Claim 14:
15. A pool chemical control apparatus comprising:
a pool comprising:
a circulating pump including:
a pump inlet;
a pump outlet; and
a pump conduit;

a filter unit including:
a filter inlet;

a filter outlet; and
a filter conduit;

a drain including:
a drain conduit;

a pool skimmer including:
a skimmer conduit; and

a pool return conduit;

a pool chemical hub (PCH) apparatus comprising:
a slab;
a base affixed to the slab;
a cover detachably connected to the base;
a PCH inlet;
a PCH outlet;
a PCH return conduit including:
a plurality of pool returns;

a chemical testing and introduction assembly including:
a water inlet;
a water outlet;
a water conduit having:
a plurality of chemical input ports;

a test loop conduit having:
an inlet control valve;
an outlet control valve; and
a plurality of chemical sensor ports disposed between the inlet and outlet control valves;

a plurality of pool chemical containers, each of the plurality of pool chemical containers including an inlet, an outlet, a conduit, a fluid level sensor, and a pool chemical;
a plurality of chemical sensors connected to the plurality of chemical sensor ports; and
a plurality of chemical introduction pumps connected to the plurality of chemical input ports and to the plurality of pool chemical container conduits;
a control unit including:
one or more output devices;
one or more input devices;
a processing unit in bidirectional communication with the inlet and outlet control valves, the plurality of chemical sensors, the plurality of chemical introduction pumps, the fluid level sensors, the one or more output devices, and the one or more input devices; and
a power supply configured to supply power to the processing unit, the inlet and outlet control valves, the plurality of chemical sensors, the plurality of chemical introduction pumps, and the fluid level sensors,, wherein:
the pool return conduit is connected to the drain conduit, the skimmer conduit, and the circulating pump inlet,
the circulating pump outlet is connected to the filter conduit,
the filter outlet is connected to the PCH inlet, the plurality of pool returns are connected to the PCH return conduit, the circulating pump circulates pool water from the pool through the pool skimmer, through the filter unit, through the PCH apparatus, through the PCH return conduit, and through the plurality of pool returns into the pool, and, wherein the processing unit is configured to, on a periodic time:
open the inlet control valve and the outlet control valve of the chemical testing and introduction assembly for a purge time to purge old pool water from the test loop conduit and to fill the test loop conduit with new pool water,
close the inlet control valve and the outlet control valve,
after a settle time, activate the plurality of chemical sensors,
receive sensor data from the plurality of chemical sensors regarding pool chemical values,
compare the sensor data to stored pool chemical values stored in a memory of the processing unit, and
if one or more of the pool chemical values fall outside of the stored pool chemical values, then:
(a) activate one or more of the plurality of chemical introduction pumps associated with the pool chemicals that need to be adjusted in the pool water, and
(b) introduce an amount of the needed pool chemicals at a desired rate into the pool water to adjust the pool chemical values.
