How to Identify Pool Stains

How we identify pool stains

Correctly identifying pool stains is the most challenging part of what we do.  It also takes a lot of experience and visiting a lot of stained pools over many years.  Many different types of stains can appear to be very similar in colour.  However, the remedy needed to remove them can be very different.  For example, even experienced pool technicians will frequently misdiagnose algae stains.  This is one reason why we have more than 450 pool technicians as regular clients.   Also, many pool shops often suggest various expensive ‘all purpose’ stain removal products that have almost no effect. This is because they have no idea what the stain is and are using your money to test out different options.  One of the most common questions we are asked is how to identify pool stains.

The wrong treatments can make staining worse

In many cases, if stain products are not matched to the right type of stain it can make the stain even worse and harder to remove. Our customers often ask us to recommend the best stain remover product. The answer is the one that is right for your type of stain.  Remember, there is no single product that removes all types of stains.  So, don’t worry, after nearly a decade and 10,000 pools, we know how to identify pool stains and remove them.  Our process will save you a lot of time and wasted money experimenting with retail stain products that usually don’t work.
