    Teaspoon Chemistry

    A Teaspoon of chemical can compensate up to 1500Lof water.

    Don’t let the volume of water overwhelm you into thinking you need to put the whole bottle of granules in the tub for it to make a difference.

    It’s better to add little at a time and build it up until you get the right reading, instead of putting too much in to begin with and risk having to drain your tub and starting again. Once you’ve put too many chemicals in, you can’t reduce it without diluting your water, which is hassle you don’t need.

    First Things First…


    Your filtration cycle is SO important when keeping your tub happy and running smoothly. The first thing you should do to your tub, is set the filtration. Wizard recommend your filtration to be on F2. To change the filtration setting…

    Press: [Cool Jets] – use the arrows to go through the settings, once on F2, Press [Jets] to set.

    Poor filtration can affect your pipework, pump, heater and general state of your water.



    When testing your water, you’re looking for: Total Alkalinity (TA), PH and Chlorine. Also, when testing your water, dip a test strip horizontally, about 12 inches/30cm under the water level, follow the instructions on the test strip bottle and compare the colour of the test strip to the colour chart on the test strip bottle.


    The first level to get right is your TA, this is a base to build up the rest of your chemicals from. Once you’ve got your TA right, everything else is a breeze. If your TA is low, this means bacteria can live in your water and the water can become corrosive. If your TA is high, you may experience scale forming in your water do to unclean pipework. Also, if your TA is high, you can use PH Minus to bring it down. Using PH Minus may effect your PH but then adding small amounts of PH Plus can then raise your PH levels, not affecting your TA levels.


    Next up is your PH. Once you’ve got your TA right, your PH shouldn’t be far off. Your PH levels should be between 7.2–7.6. I know what you’re thinking, there’s not much difference between that, however it can make a big difference. In science terms, the PH scale goes up logarithmically, which means there’s a big difference between 1 and 2 or 8 and 9. So the PH must be in between 7.2-7.6 for your water to be happy and healthy.

    High PH? Use PH Minus

    Low PH? Use PH Plus


    Chlorine can be added by sprinkling the granules over the surface of the water. It’s recommended that you add the chlorine in small amounts to begin with to prevent overdosing. Leave the water for a couple of hours before retesting. Depending on the state the water is in, the Chlorine may have been used up, therefore you’ll have to add more. When the water is clean and properly balanced, some Chlorine residual will remain in the water. Leave your hot tub lid off for an hour after putting chemicals in, giving the evaporating water somewhere to escape. Keep the chlorine level between 3-5 on your test strip.



    Your filters are working so hard to keep your tub clean, so the least we can do is give them a little TLC every now and then.

    • You should be hosing down your filters weekly, you’ll be surprised what comes off your filters just from a quick hose down.
    • Your filters need a cleaner on them every 3 weeks. The best thing we’d recommend is our ‘Instant Filter Cleaner’. Simply spray your filter with the cleaner, leave on the filter for an hour before rinsing it off. Rinse until you see no bubbles or blue soap from the cleaner in the filter.
    • Your filters need a deep clean every 3 months. For a deep clean, we’d recommend using a Cartridge Cleaner. Fill a bucket of water with the cartridge cleaner in the water, place the filter in the bucket and leave overnight. The next day rinse down the filter, keep rinsing until all the bubbles and soap are gone from the filter.


    Leaving your filters to dry is a MUST. It lets the fibres in the filter tighten back up, making your filter more efficient at its job. It also expands the life of your filter.

    If you have more than one Hot Tub, NEVER swap the filters from one tub to the other. Bacteria can live in your filters and create problems for your water, pipes and heater. However, cross contaminating filters with another tub, you could be creating the same problems for another tub, which is just an expensive hassle that can easily be avoided.


    Water Hardness…

    Depending on where abouts in the country you live, you’ll either have; hard water, soft water or medium water.

    Hard Water:

    If you have hard water, this will take a toll on your pipework. Creating scale, which will float around in your water and your pipes will soon clog and/or corrode. Your pump will have to work twice as hard to get water through the pipes, which puts pressure on your heater. To prevent this from happening, use ‘ScaleAway’ weekly in your tub. This will flush away any scale build up in your pipes and will soften your water.

    Another product you could use is our ‘Hot Tub Conditioner’. This is another great way to make your water feel soft and it coats your pipes in a conditioner, making them silky and easy for your water to pass through. Silky pipes make it nearly impossible for scale to form. As they say, prevention is better than cure.

    Medium Water:

    Medium water is simple. Hard and Soft water has its disadvantages, but medium is unproblematic and won’t cause you much hassle if maintained properly. Just keep on top of your essential chemicals (TA, PH, Chlorine, etc) and you should be fine.

    Soft Water:

    Soft water isn’t as problematic, however we recommend putting ‘Hardness Increaser’ in your tub once a week, if your water is soft.


    Shocking Your Water…

    Shock Treatments take care of things that your chlorine and filters can’t, like stubborn bacteria, bodily oils, drink spillages in the tub and detergent from your swimwear.

    For a quick fix after a heavy use of your tub, we would recommend using our ‘Oxidiser sachet’. Tip the whole 35g sachet into your tub and this will give your water a good clean without you having to drain your tub.

    If you’re planning on getting in but don’t think it’s been cleaned for a while, you can put in a teaspoon of ‘Non-Chlorine Shock’ as an emergency cleaner. Just wait 30 minutes after you put the Non-Chlorine Shock in before getting in the tub and it should be just right.


    Draining Your Tub…

    Finally, draining your tub! We recommend changing the water in your tub every 3 months. It can become difficult to handle using just chemicals after this long, so changing the water is just easier. You can drain your tub either, through the 1-inch drain tab inside the cabinet, which you can get to via removing the access panel, or, by using a submersible pump, which we sell!
