Do you sometimes feel that your hot tub has developed a gritty tub scale? Do you often feel like sandpaper in your hot tub? Well, let you know that this is a very common issue with spa. Every hot tub users face this issue, so you are not the only one to worry about it.
Before this blog posts help you to fix your problem, lets us find out, what actually causes hot tub scale?
There are a few different elements relating to the tub water chemistry that is responsible for hot tub scale. Take a look at the factors responsible for hot tub scale:
PH level of hot tub water: The pH level should be maintained at 7.4 to 7.6. If you add warm water when the pH level is high, it can cause calcium to build up. The calcium gets settled on the surface of the tub.
Calcium hardness: Calcium hardness in the water is also responsible for hot tub scale. Often the calcium gets deposited while you fill the hot tub through a water source which is rich in calcium.
Alkalinity: The third factor which contributes to the hot tub scale is alkalinity of water chemistry. The alkalinity helps to control the pH levels. The alkalinity level should be maintained between 125 to 150 parts per million. You should know that high alkalinity results in high pH level which is responsible for hot tub scale.
Besides several other factors such as water with high iron, body lotions, body oils and many other contaminants in the water by bathers can also form scales in hot tub.
How do you fix the problem of hot tub scale?
For hot tub cleaning, you will have to follow a few steps. Do not worry, it is quite simple and will not consume much of your time.
To obtain the correct pH level and alkanity, you have to adjust the chemical you use for hot tub. The correct chemical level helps to loosen the scale and begin to disappear. As you know that the pH level should be between 7.4 to 7.6, therefore, by using a water test kit, check the water every 4 to 6 hours and adjust it accordingly.
You should even scrub the surface of the tub to remove the scale. If the scale is relatively new, it will simply get removed as you brush off, however, if the scale gets firmly deposited, you may have to take a spa scrubber brush to remove the scale as it gradually gets deposited on the surface. However, do not use any household cleaner which are not meant for hot tub, as these might scratch the surface of the rub or might cause water foaming or water chemistry issue.
Please note that you must refill the water as soon as you drain them. If you observe that there is a calcium hardness issue, then use spa filters at the time when you refill the hot tub. This helps to eradicate additional minerals from the water before it is used for hot tub. The filters should be cleaned regularly or else it will not be able to pick up the contaminants that are responsible for causing scums. You can clean the spa filter with your garden hose and soak it in any spa cleaner to clean it in the best possible manner. Moreover, as soon as you refill the hot tub, make sure that the chemicals used are balanced at the recommended level.
To prevent scale, add a stain or you can also use scale preventer. The scale preventer or spa pure stain will help in breaking down the minerals and hard water. You can also use scamball, which is a small floating ball to absorb body lotion or and body oil and even impurities brought into the tub by the users. Most importantly, continue with the dosage on a weekly basis to avoid the growth of hot tub scale.
Proper water chemistry is the key to a healthy and happy spa environment.
