Swim For Life


Swim For Life (SFL) is an indoor learn to swim centre based on the Gold Coast. The 17m x 6m pool was originally built in 1966 as an outdoor pool that was enclosed & plumbed retrospectively. In April 2004, new owners purchased the centre and struggled through many issues such as poor ventilation, extreme condensation, uncomfortable pool temperature, declining client numbers and maintaining comfortable water for staff and pupils. Staff skin issues were extreme and retention of staff was adversely affected. Following renovations to the venue, conditions improved and bather numbers increased and it became more difficult to maintain healthy water. Various solutions were implemented and proved to be steps in the right direction but never completely solved the ongoing issues. At the end of 2013, SFL contacted Ozone1 and upon installation, a decade of problems disappeared.


During the installation the entire pool water was drained due to high TDS (Total Dissolved Solids) and fresh water was added. Four months post installation enduring heavy bather loads, the water quality is maintaining fantastic results, the clarity and odour has improved dramatically and Combined Chlorine has stabilized to 0.3ppm and below.

Secondary Disinfection: Ozone1’s Proprietary System Calculation was utilised along with our unique Advanced Oxidation Process (AOP) as a secondary disinfection system, which was suitable to combating SFL’s combined chloramines and in particular, the monochlorinamines issues.
Primary Disinfection: Ozone1’s Hydroguard -302 Blue I DPD1 & DPD3 controller was utilised to ensure consistent levels of Primary Sanitation (Free Chlorine & pH).

The Hydroguard Blue I controllers uses a colorimetric DPD method to determine the Free Chlorine & Total Chlorine measurements as opposed to relying on traditional ORP or Free Chlorine sensors. As a result, the outcome is extremely consistent sanitation (Chorine & pH) levels. The ‘Blue I‘ conducts a DPD1 & DPD3 test every ten minutes, and each and every test is uploaded via our “Remote Monitoring” to the Cloud and is stored for 2 years, which serves as valuable evidence to satisfy a possible complaint. The remote monitoring also allows SFL to access and view their water quality at all times and if set points aren’t met, alerts are sent to the appropriate personnel via text message or email.
