Modular, stackable filter units are described. The units may contain particles of glass or other filtration material and may be used to cleanse debris-laden water of, for example, swimming pools or spas. They additionally may replace conventional pleated mesh filters and beds of sand if necessary or desired.
Disclosed herein is a unit for a salt water pool chlorinator that is arranged for water to flow therethrough. The unit is configured for an electrode assembly to be received therein and is arranged such that some of the water flows through the electrode assembly. The unit has a channel, defined by a barrier impermeable to water, arranged for some other of the water to flow through the channel. At least one port may be arranged at the channel whereby at least one of a sensor, a feeder and an extractor can use the port to respectively detect, feed into and extract water in the channel.

A water treatment method for improving the water quality of a body of water is disclosed. A water treatment mineral is also disclosed, The water treatment mineral includes a third period electrolyte component comprising magnesium chloride and sodium chloride. The magnesium chloride is more than about 15% by weight of the third period electrolyte. The water treatment mineral may be used with existing water treatment equipment by adjusting the concentration to a level suited to the effective production of hypochlorite anions at a concentration sufficient to sanitize the water, The method includes adding the water treatment mineral to the body of water at a concentration of about 1200 ppm to about 9600 ppm. The water is passed through an electrolytic cell and an electrical potential is applied, sufficient to produce a predetermined concentration of hypochlorite anions in the mineralized water passing through the electrolytic cell to produce chlorinated water, The chlorinated water is then returned to the body of mineralized water.
+ from the potassium salt in an amount from about 40 000 ppm to about 120 000 ppm and hypohalite from the halide in an amount from about 100 000 ppm to about 400 000 ppm.

A water treatment product and a method of water treatment are disclosed. The water treatment product comprises a layer and a water treating agent. The layer comprises a substance sensitive to a parameter directly or indirectly indicative of water quality of a body of water to which the layer is exposed. The layer deteriorates when the parameter indicative of water quality is poor. The water treating agent is thereby exposed to the body of water when the layer deteriorates, thereby improving the water quality.
A method of sanitising swimming pool water including the steps of generating a region of increased water flow velocity at the electrolytic cell and employing a current density of at least 500 amps/m2 at said electrolytic cell.

A system for improving the water quality of a body of water, in which a parameter indicative of the water quality can be measured, is disclosed. The system may be implemented in the testing and subsequent improvement of the water quality of a swimming pool, pond, aquarium, spa, hot tub, or other body of water. The system comprises a comparator, against which the measured parameter is compared. The comparator is adapted to indicate a quantitative dosage of a water treating agent. The system also comprises a dosage format (i.e. a fixed amount of a repeating unit) that enables dispensing of the indicated quantitative dosage of the water treating agent. The dosage format may be a scoop, sachet, bag, pellet, tablet, bottle, container, bucket or other format that allows a discrete amount of water treating agent to be introduced to the body of water.

A comparator for use in improving the water quality of a body of water, such as a swimming pool, pond, aquarium, spa, hot tub, or other body of water, is disclosed. The comparator is adapted for comparing one or more results, whereby the or each result corresponds to a measured parameter indicative of water quality. The comparator may be further adapted to indicate a quantitative dosage of a water treating agent required to improve the quality of the water, responsive to one or more of the measured parameter(s). The comparator comprises at least one movable portion which, when moved to the result of the parameter measured, indicates the quantitative dosage of water treating agent to be used. The quantitative dosage may be indicated in a number of ways, such as by weight or volume, or by some other form of discrete measurement (such as a bag, bottle, sachet, tablet, etc).
