We want to help you make informed
decisions before you buy. We do not promote one brand or product. We
want to educate and inform the general public of the large
selection of swimming pool supplies available to them today. Years
ago swimming pool owners did not have as many options available.

- IMPELLER The rotating member of a pump. The
part of the pump that moves the water.
INFLUENT The water entering the pump, the filter
or other equipment of space. Water going into the pump
is called in influent, while water leaving the pump is
called the effluent.
INLET A fitting in the pool or spa on the water
return line from the equipment that water returns to the
pool. Usually the last thing on the return line.
IONIZER A water-sanitation device that uses
electricity to generate metal ions, which are dispersed
in the water. It works by passing a low-voltage DC
current through a set of metallic (usually copper and
silver) electrodes placed in line with the circulation
equipment. The copper is an algaecide, while the silver
is a bactericide. Does not remove swimmer waste.
IRON Iron in water causes the water to be brown-
or green-colored. Can be controlled by the addition of a
sequestering agent or a chelating agent. Water can be
tested with an iron test kit.
ISOCYANURATES Also called stabilized chlorine - A
family of chlorine pool sanitizers that contain
conditioner (cyanuric acid or isocyanuris acid) to
protect the chlorine from the de- grading UV rays in
sunlight. The most common types are sodium dichlor and
trichlor. The granular form is dichlor, which is fast-
dissolving and can be used for regular chlorination or
super chlorination by broad- casing into the pool or
spa. Tablet or stick form is trichlot (which is usually
used in a chlorine feeder - either the floating type or
the in-line erosion type) used for regular chlorination
only.
