Tips For Owning A Hot Tub With Hard Water

If you have hard water in your house and want a hot tub, then you should know that scale is likely to build upon the various parts of your spa. This can be problematic, especially when it comes to your filtration system and the water jets. If you want to keep your spa working well, even when you have hard water, then keep reading for some care tips.

Use The Right Chemicals

If you have hard water, then there are a few things that you will need to test for on a regular basis. You will need to look closely at the total alkalinity. Total alkalinity describes the overall pH of the water and you want a reading somewhere between 80 and 120 PPM. Hard water usually produces a reading that is closer to 150 PPM or even higher. To help remedy this situation, use an additive called a pH or alkalinity reducer. This product comes in granule form and can be added directly to the water. 

Add more of the reducer when tests indicate an increase in alkalinity. Also, when you see signs of hard water issues, then you should also sprinkle in more of the additive. These signs include cloudy water and the apparent buildup of scale on the hot tub. Also, your eyes may feel irritated and so will your skin. You may notice that sanitizers are not working as well as they should either.

Calcium hardness often goes hand in hand with alkalinity and hard water issues. Make sure to test for calcium hardness as well and use a calcium reducing agent in your water. If you do not, then you may be unable to control the total alkalinity. Also, you may notice some corrosion around the metal parts and pieces of the hot tub. 

Drain The Tub

If your water is extremely hard, then it may be impossible to completely control the total alkalinity. This means that you are likely to see some scale buildup in the tub. When this happens and also when you are having trouble with sanitizing the water, make sure to completely drain the hot tub. When you do this, use a cleanser that removes the scale for the tub. 

The vast majority of scale cleaners are acidic, so use them carefully and also make sure to rinse the tub thoroughly when you are done. If you do not want to use chemicals, then you can use vinegar to dissolve the scale buildup. Soak the scale in the vinegar for at least one day to work away as much of the deposits as possible.
