5 Things to Know About Pool-Spa Foam

Foam is a symptom, not the problem The jets aerate the water, and if your chemistry is off, you get a bubble bath. Fix the underlying cause, not just the foam.

Phosphates are the most common cause They enter from body oils, lotions, sunscreen, and some pool chemicals. Phosphates act like soap and stabilize bubbles.

Use a phosphate remover A product like Orenda or SeaKlear usually clears foam in one treatment. Fix the phosphates, and the foam disappears on its own.

Check calcium hardness and total dissolved solids Low calcium and high TDS both make foam worse. Address these alongside phosphates for a lasting fix.

Do not just add a defoamer That masks the problem for a day. Get the chemistry right so the foam does not come back.
