Spa Bacterial Growth

All spas have some bacteria. There’s no getting away from that, but sometimes bacterial growth in spas can become a problem. Because of the high water temperature and sometimes inconsistent sanitation in spas, bacteria have a very easy time growing quickly. Pretty soon, you have a bacterial infestation that can cause a myriad of problems that a regular shock application will not eliminate.

Sometimes this bacterial growth is evident in a slimy, white substance that looks like floating tissue paper. Other times, it might look like spaghetti filaments floating in the water. And other times, it may even result in the bathers getting a rash.

To eliminate bacterial growth:

  1. Drain the spa and refill just above the jets. Remove the filter and soak in a solution 25 grams of Chlorinated Concentrate to 10 – 20 litres of water for 12 hours.
  2. Add 50 grams of Chlorinated Concentrate per 1,000 litres. Turn on the jets and circulate for 2 – 3 hours. The bacterial growth usually builds up in the lines, so it is necessary to flush them thoroughly. Swirl Away may also be used.
  3. Drain the spa again and refill with fresh water. Rinse and replace the filter. Rebalance spa and shock.
