How to Care for a Hot Tub?

How to set up a Hot Tub?


Setting up your hot tub is easy, a hot tub is a self contained unit and just requires a power supply, whether a standard 13 amp supply or dedicated hard wired supply. How you fill your hot tub is simple, there is no water connection to a hot tub. It can be filled using a normal garden hose and on average will take about 1 to 1.5 hours to fill and around 1200 litres of water.

Many people ask should you lower the temperature in a hot tub or keep it hot? What temperature you run your hot tub really come down to how you use your hot tub and how frequently its used. If used regularly its just as efficient to keep it at the desired temperature. If perhaps no used for periods of time, then it can be more cost effective to run the hot tub cooler. The important thing is not switch the hot tub off, this will lead to the water standing and potentially bacteria getting into the water. Leaving the hot tub on will allow filtration to occur.

Due to the excellent insulation of a Red Spa hot tub the temperature in a hot tub may rise from the summer heat. This is perfectly OK, its just residual heat from circulation pump, even though the heater is off, can lead to it going over the desired temperature. The hot tub will cope with this and go into standby until the temperature has dropped. Its also a good idea to run the hot tub cooler through the summer months.

How to Care for a Hot Tub?

All Red Spa hot tubs are fully automated, they will control water temperature and automatically filter the water as required. The duration of water filtration can also be set by the user according the hot tubs usage.

The main aspect of caring for a hot tub is looking after and maintaining your water. “Oh no – how do I do that? Is it complicated?” I hear you say! No its not! If you have been researching investing a hot tub, you might have seen words like “Total Alkalinity” and “Free Chlorine” being used. Don’t worry you don’t need to be a chemist or scientist to have a hot tub.

How to Sanitize a Hot Tub

There are 2 aspects to looking after your hot tub water. Firstly and most importantly its sanitizing the water – which simply put means keeping the hot tub topped up with a sanitizing chemical like Chlorine or Bromine. This will ensure your water stay free of anything harmful. Amounts are usually measured in PPM or “parts per million. What level should the hot tub chlorine level be? It should usually be around 3 to 5 ppm. Bromine however should be 4 to 6 ppm.

Balancing your water

Balancing your water involves adjusting the Ph of the water or the acid or alkalinity. You might remember pH from school days, its a scale which measures how acid or alkaline something is. Its important that your water is ‘balanced’ – If too acidic then the water is corrosive and can over time damage your hot tub, it also can be uncomfortable for the bather causing irritation to the nose or eyes. If to alkaline then you have a risk of scale forming in the tub which again isn’t good news for your hot tub. So balancing your water is important

Testing your Hot Tub water

Testing the water is as simple as a 15 second test. Using a simple test strip into the water, the pads on the test strip will change colour and you can compare the colours with a chart giving you the levels of the water. From this you can work out what you need to add to the water – if anything,

How to apply the chemicals to the water

In the majority of cases your water chemicals come supplied in granular form. Don’t apply directly to the water, but take a sample of the water from the hot tub (chemicals dissolver much quicker in warm water) then add the required dose to the water and dilute. You can then add this to the hot tub with the pumps running to ensure they are well mixed.
All our chemicals come with the dosage rates on the bottles making it easy and quick to adjust your water. So for example, how to chlorinate a hot tub – take a jug and fill with water, then add to the jug of water the required amount according to the bottle. Mix thoroughly to dissolve the granules then tip back into the hot tub. Run the jets for a while to mix the chlorine into the water. The tub will be fine to use in about 10 to 15 minutes. Its also a good idea to have the cover off whilst chlorinating the hot tub. This allows any gases given off to be well vented. Another common adjustment is how to lower the pH in a hot tub – this can be done in the same manner as the chlorine adjustment, by diluting the pH- in a jug of water and then reapplying it to the hot tub. If you pH is particularly high (or low for that matter) don’t be tempted to make large adjustments. Its better to tweak the pH over a course of days until the desired reading of 7.2 to 7.6 is reached.

Don’t forget, we’re always here if you get stuck too!

Clean that filter

An often over looked part of looking after your hot tub is keeping the filter clean. The filter is at the heart of your hot tub keeping your water free from debris and contaminants. Keeping you filter clean not only removes that contamination from your water is also reduces stress on your circulation pump.
