Water returning from the sequential filtration system passes through return jets below the surface. These are designed to impact turbulent flow as water enters the pool. This flow as a force is much less than the mass of water in the pool and takes the path of least pressure upward where eventually surface tension reforms it into a laminar flow at the surface.

As the returned water disturbs the surface, it creates a capillary wave. If the return jets are positioned correctly, this wave creates a circular motion within the surface tension of the water, allowing it to slowly circulate on the surface around the walls of the pool. Organic debris floating on the surface through this capillary wave circulation slowly passes through the mouth of the skimmer, where it is attracted due to the laminar flow and surface tension over the skimmer weir. In a well-designed pool, the circulation caused by disturbed return water helps remove organic debris from the pool surface and directs it to become trapped within the consecutive dilution system for easy disposal.

Some return jets are equipped with a rotating nozzle. Used correctly, it induces deeper circulation, further cleansing the water. Rotating the jet nozzles at an angle imparts rotation within the entire depth of the pool water. Left or right orientation would generate clockwise or counterclockwise rotation, respectively. This has the advantage of cleaning the bottom of the pool and slowly moving the sunken inorganic debris toward the main drain, where it is removed by the circulation pump basket strainer.

In a properly constructed pool, the rotation of water caused by the way it returns from the consecutive dilution system will reduce or even eliminate the need to vacuum the bottom. To obtain maximum rotational force in the main body of water, the consecutive dilution system must be as clean and unblocked as possible to allow maximum flow pressure from the pump. As the water rotates, it also disturbs organic debris in the lower layers of the water, forcing it to rise. The rotational force created by the pool's return jets is the most important part of cleaning the pool water and pushing organic debris through the mouth of the skimmer.

If the pool is designed and operated correctly, this circulation is visible and, over a period of time, reaches even the deepest end, inducing a low-velocity vortex over the main drain due to suction. Correct use of return jets is the most effective way to remove disinfection byproducts caused by deeper decomposing organic waste and deliver them to the consecutive dilution system for immediate disposal.

Mineral disinfectants

"Spa (Health)" Mineral Pool and Spa Disinfectants use minerals, metals or elements derived from the natural environment to produce water quality benefits that would otherwise occur with harsh chemicals or synthetics.

Companies cannot sell a mineral disinfectant in the United States unless it has been registered with the United States Environmental Protection Agency (EPA). Currently, two mineral disinfectants are registered with the EPA: one is a silver salt with a controlled release mechanism that is applied to calcium carbonate granules that help neutralize pH; the other uses a colloidal form of silver released into water from ceramic beads.[6]​.

Mineral technology takes advantage of the cleaning and filtration qualities of common substances. Silver and copper are well-known oligodynamic substances that are effective in destroying pathogens. Silver has been shown to be effective against harmful bacteria, viruses, protozoa and fungi. Copper is widely used as an algaecide.[7]​ Alumina, derived from aluminates, filters out harmful materials at a molecular level and can be used to control the delivery rate of desirable metals such as copper. Working through the pool or spa's filtration system, mineral sanitizers use combinations of these minerals to inhibit algae growth and remove contaminants.

Unlike chlorine or bromine, metals and minerals do not evaporate and do not degrade. Minerals can make water noticeably softer and, by replacing harsh chemicals in water, reduce the chance of red eyes, dry skin, and bad odors.

The density of fresh water is 1,000 kilograms per cubic meter, while the density of seawater varies between 1,020 and 1,030 kilograms per cubic meter.[8]​ Oil is less dense than fresh water and salt water, so it floats in both types of water,[9]​ but due to this difference in the density of water, the oil and fat particles, dispersed in the water, will reach the surface more quickly. in a saltwater or seawater pool,[10] being in both cases, the "only possible means" to eliminate them, to recirculate the surface water through skimmers.

A sequential filtering system is usually installed to remove organic waste in stages after passing through the skimmer. The waste material is trapped within one or more sieves of sequential skimmer baskets, each with a finer mesh to further dilute the size of the contaminant. Dilution here is defined as the action of making something finer in content.

The first basket is placed very close to the mouth of the skimmer. The second is connected to the circulation pump. Here 25% of the water drawn from the main drain at the bottom of the pool meets 75% drawn from the surface. The circulation pump strainer basket is easily accessible for maintenance and should be emptied daily. The third sieve is the sand unit. Here the smaller organic residues that have slipped through the previous sieves are trapped by the sand.

If not removed regularly, organic waste will continue to decompose and affect water quality. The dilution process allows organic waste to be easily removed. Ultimately, the sand screen can be backwashed to remove smaller trapped organic debris that otherwise leaches ammonia and other compounds into the recirculated water. These additional solutes eventually lead to the formation of disinfection byproducts (DBP). The sieve baskets are easily removed each day for cleaning, as is the sand unit, which should be backwashed at least once a week. A perfectly maintained consecutive dilution system dramatically reduces the buildup of chloramines and other DBPs. The water returned to the pool should have been cleaned of all organic debris larger than 10 microns in size.
