  2. There are indicators on the side of the test strip container you should then use to check the levels are correct, the indicators for the correct balance are all coloured squares, in order for you to create the correct balance by adding chemicals you would be looking to match these colours on the test strip you dipped in the water to match the colours on the test strip container to set the water balance correct and safe to bathe in.

  5. After using your tub it’s a good idea to add one more teaspoon of Chlorine or Bromine to keep the levels correct for the next time you use it and also to help stop the water from turning stagnant.
  6. Alternatively, you can use an adjustable floater with Chlorine or Bromine tablets inside to help maintain correct water balance, just remember to take out the floater when the tub is in use.

Whilst testing, always have your tub fully functioning at least 20 degrees for best results.

Test the water the following day after it’s been used and add chemicals as appropriate, re-test the water after at least one hour after adding chemicals.

Best Way To Treat Cloudy Or Smelly Hot Tub Water:

Causes of cloudy smelly water are usually down to the level of water maintenance you provide to your hot tub, high levels of PH or low levels of sanitizer are usually the culprit, a build-up of scum is another reason,

How To Prevent Cloudly Foamy Hot Tub Water:

People often don’t realize that they “SHOULD” always shower before using a hot tub as things like make-up, fake tan, skin creams, and lotions will all end up in your hot tub water and stick to the side walls of your tub as well as end up in the plumbing pipes of your hot tub which all in all causes your hot tub water to go cloudy and smelly or cause hot tub foam.

It’s recommended to change the water completely when the tub has had a lot of use, you should notice the water will start to turn slightly cloudy and maybe a little bit smelly, these are signs that you either need to change your water completely by draining your hot tub Or by treating the existing water to save you the hassle of emptying it.

If you don’t wish to empty your tub then you could try to add a more than usual amount of bromine or chlorine with caution! By firstly mixing the sanitizer powder or tablets with water in a bucket before adding it to your existing water, this is going to reduce the risk of damaging the inner acrylic of your tub with such a large dose of chlorine or bromine added at once which should be done with caution!

Then add it to the existing water in your hot tub whilst testing for chlorine levels up to 10-ppm (parts per million) for best results, Then just leave it to soak with the hot tub cover ON for about an hour.

After that hour take your hot tub cover OFF and let it soak even longer whilst testing the levels of chlorine again, you might find the levels are way to high to bathe in so you MUST wait until the chlorine levels drop to the correct safe balance of at least 1 -3 PPM-(parts per million), Beware this could take days to settle down because of the sheer amount of chlorine initially added to treat the cloudy water.

If you decide to empty your tub, it’s recommended to give your tub a good clean with general household detergents and antibacterial products and give the tub a good rinse down with clean water before filling it back up with clean water where you would have to then repeat the above process to set your water balance correct again before you use it again.

Best Way To Treat Slimy Hot Tub Water:

Slimy water is usually a build up of biofilm microorganisms in your hot tub, biofilm builds up on the interior walls of your tub and in the plumbing pipes and jet systems, to spot biofilm you would usually see little white bits floating in your water and around the jet holes, this is known in the industry as hot tub plaque.

For best results is to completely empty your hot tub of all the slimy water, clean the inside of your tub and re-fill your tub with fresh water whilst treating the clean water with around a litre of biofilm flush cleaner and running your hot tub jets for a good hour or so to circulate the cleaning solution thoroughly, this will clean all the plumbing pipes inside your tub and the inside walls of your tub.

In this unfortunate event then it’s just your workload that is increased, As by recommended standards you should,

  1. Firstly completely empty your hot tub.
  2. Clean all the inside of your tub including jet holes and filters.
  3. Then fill it up with fresh water again.
  4. Add around one litre of biofilm flush cleaner to the new water.
  5. Then Switch the tub on with the jets turned on and run it for about an hour.
  6. Empty your tub again and re-fill with fresh water and add the usual chemicals to balance the water.
  7. Consider using a skin-friendly biofilm preventative that will also reduce the number of chemicals you will use going forward by nearly 80%, simply add two measures with the measuring cup provided once a week.
