In order to service the Australasian Market we have recently launched exactMICRO.com.

Pool Bits has Imported and Distributed the Exact Micro and the Exact Ez Series of Water Quality Testing Photometers and Reagents for the past 5 years.

Introducing the Exact Micro 7+ Range to the market in 2009 has been a huge success and it hasn't taken long to be a dominant player in the Water Quality Testing Arena.

The exact Micro 7+ is a accurate, easy to use affordable meter, and as far as reliability is concerned ITS has backed their latest upgraded models with a 5 year manufacturers warranty, the only catch is... is that you must make sure you have Registered your new meter. Check out the Instruction Manual for all the necessary information.

Water Quality Update by Brett Alexander - www.poolbits.com.au

Councils around NSW are starting to enforce stricter guidelines when it comes to testing recreational water as set down by the NSW department of Heath.

There’s a dilemma on the horizon for NSW Motel, Hotel, Gym, Swimming School and Hydrotherapy owners regarding stricter guidelines for public recreational swimming Pools and Spas, most NSW Councils are imposing mandatory Water Quality Testing as outlined below.

Don’t think for a second that this dilemma is an isolated NSW case, our Federal Government is also aiming to have the entire National Pool Industry bound by the one uniformed Licensing Code by the end of the year 2009.

An example of these conditions are set out below, I’ve outlined the most common tests using extracts from the NSW Health guidelines for recreational swimming Pools and Spas, for individual requirements visit www.health.nsw.gov.au the guideline is very informative dealing with every aspect of running a public Swimming Pool or Spa.

Suitable testing apparatus shall be used to ensure accurate results. Fresh reagents tablets sealed in foil, Strip’s and Drop’s stored in accordance with manufacturers specifications should be purchased just prior to the swimming season or at least once a year.

The test methodology specified by the manufacturer of the testing apparatus should be strictly followed. Liquid testing reagents must be stored in sealed containers.

NB: Test kits using ortho-tolidine as a reagent to determine chlorine or bromine have been withdrawn from sale because of the carcinogenic properties of the reagent.

NB: Plastic, Perspex Kit’s or Test Strips known as "4 in 1" or "5 in 1” are not suitable for testing public swimming and spa pools.

The following test methods are considered suitable using Digital Photometric or Colorimetric methods using DPD reagents then recorded on appropriate logging stationary.

Chlorine/Total Chlorine/ Bromine/ pH/Polyhexamethylene biguanide ("baquacil® oxidizor") is a disinfectant and a preservative used for disinfection on skin and in cleaning solutions and used in Spas. (for more information go to taxidermy.net) will be measured at opening then once every 2 hours during daily operation.

Total Alkalinity / Ozone (Note: This testing method is still under development as chlorine and bromine may interfere with the result but now can be tested efficiently with an Exact Micro 7+ photometer.) According to Australian Standards considerable reduction in levels of chlorine may be applied when using this method of sanitization. All once a Day.

Cyanuric Acid/Total Dissolved Solids/Turbidity/Bacteriological Sampling (First 2 months). All once a Week

Bacteriological Sampling (Second 2 months) once a Month.

The most important line of defence to prevent the spread of recreational water illness and to protect any facility from the damaging effects of contaminated water is to maintain proper water chemistry.

As mentioned all above methods of testing evolve around the use of Digital Photometric or Colorimetric methods if you need advice or consultation on further developments, types of testing apparatus, treating or designing a test program please contact me. brett@poolbits.com.au
