clean the surface of your pool with a pool skimmer and a vacuum cleaner for the bottom and sides. Once your pool is clean of solid waste, you can shock the pool with a chlorine treatment which will usually get rid of the stain almost instantly. Use a stiff brush to scrub your pool after over-chlorinating the water and it should look good as new! For stains around the water line, you can use an enzyme-based cleaner which will eat away at the unwanted organic material, thereby removing the stain for you.
Removing Metal Pool Stains
Metal stains can often be tackled using an ascorbic-acid based stain remover. Ascorbic acid is the chemical name for Vitamin C, so if you want to test whether it works before investing in a cleaning product you can try rubbing a Vitamin C tablet over the affected area and see if it lightens the stain!
Whatever chemicals you choose to use to get rid of your staining, you?ll need to vigorously scrub the affected area in order to make sure all of the offending substance is removed. Some persistent metal stains will need to be formally identified and removed by professional pool cleaners.
Preventing Future Stain Build Up
The best way to avoid pool staining is simply by taking good care of your pool on a regular basis. Use a pool cover, skimmer and vacuum to avoid any build-up of organic matter and maintain your pool?s chemical balance to counteract the effects of any stray metal compounds. Make sure your swimming pool components and equipment are in good repair as when any metal parts begin to get old they can start to rust and infect your whole pool.
