FAQ spa maintenance

Want to de-stress in your lovely heated spa after a long working day, but find you have green water? Of course not! By maintaining the water and your spa properly, you need to change the water less often and you need fewer maintenance products. So you can quickly bubble away in a clear hot tub again! In this blog, we answer the most frequently asked questions for a clean spa!

How should I install the Intex PureSpa?

1. Place the groundsheet where the spa will be placed
2. Connect the hose to the unit and the spa and inflate it. This takes about 5 minutes.
3. Then blow the lid.
4. Disconnect the air hose and connect the unit to the spa. That unit will take care of heating the water and filtration. Make sure everything is connected before you start filling the spa!
5. Fill the spa with water. Never go above the maximum line, otherwise the spa will overflow as soon as you start chilling in it.
6. Cover the spa with the cover while heating up. This will speed up the process!
7. Is the spa warm enough? Then add a chlorine tablet to the chlorine float and keep a close eye on the water values!

Have you chosen one for a PureSpa with a built-in saltwater system?

8. Switch on the filter pump.
9. Keep the saltwater system switched off.
10. Distribute the salt evenly throughout the spa water.
11. Brush the bottom so the salt dissolves faster.
12. Run the jets for an hour to fully dissolve the salt.
13. When the salt is fully dissolved, let the saltwater system start. Set the desired running hours.

How should I install the Lay-Z-Spa?

1. Connect the hose to the unit and the spa and inflate it.
2. Then inflate the lid.
3. Disconnect the air hose and connect the unit to the spa. That unit will take care of water heating and filtration.
4. Insert the filter catridge into the part provided for it in the spa. Tighten securely.
5. Above the cartridge comes the ChemConnect, which releases chlorine into the water.
6. Fill the spa with water. Never go above the maximum line, otherwise the spa will overflow as soon as you start chilling in it.
7. Cover the spa with the cover while heating up. This will speed up the process!
8. Check again that the pipes don't leak!
9. Wait for the desired temperature to be reached.
10. Time to take a dip! Disconnect the ChemConnect while bubbling, so that the chlorine is not released further while bathing.

By the way, did you know that Jacuzzi is a protected brand name? This name is so ingrained that many people call all spas that, but actually they are simply called spa or hot tub. At Hermie, you will therefore find many models from various brands under these designations.

How to keep water healthy & clear?

Good water values are the basis for a healthy & fresh dive! Measuring is knowing, so keep a close eye on pH, alkalinity and chlorine values and make regular adjustments. These values need to be in perfect balance for the maintenance products to do their job properly! In our starter kit, you will find everything you need to kick off the spa season!

What are good water values?

  • pH: 7,2-7,6
  • Chlorine: 1,5-2 ppm

So test the water values regularly (min. 1x/week) with our handy test strips!

Why is there foam on the water?

Foaming water is usually caused by too hard water. Fortunately, you can easily fix this with a foam remover!

pH imbalance and chemical overdose are also culprits. So check water values regularly and make adjustments to keep in balance.

Finally, it is important to rinse your swimwear thoroughly before going into the spa and use as little and mild detergent as possible. Residual shampoo in your hair can also cause foam.

How should I maintain the filter pump?

The filter pump is the engine of your spa, so maintain it properly! Do you have a cartridge filter pump? Then rinse the filter daily and replace the cartridges on average once a week.


Poolboy Marcel's budget tip: reuse your filter up to 3 times thanks to the following tips

• Clean the filter thoroughly with water after use and leave to dry for a week.
• If possible, blow off the dust and scale with a compressor.
• Then put the filter in the freezer for a week. This will kill any bacteria or remaining algae. After that, it is ready for reuse!

And what about a saltwater system?

With a saltwater system, the salt is converted into natural chlorine. Check the pH well first and then top up the salt.

How often should I change the water?

Change the water every 3 to 4 months. You can do this effortlessly thanks to a submersible pump, or connect the garden hose to your spa's drain.

Do not let the water drain into the garden as it contains a lot of products & chemicals. This can be pernicious for nature. Don't forget to clean the spa pipes when you change the water. Because a lot of dirt can collect there too!

Tip to enjoy your fresh water longer

Before diving into the jacuzzi, rinse your bathing clothes! There may still be all sorts of detergent residue in them. These go into the spa with you, which can change the water values and also make your water dirty faster. By briefly rinsing yourself and your swimwear, you also rinse away other personal care products, such as body lotion or sunscreen.

Not only should the water be clean, don't forget the bottom & walls of your spa!

Thanks to a flocculant, all the dirt particles in your pool stick together at the bottom. So you can easily vacuum up the dirt with a spa hoover. The walls can also use a scrub regularly! Use a soft cloth or special sponge to clean the spa walls. You will find all kinds of cleaning kits especially for your hot tub.

More energy-saving tips?

Besides a cover, we have a few more tips for you to get your energy bills down:
• Do you use the hot tub several times a day? Then it is better to keep the temperature at 30°C continuously. This is because it takes a lot of energy to reheat the water!
• Provide an insulation layer under the bottom of your pool by placing protective floor tiles, for example.
• Place your spa in a sheltered spot.

Pimp your spa!

Fancy a cosy movie night at the spa? At Hermie we have everything you need! Think of a cup holder, tray for your tablet, LED lights, comfy cushions and seats... You only have to provide the popcorn yourself!
