Should I use shock or algaecide first?

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 a pool?

The presence of too much algaecide can lead to a foamy pool water. Small bubbles will begin to be produced as the water is pushed through the return jet and back into the pool. Do not confuse these bubbles and foam with another common problem, which is air in your pool lines.

Should I run the filter after adding algaecide?

Add a dose of algaecide, bring your chlorine level high by shocking, and run the filter continuously until the problem clears. The next day you should vacuum up the dead algae and backwash your filter. Algae thrives in hot weather and in pools with low or no chlorine.
