CLEANER WATER
Reassurance with quality water testing
If you want to be reassured that you have safe bacteria free water for your family to swim in – you must test the pool water – and test it regularly. The key routine tests are the disinfectant levels (normally chlorine or
bromine), pH, total alkalinity and calcium hardness – but why are these all so important? Chlorine and bromine – maintaining these levels ensures sufficient free or active disinfectant to guarantee adequate ‘killing’. Low levels may result in bacteria surviving in the water and infections occurring. Especially after or during heavy usage, disinfectant levels become quickly exhausted. pH – this measures the acid or alkaline level of the pool which, if
extreme, can cause irritation to the swimmer. The effectiveness of chlorine and bromine is also pH dependent. It is recommended that pH levels are kept between 7.2 – 7.6. Total alkalinity – (not to be confused with pH) is the measurement of the alkaline dissolved salts and this acts a buffer in the water. Low alkalinity can result in “pH bounce” - swings in pH occurring every time chemicals are added. High alkalinity makes the water highly buffered and complicates the pH control. Calcium hardness – affects the pool’s condition. When too high, calcium deposits form, giving a ‘matt’ appearance to surfaces such as tiles and pool surround. When too low, the water looks for calcium, potentially removing calcium content from other materials eg concrete and grout. Lovibond® Tintometer® has been a leading supplier of pool water testing equipment for over 50 years. The company offers a wide range of testing equipment to meet every application and pocket. The range includes simple block testers through to photometer-based digital systems.

Pool covers – handling safety and heat retention
If you have a swimming pool – you need a pool cover. Safety issues are important but its environmental issues and saving costs which are the key issues as a properly fitted cover will offer speedy heat retention. Whether it’s for safety, convenience, aesthetics or energy savings – or a combination of all four – the fact is automatic pool covers in particular are proving more popular every year. Less water evaporates from a pool with a cover, especially an automatic one that can be easily unfurled. A pool with a cover is also easier to keep chemically balanced and warm. So while safety concerns are naturally important to consumers, so is saving energy in today’s greener climate.
