From what i understand the hundreds of ceramic balls inside the rubbery ball increase the ph level of the water when they move around in the washer.
Sanitize ceramic ball.
This makes them ideal for use in developing countries and portable ceramic filters are commonly used in backpacking.
The final grounded particle size will be 1 1000 or 1 10000 of the ball diameter.
Ceramic water filters cwf are an inexpensive and effective type of water filter that rely on the small pore size of ceramic material to filter dirt debris and bacteria out of water.
Just like with an undergravel filter it is the lack of proper maintenance that turns them into a nitrate factory.
Wash and dry one section of the floor at a time.
If you periodically rinse them off and keep them clean nitrate and bio balls woes should decrease as long as this is the sole source of the nitrate problem in the aquarium.
Whats the standard cleaning process.
Use this method on wood tile floors which are made of ceramic or porcelain tile designed to resemble wood.
They help reduce negative ions in the water creating a natural hydrogen peroxide type effect which adheres to dirt to keep the clothes cleaner and fresher during the wash.
It is not the bio balls in a wet dry trickle or other type of inert biological filter that go bad.
Clean ceramic tile floors with warm water or a mixture of warm water and a few drops of mild dish soap.
Also the balls are agate ceramic type.
Add fresh water frequently to avoid cleaning with dirty water.
