Frequently asked questions

Glossary of frequently used terms

ACID WASH: The process of cleaning the interior surface of the swimming pool to prepare it for being filled.

BACKWASH: Backwashing describes the process of pumping water through your pool's sand filter to clear it of debris. You should backwash your filter about once a month.

 

COPING: The material used to cap the pool shell wall and provide a finished edge between the pool and surrounds. Some popular options include concrete, tile, natural stone and timber decking.

CHLORINATOR: A salt chlorinator uses a chemical process called electrolysis to produce hypochlorous acid (HClO) and sodium hypochlorite (NaClO), which are the sanitizing agents that help to keep the swimming pool free from microbes and algae.

EXPOSED AGGREGATE: A blend of components including cement, quartz sand, metallic oxides, glass and pebble applied as a finishing surface to the interior of the pool. 

FILTRATION: The process of passing pool water through a filter medium, such as sand, to remove dirt and debris.

 

  • CARTRIDGE FILTER uses pleated polyester to capture dirt and debris. To clean a cartridge filter, squirt it with water from a garden hose.

  • SAND FILTER traps dirt and debris in silica sand. Backwashing (see above) is used to clean a sand filter.

FORMWORK: Built out of timber, plywood or sheet metal, the formwork is a temporary structure against which concrete can be sprayed and shaped. After the concrete has set, the formwork is removed.

HEAT PUMP:  An electrical device that transfers heat energy from the environment into the pool water to increase its temperature. This can prolong the swimming season and/or make swimming more comfortable. 

IN-FLOOR CLEANING: A system that removes dirt and debris from the pool by using a network of drains and retractable jets that circulate the pool water.

POOL CLEANER: A device or system designed to remove dirt and debris from the pool. Examples are: suction, pressure, robotic or in-floor automatic.

ROBOTIC POOL CLEANER: A unit that traverses the pool interior and removes direct and debris by sucking water through a cartridge filter. Most robots are also equipped with rollers to clean the tiled waterline.

WATERLINE TILES: A band of tiles set directly beneath the coping. As well as enhancing the appearance of the pool, they protect against waterline staining.

WET-EDGE: The waterline overlaps the pool coping to create a "wet edge". Water spills into a reservoir before being passed through the filtration system and back into the pool.
