We all love a good swim in the afternoon or during the summer season. But what will happen to our pool after winter? We should always expect for the unexpected - Stains! How do we deal with this? Learn more about stains on your pool and check the following simple tips and tricks of keeping it clean.

Identify the cause of your pool stain. If you see leaves in your pool, then the stain may be caused by something organic. The stains on your pool may be caused by leaves which are usually greenish and with an algae-like appearance. If, however, you see a reddish brown stain on your pool then it is probably caused by rust and the source can be a metal and you have to study this issue very well as this not just look nasty but rust stains, if not treated as soon as possible, may cause other deleterious effects on your pool.

Next, is for you to remove these stains. Organic stains can be easily removed by scrubbing the surface hard with a brush and an organic cleaner. There are also available pool chemicals that contain enzymes which can actually destroy the source of the stain without having to scrub it. You just have to leave it there and let it do its job. This is much more preferable if you own a more luxurious pool which is sensitive to scrubbing.

To remove rust stains, which usually appear as reddish or brownish stains, you have to see what might have caused the stain. The metals which contain iron are the ones responsible for these rust stains. However, other metals such as manganese and copper may also corrode and will result in a different stain. Example of the possible sources of rust stains on your pool are ladders, drain etc. Rust stains have to be addressed properly and as soon as possible. Try using rust removal products for these are proven effective against these stubborn stains. However, other acids in your pool may compete with your rust remover and what you have to do is to lower the acid concentration of your pool water (ask your pool technician how to do this) and let your product do its job.

Take preventive measures in order to remove these stains for good. This can be attained by having your pool water checked and evaluated for any presence of metal. You should remember that metals are part of our natural environment and thus they can be everywhere. So, you have to be sure that the water that you are filling your pool does not contain metal components as these can contribute largely to the staining of your pool. Rust staining can also be caused by pipes and pool plumbing which you use to fill up your pool, so you also have to be mindful of this. Prevention is proven better and effective than cure.

If you are sure that your pool has some stain issues, what you should do is to drain your pool at least halfway and refill it with treated water (softened water). Let this water circulate for about 2 days and have it tested the second time around for traces of metal components. Remember that if metal is introduced to your pool water, corrosion is very likely to happen. You should ask for the Total Dissolved Solid Levels or TDS level of your pool plus the pH and alkalinity range of your pool. If any of these test results exceed beyond the normal range, then the likelihood of corrosion t happen is very high. The result? The iron and other metals may leach from the pool surface and in to your pool surface and rust will form. Lastly, do not forget to de-chlorinate your pool once again in order to maintain the cleanliness of your pool.
