Total Aerobic Colony Counts, commonly abbreviated using the acronym TACC, is one of the most misunderstood aspects of water quality analysis and microbiological testing. Partly it’s because microbiologists and water management professionals are so accustomed to using jargon that it becomes second nature, and they don’t realise that the terms they are using baffles and confuses the layman. Then when they’re asked to explain Total Aerobic Colony Counts in words of one syllable, they get all tied up in complicated scientific knots, and are unable to articulate simply what they are talking about.
In this expert guide the pool specialists at Water Treatment Services take a brief look at swimming pool water treatment techniques including how to maintain pool water balance, the importance of biocides, controlling algae and the role of filtration.

Unlike other water systems found in homes and commercial premises where the water is flushed or drained away after each use, swimming pools, hot tubs and spas could be considered as a re-circulating water system where the water is retained and re-used many times over.
If you’re not testing the chemical and microbial water quality regularly, taking steps to maintain balance and keep it clean, issues such as pH and water clarity can change, and more worryingly bacteria can start to grow rapidly.
Bacteria such as E. coli, Pseudomonas aeruginosa and Legionella thrive in warm, poorly or untreated water and have the potential to make people using the pool or spa very ill.
Don’t assume that water which appears crystal clear is clean and safe to use – the types of bacteria which can grow in water are invisible to the naked eye.
UK health and safety laws dealing with swimming pool and spa water quality, testing and treatment really only come into play if you’re running a business such as a leisure centre, gym or hotel, or the pool is in a holiday property which is let to paying guests.
Owners and operators of pools and spas need to ensure sure that the water quality and treatment programmes are effective and meet current standards.
Although the law might not apply to domestic pools and spas, they provide excellent guidelines and standards which it makes sense to read, understand and comply with.
For more information both the Health and Safety Executive and the Pool Water Treatment Advisory Group (PWTAG) provide excellent guidance to help pool operators comply with health and safety law.
It is very important that regular microbial analysis is carried out to ensure the effectiveness of the water treatment programme is maintained and the pool is safe to use.
Specialist microbial analysis is carried out in the laboratory, not in-field.
Swimming pools operated as part of a business should be tested on a monthly basis.
Microbial testing of privately operated pools is at the owner’s discretion, however we recommend the same testing frequency.
Our swimming pool microbial laboratory testing suite includes for the following:
Frequency – These tests should be carried out on a monthly basis.
Hot tubs and spa pools typically contain lower volumes of water and operate at higher temperatures than swimming pools.
These factors can increase the potential for bacterial growth in the water, including the risks from Legionella bacteria and other waterborne pathogens.
Our hot tub and spa pool microbial testing suite includes for the following:
Frequency – These tests should be carried out on a monthly basis, or when the spa is first used or recommissioned, after a report of ill-health, if there are problems of contamination, or if there have been alterations in the treatment/maintenance programmes.
If there are reports of ill-health from bathers further testing may also be required for other organisms including Staphylococcus aureus, Cryptosporidium, Giardia and possibly viruses.
In addition to routine microbial analysis of pool waters regular chemical testing should also be carried out.
One of the most important chemical parameters you’ll need to keep under control in your swimming pool or spa is the pH of the water, often referred to as the “balance”.
This is a way of determining how acidic or alkaline the water is.
Adding pool chemicals to the water can often change the pH levels and may prevent other chemicals from working as well as intended.
pH is measured on a scale of 0 to 14. 0 is an extremely strong acid, 14 is strongly alkaline, and at the mid-point, 7, the water is neutral.
Experts agree that the ideal pH range for water in swimming pools or hot tubs is between 7.2 and 7.6.
This is a range which is comfortable for skin and eyes, allows chlorine added to the water to work properly, and within this range water scale problems are unlikely.
If the water pH starts to fall too low into the “acidic” range, you may find that the water becomes irritating to skin or eyes, pool equipment including heater elements start to corrode.
You may also start to notice a build-up of minerals around the edges of the pool itself.
On the other hand, if the water becomes too alkaline, you might notice skin irritation, but also water clarity reduces and scale starts to form on the sides of the spa or pool.
In the UK, mains water from the tap will have different pH levels depending on where you are in the country, how your water is treated and local geology – what type of rocks the water flows through on its way to your local reservoir.
It’s therefore impossible to set-out a standard water treatment regime which works for everyone, as the water in tubs will tend to be different from the start.
Measuring levels of chlorine or your biocide of choice in pool water is also important.
Chlorine is currently the most popular biocide for the control of bacteria in pools but needs to be maintained at optimum levels – enough to kill any bacteria in the water, but not too much to cause health issues for bathers or accelerated corrosion of the equipment and other components used in the pool or spa.
There are various ways of testing the essential chemical parameters in your pool water including pH and chlorine (usually free or total chlorine).
Electronic meters are also available that will measure pH and chlorine levels. These are simple to use but more costly than test strips and tablet methods.
Please remember that there is no “best” way of testing the chemical parameters of your water; the key is to understand why you should be testing, how to do it correctly, and to do it regularly.

On the other hand, if the water becomes too alkaline, you might notice skin irritation, but also water clarity reduces and scale starts to form on the sides of the spa or pool.
In the UK, mains water from the tap will have different pH levels depending on where you are in the country, how your water is treated and local geology – what type of rocks the water flows through on its way to your local reservoir.
It’s therefore impossible to set-out a standard water treatment regime which works for everyone, as the water in tubs will tend to be different from the start.
Measuring levels of chlorine or your biocide of choice in pool water is also important.
Chlorine is currently the most popular biocide for the control of bacteria in pools but needs to be maintained at optimum levels – enough to kill any bacteria in the water, but not too much to cause health issues for bathers or accelerated corrosion of the equipment and other components used in the pool or spa.
There are various ways of testing the essential chemical parameters in your pool water including pH and chlorine (usually free or total chlorine).
Electronic meters are also available that will measure pH and chlorine levels. These are simple to use but more costly than test strips and tablet methods.
Please remember that there is no “best” way of testing the chemical parameters of your water; the key is to understand why you should be testing, how to do it correctly, and to do it regularly.
