Types of pool stains
Organic pool stainsIf you have ever left some leaves at the bottom of your swimming pool for a bit too long, you have most likely noted that even after getting rid of them, there are residues of brownish coloring left on the bottom of your swimming pool. This is a good example of an organic stain. Such pool stains are often as a result of algae, leaves, acorns, and other organic materials, which are left untouched in the pool for some time.
Metal stainsUsually identified by an oxidized color, metal stains may often occur due to metals in the water or even metals from pool equipment and ladders getting worn-out with age. Iron also causes problems, since it’s found in various pool heating pipes and also swimming pool chemicals and other pool related equipment and plumbing. You can run a quick vitamin C test to check for iron stains. Just take a vitamin C tablet and hold it against the stain. When the tablet dissolves, and the stain vanishes or lightens, it is likely due to iron in your swimming pool.
Treating pool stainsTreatment varies based on the type of stain. Performing a chlorine shock and hard scrubbing can get rid of organic pool stains. You can also find various enzymes that are made to assist with breaking down organic leftovers, which can help in the treatment organic stains. Metal stains aren’t quite as simple to deal with. Usually, they need a hard-hitting swimming pool chemical, which has an acid like diphosphonic or ascorbic. Using these pool stain removers to treat will work well when applied on the stain directly. If you find that your water source has metals, you will probably have to use metal sequestrants that bind metals and assist in preventing them from causing pool stains. There are various popular sequestrants available that can effectively treat stains, keep in mind that they do wear down in your swimming pool water after a while, so you should not keep adding them.
As with many pool problems, the best method of handling pool stains is prevention. Keeping your swimming pool clear of metals and organic remnants may be slightly challenging, but is usually worth the effort, as stains that go undetected are at times not realistically removable. If you examine your water for excess metals (usually at the source is the right place) and are diligent in getting rid of debris, you may probably detect and get rid of any pool stain issues before they happen.
