Hot tub troubleshooting: What to do if your hot tub feels slimy

Are you suffering with slime on your hot tub ? Here’s what to do if your hot tub feels slimy…

What causes hot tub slime?

Slime can be caused by a build-up of bacteria and microorganisms, known as biofilm. This can sometimes be seen and felt on your hot tub interior or can build up undetected in plumbing.

If you are suffering from cloudy water or water odour, you may have slime in your pipes.

Slime or biofilm occurs naturally but the hot tub environment (dark, warm and moist) can allow it to thrive. If the bacteria is allowed to build up it can be harmful to health and detrimental to your hot tub. Slime build up reduces the effectiveness of sanitizers and increases the acidity of the water.

If left untreated, it can grow, causing more problems and making it more difficult to remove.

How to get rid of slime

If you have slime in your hot tub, you can remove it by simply wiping it away. However, visible slime is probably only part of the problem, so you will also need to flush the pipes to ensure they are clear of bacteria.

To remove bacteria and slime from your hot tub plumbing, use Swirl Away before draining your hot tub and replacing the water. You should also clean the filter before refilling. If your filter is particularly slimy, it is better to replace it.

How to prevent hot tub slime

Minimise the risk of hot tub slime by doing the following:

  • Practice proper hot tub maintenance, and maintain correct water levels.
  • Flush your pipes with Swirl Away before draining your hot tub at least every three months.
  • Clean the filter regularly and replace filters every 12 months.
  • Shower before using the hot tub. This will reduce the amount of foreign bodies entering the hot tub that may help bacteria to grow.
