Algae is not harmful to swimmers per se, but pools with algae may also be a safe harbor for pathogens like E-coli bacteria. Algae create a chlorine demand in the water for itself, consuming chlorine that should be working on other contaminants. As it expels carbon dioxide, the pH level of pool water can rise.

While shocking and adding algaecide is effective in getting rid of algae, it should not be done together. This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.

What happens if you put too much algaecide in your pool?

The presence of too much algaecide can lead to a foamy pool water. Air pockets within the filter system can cause bubbles on the pool surface as well. The bubbles and foam resulting from too much algaecide will be much smaller in size.

Is shock and chlorine the same thing?

1) What is the difference between chlorine and shock? Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly. Chlorine tabs (placed in a chlorinator, floater, or skimmer basket) maintain a chlorine residual in the water. You do need to use both tabs and shock.

What does black beard algae look like in water?

As time passes, the black beard algae looks more like three-day growth… But if left unattended, it soon grows into a glorious, thick and brushy, hair jungle. Seriously, it looks like hair straight out of a shampoo commercial! Like most algae, black beard algae draws its nutrients from the water.

Why are beard algae not good for the environment?

Perhaps the number one cause is unstable or low levels of carbon dioxide. When CO2 is unstable, plants can’t use the fertilizers and light available to undergo photosynthesis, and that kind of environment is a hospitable one for beard algae. In that case, supplementing CO2 supplementation is likely required.

What’s the best way to remove black beard algae?

Then I stumbled across a video on YouTube (you can view it at the bottom of our post, Black Beard Algae – The Battle Begins) and decided to give this method a shot before starting over. We used a 50/50 mixture of 3% hydrogen peroxide and Seachem Flourish Excel.
