All your Hot Tub Chlorine Questions

As both products are chlorine based, they are essentially and when used correctly, as effective as each other at controlling the bacteria and sanitizing the water in your hot tub.

The key to achieving the perfect balance and level of control is to ensure your hot tub water maintains a chlorine level of 3-5ppm.

Chlorine tablets slowly dissolving in either a floating dispenser or feeder device ensure that you have a constant supply of chlorine entering your water. This method still needs to be monitored and the flow of the devices adjusted to maintain the perfect levels.

Chlorine granules added directly with their rapid dissolving properties support a more instant adjustment to the chemical levels in your hot tub water. However, if your hot tub is left unattended for a period of time, or you are unable to monitor and adjust the levels daily the chlorine demand of your water could be compromised.

The good news is whichever method of chlorine you use to stabilize the water in your hot tub, the costs are pretty similar.

If you opt for the SpaChem Spa Chlorine Granules, a 1kg tub will currently cost you from £16.92. If, however, you prefer to use the SpaChem Spa Chlorine 20g tablets, a 1kg tub will currently cost you from £14.83.

So luckily, on this occasion, price isn’t a huge influencer.

It goes without saying that care and attention must be taken when using all hot tub chemicals and this is the case for both chlorine tablets and chlorine granules.

Due to the way that they are manufactured, chlorine tablets are more acidic than chlorine granules. It is therefore important if you choose to use chlorine tablets that the floating dispenser is removed from your hot tub before you glide in.

The main risk with regards to chlorine tablets or chlorine granules not being used correctly is high elevated chlorine levels due to overuse and chlorine lock rendering the hot tub not useable. The second factor is correct pH & total alkalinity levels not being maintained at the right levels which will create an environment that will cause you tub to become too acidic or too alkaline, which will mean you burning through chlorine at a high rate.

Chlorine

Chlorine works by actively destroying any contaminants in the water of your hot tub. Whilst it breaks down the bacteria from the inside out, it dissolves in the water to form a waste product called chloramine.

By adding chlorine in your hot tub at least weekly, you will be able to keep chloramine at bay. You will know if you have a surplus of chloramine in your hot tub water as this is the chemical that has the notorious reputation for its unique smell, for causing stinging in the eyes and for drying the skin.

If the chlorine that you are adding as your hot tub sanitiser needs a helping hand, you can eliminate the number of chloramines in your water by doing a chlorine shock treatment. To help keep your water crystal-clear and ready to use, you will want to do this chlorine shock treatment regularly.  There are two types of shock which we will cover in our next blog, but calcium hypochlorite and an oxidizing shock call Non chlorine shock granules.

Its a very clear NO with regards to mixing the two sanitisers, when managing your hot tub water you need to use either or and not both together.  Bromine Granules and Bromine Tablets are fine to use together and similarly Chlorine Granules with Chlorine Tablets.  Please do not mix the two sanitizers.
