Monitoring the water chemistry of your swimming pool is paramount for health and safety. We recommend monthly visits to monitor your dosing equipment.

Swimming Pool Bacteria Test

Keeping your pool safe for swimmers is achieved through regular testing. The top aspects tested for in a pool are:

  • Water pH
  • Chlorine
  • Alkalinity
  • Bacteria

This is along with your daily and weekly checks that are recommended for general pool upkeep. We would also recommend carrying out thorough tests following a prolonged period of closure, or when it is being used very regularly, for example in the summer months.

Guidance for the operation and management of swimming pools is covered by HSE guidance and Pool Water Treatment Advisory Group (PWTAG). Health and safety aside, keeping these levels within a safe zone prolongs the life of your pool and its supporting equipment like pumps and filters.

In professional swimming pool water testing, we can examine a wide range of chemical and microbiological parameters. We’ll check that your dosing levels are accurate, and in addition, we’ll sample the pool monthly for bacteria including E Coli, coliform and pseudomonas.

Dosing a Swimming Pool

Regular monitoring of the pool water chemistry and bacteria will ensure that your dosing levels are adapted to suit the environment. Manually dosing your pool is a hazardous activity and shouldn’t be performed by anyone who hasn’t received appropriate training.

Ideally, contaminants will be kept under control with regular testing and maintenance. However, shock dosing is sometimes required – we would advise this if bacteria levels are high. Shock dosing involves adding high levels of chemicals – such as chlorine – to your pool, and then bringing those levels back to safe limits before the pool goes back into use. It effectively kills any bacteria, algae or slime, improves water clarity and brings your swimming pool back to a stable state.
