What causes suds in a pool?

* Soaps and detergents: These can come from a variety of sources, including bathers' swimwear, suntan lotion, and pool cleaners.

* Organic matter: This can include leaves, grass, and other debris that gets into the pool.

* Metals: Iron, copper, and other metals can react with chemicals in the pool water to produce suds.

* High pH: A high pH level can cause the water to become more alkaline, which can lead to suds formation.

* Air: Air can also cause suds if it is introduced into the pool water through a leak or a fountain.

Suds can be a nuisance, but they are not usually harmful. However, they can make the water look cloudy and unappealing, and they can also interfere with the effectiveness of pool chemicals.

If you see suds in your pool, you can try to remove them by skimming the surface of the water and then adding a defoaming agent. You can also try to prevent suds from forming by keeping the pool water clean and free of organic matter, and by using pool chemicals according to the manufacturer's instructions.
