Hot Tub & Spa Chlorine Guide

Sanitise your spa water

The reason that sanitisers are used in spas is to ensure that the water is healthy by preventing and killing bacteria. This is achieved by continuously and consistently maintaining a level of sanitiser (disinfectant) in the water with either chlorine or bromine. For expert advice, please contact Penguin Hot Tubs directly on 0800 112 3886 or via email: office@penguinspas.com where we will be more than happy to assist.

Chlorine

Chlorine is a commonly used chemical to achieve satisfactory bacteriological and chemical purity in spas. It must be present in the ‘free’ form to kill bacteria and oxidise organic matter derived from bathers. Provided the water is balanced (see chemical guide), chlorine levels of between 3.0 to 5.0mg/l are sufficient to maintain healthy, clean water. A well managed chlorine treated spa will have no odour and levels of chloramines (combined chlorine) of less than 0.5mg/l.


Combined chlorine is created as a result of a reaction between free chlorine and organic matter and is a mixture of Monochloramine, Dichloramine and Nitrogen Trichloride. The latter is mostly produced when the water is not being treated adequately and gives rise to the ‘chlorine’ odour.


Penguin Hot Tubs would recommend using AquaSPArkle as it has proven to make it easy for you to maintain your sanitiser level by giving you a choice of products to suit your spa situation, preferred dosing method and budget - visit our online store.


AquaSPArkle Spa Stabilised Chlorine Granules

A traditional, granular chlorine donor that is popular with many spa owners as it gives dose rate flexibility. These granules are rapid dissolving making predissolving and application easy. The granules have a pH value of about 6.0 – 7.0, which is fairly close to the ideal spa water pH level and so will have little effect on the pH level of your spa water.


AquaSPArkle Spa Multifunctional 20g Chlorine Tablets

AquaSPArkle Multifunctional Chlorine Tablets should be dosed via a floating dispenser. When set up correctly your floating dispenser will dispense the correct amount of chlorine into the spa to maintain the ideal level between 3.0 to 5.0mg/l and all you need to do is top up the floating dispenser with new tablets as and when required. This makes maintaining the sanitiser level in your spa very straightforward. When using a floating dispenser remember to remove it from the spa and place it on a non-bleachable surface while people are bathing. Please note Spa Multifunctional Chlorine Tablets are designed to maintain chlorine levels (as they are slow dissolving), so before using them the correct chlorine level should be established using AquaSPArkle Spa Stabilised Chlorine Granules.
