Your pool water is likely to foam if it has a low calcium hardness, because foamy water is more likely to form in soft water. If your pool’s calcium hardness is low, I suggest adding calcium chloride to raise the levels and prevent foam. The second most common reason for pool foam is low calcium levels.
What does it mean when your pool water is foamy?
This indicates that there is a high organic load in the water, which can lead to foam. There is more organic material than can be dissolved or eliminated by sanitizer in the water. This results in a “thickening” of the water.
Will pool foam go away?
It’s good news that dealing with pool foam isn’t difficult, but the process can take a long time. It all comes down to the original cause of the foam. After a few days, if it was caused by cheap chemicals like algaecide or other algaecide, it will usually dissipate on its own.
Is pool shock the same as chlorine?
As a sanitizer, chlorine is required to keep a pool clear and healthy (unless you use Baquacil products). Chlorine shock is a high-concentration chlorine solution used to quickly raise the chlorine level in your pool.
