With all pools or hot tubs, one of the most important jobs is making sure that your water is regularly tested and safe to use. There are a number of parameters that can be measured including the disinfectant levels (usually chlorine or bromine), pH and alkalinity.
What is Alkalinity?
Alkalinity, normally referred to as total alkalinity, is the measurement of the alkaline salts (carbonat...
Chlorine is the most popular disinfectant used in swimming pools throughout the UK. The level of chlorine is dependent on your requirements and procedures laid down in your Pool Technical Operating Procedure (PTOP).
Once set, the chlorine level should be tested regularly and again, this should be specified in the PTOP but as a guideline, a minimum of three times a day would be recommended. ...
The last few months have shown us how important it is to control hygiene in all areas of life. This is also essential for swimming pool water. Although no one is certain how Covid-19 is affected by chlorine, it is generally thought that proving levels of free chlorine are sufficient and pH value is correct then the virus is rapidly inactivated.
Therefore, what does this mean with regard to wat...
Palintest provides an extensive array of options for testing pool water. In order to decide which testing system best suits your needs you first need to keep in mind the following:
Are you testing pool water for residential, home, or commercial use?
Are you testing single or multiple parameters?
How accurate do you need the results to be?
Below is an overview of where each type of...
Swimming pool water can sometimes appear cloudy. This is known as turbidity, and can be monitored and measured with a turbidity meter (aka turbidimeter).
We've taken a look at what causes cloudy pool water, how to monitor and measure it and how to correct and control it.

The Pool Water Treatment Advisory Group (PWTAG) is the independent UK authority o...
Higher range chlorine solutions are typically used for disinfecting products but standard chlorine meters often cannot measure to higher ranges. For example the Hach Pocket Colorimeter II for chlorine measures to a maximum of 2mg/L, and the MD100 Duo for Chlorine measures to a maximum of 8mg/L There are several instruments available for samples where chlorine levels are high, lets take a ...
Using Chlorine Bleach instead of expensive chlorine tablets can be a more cost effective solution when maintaining clean swimming pool water. Essentially the way to achieve this is to have the correct balance of pH and chlorine in the pool. The amount of bleach you need is directly related to the amount of water in the pool. Therefore use one half-gallon of bleach to every 10,...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
