If you recently found a flaky white substance in your saltwater pool and have cartridge filter what could this be?

Calcium deposits are a common problem in saltwater pools. They can form on the walls, floor, and equipment of the pool, and can make the water cloudy and difficult to see through. Calcium deposits are caused by the high calcium content of saltwater. When the calcium in the water comes into contact with the air, it forms a white, flaky substance.

Scale

Scale is another common problem in saltwater pools. It is a hard, crusty deposit that can form on the walls, floor, and equipment of the pool. Scale is caused by the build-up of minerals in the water, such as calcium, magnesium, and iron.

Algae

Algae is a plant that can grow in saltwater pools. It can form a green, slimy film on the walls, floor, and equipment of the pool. Algae is caused by a lack of chlorine in the water.

Other debris

Other debris, such as leaves, dirt, and pollen, can also get into saltwater pools and make the water cloudy.
