Having hard water means that your water has a lot of calcium, and it can leave deposits in your shower and sinks.
In most cases, a little bit of scale is no problem, but occasionally, calcium hardness levels can get too high that can cause problems.
A lot of the time, hard water problems in hot tubs can start when the calcium in the water comes out of solution. This can cause scale deposits to form in the water and can affect other parts of the spa.
The map of the US shows that water with a high concentration of hardness is considered extremely hard. However, many hot tubs and spas can effectively operate at elevated levels.
If your spa has hard or soft water, you can easily check it with a test kit or strips that measure calcium hardness. Most hot tubs and spas will allow up to 400 ppm calcium hardness.
If your hot tub's water has a hard calcium content, then you should probably check the scale deposits. They can also appear in other parts, such as the filter and heater.
High calcium levels in hot tub water can cause illness and scale deposits.
High temperatures can cause excessive calcium to build up in the hot tub, which can affect water quality and sanitation. This issue can also cause scale deposits to appear.
Treatments for Hard Hot Tub Water
There were times when it was impossible to manage hard water levels in a spa. Fortunately, there are ways to do it successfully, such as keeping the pH and Alkalinity levels at a low and moderate level.
- Filter the Calcium. You can use this filter to remove calcium from the water. It's also a good idea to filter the water coming from outside the home. The Pleatco Spa Water Pre-Filter will remove chlorine, chloramines, and other impurities from your water. It works by trapping sediment and removing metals, chloramines, and foul odors.
- Combine the Calcium. CalTreat is a pool chemical that bonds to calcium carbonate. When combined with the calcium, it produces a large enough particle to be removed from the filter. Follow the instructions carefully to reduce calcium hardness levels. It can take up to 2 weeks to see results, and if you do it correctly, you may reduce them by up to 200 ppm.
- Control the Calcium. Spa Metal Out and calcium are chemicals that keep mineral deposits and calcium in the solution tied-up, which prevents them from slating out and creating crystals. They can also remove scale deposits from filter cartridges and heater elements.
Treatments for Soft Hot Tub Water
Soft Water and Hard Water are both common issues for spa and hot tub owners. If you live in a purple, blue, or white area, add a Calcium Hardness increaser to your water to prevent further damage.
Soft water can cause staining and scale on the surface of your hot tub. It can also cause excessive spa foaming.
When your spa or hot tub's calcium content is less than 150 ppm, add Calcium Hardness Increaser to keep it at a high level. This will help maintain the proper water balance and prevent spa foam.
