How effective are chlorine tablets and chlorine granules?
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.
Are chlorine granules or chlorine tablets more cost effective?
The good news is whichever method of chlorine you use to stabilize the water in your hot tub, the costs are similar.
So luckily, on this occasion, price isn’t a huge influencer.
How safe are chlorine granules v’s chlorine tablets?
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.
