Product Description

Removes Biofilm & pathogens from all surfaces & hard to reach areas of pipework and within spas and whirlpool baths.
Quick & easy to use, 100 times more effective in removal of biofilm than Chlorine - Cleans and disinfects.

How does it work?
Each tablet generates Chlorine dioxide which is a soluble gas with the advantage that it penetrates through the biofilm and removes it. Chlorine can't do that because chlorine must oxidize through the biofilm first. Pure-Spa Power tab is about 100 times more effective in the removal of biofilm than chlorine.  Biofilm is a habitat for dangerous pathogens such as Legionella, other bacteria and viruses. Without biofilm, chlorine consumption and the production of harmful disinfection by-products like trichloramine - responsible for the pungent chlorine smell in the air - will decrease.

Please Note: The packet may be supplied unbranded.

 How to use

Usage guide: 1 x 20g tablet for a Spa or Hot Tub

Apply 1 tablet per 500 - 1,999 litres of spa water prior to draining (domestic).

Warm hot tub water can provide the ideal breeding ground for bacterial growth. As this begins to attach to spa pipework and surfaces, biofilm can begin to form. Biofilm is extremely resistant against chlorine and can harbour bacteria and other pathogens. Biofilm Eliminator Tablets are a highly effective cleansing agent that penetrates the biofilm and helps remove bacteria.

Application Instructions

1. Remove and thoroughly clean cartridge filters before returning to service.

2. Ensure free chlorine or total bromine levels are within the recommended range of 3 - 5mg/l (ppm).

3. Only use Biofilm Eliminator tablets prior to draining down your hot tub.

4. Caution: Do not use hot tub during treatment.

5. Remove any soft head rests that may be fitted.

6. Isolate any chlorine or bromine feeder prior to Biofilm treatment.

7. Refer to the below table for the correct dosage requirements.

8. Wear protective gloves and eye protection when handling the product.

9. DO NOT touch tablets or allow them to get wet prior to adding to the hot tub water.

10. Use scissors to cut open the sachet(s) and carefully drop the required number of tablets around the pool or spa perimeter with the pump(s) running.

11. Leave the deep clean treatment for 60 minutes with the pump(s) running.  After treatment, turn the pump(s) off and drain all the water to waste.

12. Refill with fresh water and return hot tub water to recommended chemical levels.

Each sachet contains 1 x 20g tablet.

 Frequently asked questions:

 What is Chlorine Dioxide?
Chlorine dioxide may sound a lot like chlorine, but it is an altogether different chemical compound with the formula ClO2. Municipal authorities started using it to disinfect drinking water as early as 60 years ago. It is still widely used for this purpose today. And with good reason: chlorine dioxide is less corrosive than chlorine and superior for the control of legionella bacteria. It is more effective as a disinfectant than chlorine in most circumstances against water borne pathogenic microbes such as viruses, bacteria and protozoa. Chlorine dioxide is also used as a disinfectant of medical equipment and for odour control. When used in spas, it is not only disinfecting the water, but also breaks down the biofilm that may form in the tubing system and which can act as a growing ground for micro-organisms. The particles that result from disintegrating the biofilm is filtered out by the spa filter system.

Is it a problem when traces of other disinfection products are still in the spa water?
No,as far as is known, the Pure-Spa Power Tab can be used even when traces of other disinfection product are in the water. 

 A lot of filth appeared in my spa? How can that happen? It is clear that the Pure-Spa Power Tab did the job. The filth has come out of the tubing of the spa since the product obviously detached the biofilm. The pipes and tubes contained dirt which has come off now, into the spa. The filter will catch these contaminants.
You should completely drain the spa water, rinse and refill with fresh water. If necessary replace your filters too.

Can Pure-Spa Power Tab be used in combination with the ozonator and the UV-lamp of the spa? Yes, Pure-Spa Power Tab can be used with ozone and UV without any problem. The UV will however reduce the effectiveness of Pure-Spa Power Tab..

How fast is the Pure-Spa power tab at disinfecting water?
Within a couple of minutes all bacteria are killed. Chlorine takes much longer to be effective.

 What is the shelf life of Pure-Spa Power Tab?
The products is guaranteed effective for 2 years.

Really great product, first time Iíve used it but impressed with results. Will definitely purchase again.


Having used another companies product since our spa bath was installed, I was surprised to notice a build up of black bits, after our bath wasnít used for 2 months, due to being away. I continued to use the product we had used before, but it just wasnít tackling the problem. I researched the Internet and found this Biofilm Eliminator Tab, and boy did it do the trick, the slime that came out of the pipes was amazing. We have since gone over fully to Pure-Spar products, and as of yet, the black bits havenít come back.

This was the first time that I had used one of these 10g tablets on my whirlpool bath. I was amazed by just how much of this bio-film appeared during the cleaning process. I will be using one of these every six months from now on, in addition to the usua, after each bath, tablet I use.

Used these before easy to use will continue to use

I am using these for a whirlpool. I am very happy with the result. They seem to do the job very well.

Reviewed by Susie

I have used these tablets since they first came onto the market after having used the Spa100 which is in liquid form and basically the same compound but in tablet form. I found they are easy to use, just pop them in and presto after around an hour it is ready to use. Hydrospares sell them at a reasonable price and that is the reason why I have purchased them on two occasions and will continue to buy from again.

Questions & Answers

Can you advise if this product and the cleanser/degreaser are both suitable for my air bath? We have a phantom whirlpool bath as advertised on the better bathrooms website. If not can you please recommend what we should use? Thank you.

Asked by Jackie Derrett
Yes, it would be fine. Just be sure to really well ventilate with this product as you have an air system. It\'s really good for older systems that need a good clean. If you have a new system i would advise the Pure-Spa whirlpool sanitising tablets after each bath and the Pure-Spa whirlpool cleaner (make sure air is off and don\'t leave unattended as it will foam)
Response from Rosie

should it be used with hot or cold water?

Asked by carol
Hello, thanks for your question. Its fine to use with either warm or cold water.
Response from Rosie

Do you leave the whirlpool running whilst this tablet is in the water, or do an occasional on/off?

Asked by ZG
Its most effective if the water is circulating through the pipes, but it will still work at oxidising the contaminents in the system if you were to run the jets for a while then turn them on & off occassionally.
Response from Rosie

Is this only one tablet in package How does it work? Is £4. 99 price less discount? Thanks
