What’s your first reaction when you hear the words “Black Friday?” If you’re anything like me, when you hear the words “Black Friday,” your eyes begin to dance, and your heart sings. Black Friday is more than just another day to find amazingly good deals on Holiday gifts. For me and people just like me, it’s an all out adventure.

Another adventure in its own right – yet doesn’t elicit the same results – black algae is perhaps the hardest type of algae to get rid of. There is, however, an art to removing Black Algae – and ensuring it never rears its ugly head again. Now, here’s what you need to know about certainly the most persistent, slimy, and potentially damaging algae.

What is Black Algae?

Black algae, the most aggressive form of algae, comes from the ocean. If it comes from the ocean how does it infect backyard pools? Good question! One of the most common ways for your pool to be infected by black algae is by a bathing suit that has once been in the ocean. It’ll only takes one time!

Black algae has very deep roots, and while it may start out small, chances are that it will grow into a much larger problem. Black algae has many layers. These layers protect it from normal shocking and algaecide. The roots of the black algae tend to anchor themselves into the sides of the pool plaster, making destroying it nearly impossible.

How to Get Rid of Black Algae

The best way to get rid of black algae is to attack it head on.

You will need:

  • A pool pole and brush
  • Chlorine tablets
  • Shock treatment
  • Gloves

I cannot stress the following information enough – it is the key to getting rid of black algae growth once and for all. Wearing heavy-duty gloves, rub ALL black algae spots with a chlorine tab in order to attack its head. You may want to consider draining your pool if the algae spots on the pool’s floor.

Your next step is to brush the heck out of your pool. Brush hard, brush thoroughly, brush often! You may notice a dirty looking cloud rise up while brushing. This is absolutely normal.

Triple shock your pool by adding three pounds of shock treatment for every 10,000 gallons of water your pool holds. Make sure to add the shock once the sun has set. Run your filter for a minimum of twenty-four hours after adding the shock. Brush three or four times beginning on the next day following treatment.

Tips for Preventing Black Algae

  • Always keep your pH, alkalinity, and sanitizer levels in the correct ranges.
  • Always run your pump/filter for 8 to 12 hours a day all year through.
  • Always keep your pool clean through regular vacuuming and brushing.
  • Always shock your pool once a week – 1 lb. of shock per 10,000 gals.
  • Always keep your pool equipment clean. This includes your pool toys, floats, ladders, diving boards, slides, solar covers, and of course your personal swimming suits.
