People who have experienced an outbreak of 'Black Spot' know only too well that it's a pool owner's nightmare!
You might think it's just a matter of pouring the right treatment into the water ... But it isn't that simple!
The chemicals used to eradicate black spot are quite strong. Safe when used correctly, they can be dangerous to humans. They can damage pool surfaces if not used correctly. The chemical balance of your pool water after treatment is critical for safe swimming.
'Black Spot' is an algal formation that starts life as a microscopic particle. Low chlorine levels in a 'winterized' pool, and sources of food remaining in the pool water (often in the form of phosphates), allow the formation of algae to 'bloom' in warmer water temperatures as the depth of winter passes.
Even if it's still too cold for us to swim, it can be warm enough for the algae to grow. The algal booming appears as small dark brown, or black, spots on the surfaces of your pool.

Winter has proven to be the best time to treat and eradicate 'Black Spot'. The pool's chlorine demand and water temperature are both at their lowest in winter, so algal growth is at its slowest.
