What is Pool Algae?

Pool algae are residing organisms that contain chlorophyll and use photosynthesis to grow. It’s not technically classified as a plant; however, it may be most intently recognized that way due to how it grows and multiples. 

Algae is regularly idea to linger in warm, darkish locations. However, it indeed prospers extra in the daylight. It also needs food to survive and finds nourishment in all sorts of contaminants. Some examples could be debris, dissolved splendor merchandise, and dust.

Algae can acquire in swimming pools by being introduced. However, its touch is nearly constantly a gift, seeking a chance to connect to something and bloom. That’s why chlorine and pH degrees are crucial in proper pool preservation. It continues those spores at bay, giving them little opportunity to grow.

Of course, you might be questioning why it matters. After all, algae itself by no means harm each person, proper? 

Well…Kind of.

While algae itself isn’t always, in reality, dangerous to swimmers, it does generally tend to hold directly to bacteria that make your water unhealthy.

Since algae prosper on particles and waste, you may believe what varieties of matters can lurk there. To call just a few, fecal be counted, blood, mucus, and saliva.

Unpleasant, I recognize. 

And within those pieces of being counted and fluids can live a whole host of microorganisms. E. Coli, giardia, legionella, shigella, campylobacter, and salmonella are only some. 

A properly-balanced pool with the correct quantity of chlorine commonly takes care of the terrible stuff. However, algae can cling directly to it. Not to tell the truth that algae also use chlorine, making it nearly impossible to balance. 

And when you permit tiny algae to start to make its home in your pool, it’s going to unfold and develop and speedy takeover. That’s when you have a real mess for your fingers.
