Chemical and Maintenance: Weekly Regime

DayCleaning and Chemical Regime
1Circulate the water by switching on your pump. Add chlorine granules or tablets to the water and use a test strip to check the chlorine level. If you’ve sufficiently shocked the water, the test strip should show chlorine levels at 7 – 10ppm.
In order for chlorine to shock the water, you should leave it to circulate for at least an hour and allow 24 hours before using the hot tub. Before entering your Lay-Z-Spa, test the water again. Once chlorine levels are between 3 – 5ppm, you can safely use your Lay-Z-Spa.
2Turn on your pump to circulate the water. Test the water to determine whether chlorine levels fall between 3 – 5ppm. If necessary, add more granules or tablets to bring chlorine levels up. You should use a skimmer whenever any large debris appears in the water. It’s quick, easy and helps to maintain cleaner, healthier water.
3Switch on your pump and allow the water to circulate. Having used your Lay-Z-Spa for a few days now, it’s possible that the chemical balance has been affected by contaminants brought into the water.
As well as showing the chlorine level in your Lay-Z-Spa, test strips indicate the pH level. The pH level should fall between 7.2 – 7.6. If pH levels are too low, use pH Plus to bring the levels up. If pH levels are too high, use pH Minus to bring pH levels down.
After half an hour, retest the pH levels to ensure they fall within the correct boundary of 7.2 – 7.6. If necessary, add more pH Plus or pH Minus.
4Once again, the first thing you should do is turn on your pump. Having tested chlorine and pH levels, it’s time to test total alkalinity. If total alkalinity is too high, your Lay-Z-Spa could develop scale, much like the limescale found in kettles.
As with chlorine and pH levels, you can test total alkalinity using a test strip. Ideally, total alkalinity should fall between 125 – 150ppm. If you’ve treated the water correctly over the past few days, total alkalinity should require very little, if any, readjusting.
If total alkalinity is above 150ppm, you’ll need to bring it down using pH Minus. If total alkalinity is below 125ppm, adding pH Plus can help sort the chemical balance. Retest after a short break to ensure total alkalinity falls between 125 – 150ppm.
Always check chlorine and pH levels when adjusting total alkalinity as changing one factor can have a direct impact on the other.
5As usual, turn on your pump and test pH, chlorine and total alkalinity levels. If the water in your Lay-Z-Spa is looking foamy, now is a good time to use Foam Remover. Foam is formed when dead skin and other contaminants bind together. Foam Remover helps loosen these particles so that they get trapped by the filter cartridge.
6After five days, it’s time to check your filter cartridge. To do this, ensure your pump is switched off, unplugged and the filter hoses have been removed. To prevent water escaping, use stop plugs when unplugging the hoses from your liner.
Remove the filter cartridge from the filter pump. If it’s dirty, give it a light rinse with a garden hose. If this fails to clean the cartridge, you should replace it with a new one. Filter Cartridges for all Lay-Z-Spas are available from here.
7Lay-Z-Spas are smaller than pools and are shared by more people, meaning a greater amount of contaminants are brought into the water. As a result, it’s recommended that you shock treat the water once a week during periods of heavy use.
It’s then a case of repeating our cleaning and chemical regime on a weekly basis.

The ideal chlorine level for a Lay-Z-Spa is 3 – 5ppm (parts per million).
Remember to always wear gloves when handling chemicals and irritants.
Always securely fasten the lid on your Lay-Z-Spa when it isn’t being used.
Always test the water before entering the Lay-Z-Spa.
