Care & Maintenance
Once your spa is installed, the Maintenance section provides essential guidance on cleaning, regular checks, and other upkeep procedures to ensure long-term performance.
Cloudy Water
Cloudy water can be caused by one of 5 issues:
-
Action
- Check pH levels and adjust if necessary to between 7.2-7.6ppm.
- Check Alkalinity Levels and adjust if necessary to between 80-140ppm.
-
Action
- Remove your filter cartridges and clean with a filter cleaner from your pool/spa shop or Napisan works well.
-
Action
- Add a pipe/hose cleaner from your pool/spa shop to clean the interior pipe work.
- Run your tub for two hours, drain and flush spa, then thoroughly clean.
-
A line of brown scum can be caused either by excess body fats or when water contaminated with chlorine has been added to your tub.
Action
- Add a Chlorine Remover and run the pump on auto.
-
Foaming is usually caused by either incorrect water balance or an excess build up of body fats in the filter cartridge or pipe work.
Action
- Add some Anti-Foam to stop the foam from forming.
- Clean your filter cartridge.

"Hi Mike, FYI the spa arrived, and we have set it up and used it. Very impressed with the workmanship on the cedar! Also the size is perfect, exactly what we were after! We are very happy with the product, thank you!"

"This is the second tub we've bought from Mike so it's interesting to see all the changes and improvements. Everything is streamlined and simpler. The wiring up/ connection/ working parts are more straightforward and will be I suspect longer lasting."
Peter F (Auckland) ""This is the second tub we've bought from Mike so it's interesting to see all the changes and improvements. Everything is streamlined and simpler. The wiring up/ connection/ working parts are more straightforward and will be I suspect longer lasting...There are wee improvements everywhere, such as the rubber between the steps and the base and the double jets - 8 against the 4 in our earlier (medium sized) tub. The tub was lighter and so easier to maneuver into position. Also as the delivery is now done with a crane it's possible to get it plonked right where you need it I suspect for most people. The finish on the cedar around the rim and steps is less complex and WAY easier to keep clean - there are no cracks for leaves and debris to accumulate in. The new spa sanitizer is definitely a step up. It looks very well overall, and suits the vibe of our house SO well. We're just thrilled (and now have to stain our deck which looks rather tatty against it's elegance and beauty!)"Peter F (Auckland) See more Google Reviews
"We purchased a hot tub in March 2021 and had it transported from Napier to our house in Christchurch without any issues. It was straight forward to set it up and we had it operational within a few hours."
Hugh W (Christchurch) ""We purchased a hot tub in March 2021 and had it transported from Napier to our house in Christchurch without any issues. It was straight forward to set it up and we had it operational within a few hours...I positioned it in our garden and added decking, a cover over the filter / pump and some steps. With the ferns and lights looks impressive at night. About the only maintenance is changing the water and cleaning the filter 4 times a year (at the change of session). About once a year we apply some oil to the cedar. After 4 + years it still looks great. Over this time we have had almost flawless operation. The only issues I’ve had were a leaking light cover and a small leak due to a faulty O ring (this was actually my fault). Both issues I quickly fixed. Relax Hot Tubs have been quick to respond if I had any issues and always very helpful. I highly recommend them."Hugh W (Christchurch) See more Google Reviews
