Spa Bacterial Controls & Applications
Maintaining a clean and hygienic environment for your customers is vital to guarantee their comfort. Comfortable customers = happy customers and are inevitably the ones who come back to you again and again. Traditionally, keeping pool and spa water clean has been a laborious task requiring numerous chemicals and extended periods of downtime. So, how beneficial would it be for your business to be able to manage biofilm build-up, TVC's, and Pseudomonas in as little as 10 minutes? Today, we explore Chlorine Dioxide T25 and why it could be the perfect solution for you.
What is Chlorine Dioxide T25
Chlorine Dioxide is a chemical compound that has commonly been used for a wide variety of antimicrobial purposes. Alongside the disinfection of drinking water and to sterilize medical equipment, it is also highly effective at maintaining pool water in spas, gyms, and swimming environments. At SpaChem, our Chlorine Dioxide T25 tablets help to speed up your maintenance process. It has been shown to effectively fight against specific pathogens such as legionella bacteria.
How does Chlorine Dioxide T25 work?
Upon contact with water, these tablets produce a concentrated solution of chlorine dioxide. When this solution reaches the internal pipework of your pool or jacuzzi, it effectively removes pathogens such as biofilms, organic sludge, and other containments.

The primary fact in which scale starts to build up is due to calcium hardness in your water, this due to your water balancing going out of balance. It really is imperative when looking after your tub that you start with keeping a keen eye on your pH levels and your Total Alkalinity levels which are the framework to managing water effectively.
When your water pH goes out of balance you will find that scale/calcium will start forming on your hot tub surfaces, seat wells, and in your pipework and jets.
Spa Water Management
Answer: Over the next few weeks the
SpaChem team will be discussing and supporting hot tub owners with
troubleshooting guides with what to do when you lift off the cover and find
that the water is far from crystal clear. It doesn’t matter which make, model
or size of hot tub you own; the general rule of water
management is the same for all.
Starting with one of the more common
What’s causing it?
Green hot tub water is commonly caused by a simple, non-flowering aquatic plant. Ok, that’s just a nicer way of saying that its highly probable that you have algae in your water after all, algae love to grow under the cover of your hot tub in the dark yet warm water environment.
One of the simplest methods to test if it is algae causing this problem, is to touch the inside of your hot tub walls, if it feels slightly slimy to the touch, then the chances are its algae. The likelihood is that this has happened due to either insufficient sanitizer levels (Chlorine or Bromine) in your hot tub or your filter is not performing at its best.
How to solve it.
Test the pH and alkalinity of your hot tub water and try a Hot Tub Shock / Non-Chlorine Oxy Shock. After filtering out the dead algae we would recommend that you look to clean your filter to remove any loitering algae. For more information on the products available and how to conduct a shock treatment, visit https://spachem.co.uk/hot-tub-shock
If the above has not rectified the problem and 24 hours later, your water is far from crystal clear, then it’s time to drain your water, thoroughly wipe all of the internal surfaces of your hot tub (to remove any remaining algae), replace your filter and refill with freshwater, not forgetting to balance your waters Total Alkalinity, then pH which will ensure you are giving your sanitizer the best water environment to work at its best.
There are other causes of green water such as the presence of minerals (copper, manganese, and iron is the main culprits) from the pipes that fill your hot tub, or even present in your household water and don’t forget the no-go rules around fake tan. The chemicals in your hot tub will react with the fake tan and result in some interesting shades of brown and green on the sides of your hot tub and in the water!
Spa pH Balancing & Control
Recommendations for addressing high levels of pH and alkalinity.
When it comes to balancing the pH and alkalinity of your hot tub water, they follow the same principles; if your levels are low, use a plus increaser and a Total Alkalinity Increaser, always remember the rule of thumb and balance your Total Alkalinity first, then your pH, if your levels are too high, use a pH & Alkalinity Reducer or Minus product!
If your alkalinity is too high, we would recommend that you… use a combined pH & Alkalinity Reducer as typically if your water is either high in pH or naturally high pH from the source then your Alkalinity normally follows suit.
If your pH is too high, we would recommend that you…. use a combined pH & Alkalinity Reducer as typically if your water is either high in Alkalinity or naturally high TA from the source then your pH normally follows suit.
To ensure that you get the right hot tub chemistry, remember the rule of thumb, and always balance your alkalinity before you address any issues with your pH readings.
The water Alkalinity or Total Alkalinity (TA) of your hot tub is a measurement of how your water is able to neutralize acids and as such is a key component to the balancing of your pH levels. The alkalinity levels act as a buffer to help your water resist drastic changes. If the alkalinity of your water is unbalanced, it can cause the pH readings to be either too high or too low. The alkalinity of your hot tub should be between 80 to 120ppm.
pH on the other hand is a measurement of how acidic or alkaline your water is. The ideal range for pH in your hot tub water is between 7.2 and 7.8, as this will allow the chlorine in your water to work more effectively at keeping your water clean. We would recommend that you check the pH level of your water a minimum of twice a week as sanitizers and minerals in the water can have an impact on your reading.
Spa Sanitization Bromine
Are you finding as time goes on your spa smells? Looking forward to a nice relaxing soak in your hot tub but when you open up your spa cover you get this unpleasant odor? But the temptation of getting into what looks like a nice clean hot tub may have underlying issues.
A hot tub that smells like rotten eggs is a sure sign that bacteria is hiding somewhere in your spa, spa parts, Jets, headrests, and spa cover, maintaining poor levels or low levels of bromine in your spa hot tub will result in high bacteria growth. To ensure a consistent presence and dosing of bromine in your water it is recommended using a tablet dispenser for Bromine Tablets.
So for some, this is a preferable sanitizer. However, as with any chemical sanitation system, bromine has its disadvantages. In small quantities dissolved into hot tub water, bromine is not too harmful, but it is naturally irritant to the human eyes and throat, so it’s best to avoid these areas and make sure you don’t swallow any hot tub water!
Bromine on the other hand works by forcing apart the chemical bonds of the contaminants in your hot tub water and as it dissolves in the water it remains active, continuing to work even when it has combined with the unwanted particles.
Unsurprisingly (and like its cousin chlorine), bromine also produces a waste product which is known as bromamine. However, bromamine is not known to have as many side effects when present in your hot tub, but it will reduce the efficiency of your bromine sanitiser. If you are using bromine in your hot tub as your sanitiser of choice, you will want to test the chemical levels regularly and undertake an oxy-shock treatment if the levels need adjusting.
Spa Sanitization Chlorine
The good news is whichever method of chlorine you use to stabilize the water in your hot tub, the costs are pretty similar.
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 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.
