How to adjust your spa water hardness? The following tips will put the hot tub in a safe and balanced condition which is very important in keeping the equipment constant and durable. There is, in fact, an array of focuses on water care and maintenance, yet it is vital to address one major factor – water hardness in your spa.
The former causes scaling whilst the latter can corrode the interior of a spa or any other water-containing equipment. In this hot tub hardness guide, we’ll explore what water hardness is, why it matters, and how to adjust it to maintain the perfect balance for your spa in 2024.
What is Spa Water Hardness?
Spa water hardness is defined as the amount of mineral content that is specifically, calcium and magnesium in the water.
This standard is generally categorized based on the concentration of these minerals whereby water is referred to as “hard” water or “soft” water. It is calculated frequently in parts per million (ppm).
Soft water: Low calcium and magnesium water which generally has value below 100 ppm.
Hard water: Water with more of these minerals, that is, above 200 ppm.
The water hardness extent in SPA should be in the concentration between 150-250 ppm. Anything beyond this can cause issues to your hot tub and to the body in general.
Why is Spa Water Hardness Important?
Maintaining the proper spa water hardness is essential for several reasons:
Prevents Corrosion: Soft water is water that has low calcium and magnesium ion content and it causes metal to corrode. It can cause corrosion of the metallic parts in your spa; this may encompass heaters, pumps, and jets, all of which will require the salt of your pockets to replace.
Prevents Scaling: A high amount of calcium in hard water begins to deposit itself leading to scaling or what is commonly known as calciation. Scaling occurs in the plumbing of the hot tub, reduces heating, and can deposit an ugly layer on the shell and parts of the hot tub.
Improves Comfort: Normal water is not only beneficial for your hot tub but also for your comfort while in the tub. Soft water has a slippery and slimy feel to it, while hard water makes your skin feel tight and scratchy.
Water Clarity: Uneven water hardness, as in either excess or deficiency, has been known to make water in spas become cloudy or foamy, ruining the tranquility of the hot tub. The setting of the correct hardness levels will help to have clean and clear water.
Step-by-Step Guide to Adjusting Your Spa Water Hardness
Step 1: Test Your Spa Water Hardness
The first thing that you should do in the process of managing the spa water hardness is to determine your current water hardness.
This can be done using a test strip or using a liquid that has been added to the test kit. The test strips are more popular and easier to use while liquid kits will always give more accurate results. To test the hardness:
- Place the test strip into the water and wait till the red line gets immersed in it.
- Take it off and match its color with that of the color chart offered with the kit.
- Refer to Parts 6.2 and 6.3: Record the hardness level in ppm.
- If the hardness level strays outside the range of 150-250 ppm you will have to correct it.
Step 2: Raise Spa Water Hardness
How to Add Calcium Hardness Increaser:
Start your spa and allow water to flow in it.
In the product literature of the calcium hardness increaser, get the correct amount, based on the instruction indicated there.
Usually, it can be about 1 tablespoon per 100 gallons of water to increase hardness by 10 ppm.
Add the product gradually: Add the calcium hardness increaser gradually into the spa water in the latter while the jets are on.
This causes it to dissolve evenly.
This should take about 2-4 hours for the product to distribute itself within the water mass as required.
Check the water hardness to determine if it has reached the required level to get a better reagent and test again.
If your spa water hardness still does not fall within the ideal range repeat the above steps as many times as possible. However, do not put lots of water at once because one can easily set more water than they can remove to soften the water.
Step 3: Lower Spa Water Hardness
If your spa water hardness is over 250 ppm you have to reduce calcium levels as it affects the scaling of the water.
Unfortunately, there is no chemical product in the market that can be directly added to water to soften the water’s hardness. If you don’t have a water softener you’ll have to rely on dilution and water treatment if you wish to filter this particular type of water.
How to Lower Water Hardness
Partial water change: To reduce hardness the most basic procedure is to siphon out some of the water in the spa and then replace it with fresh water that contains less calcium ions. This weakens the concentration of calcium present and the blood loses its ability to absorb calcium from the ingested foods and generate new calcium.
This must be done to turn off the spa and drain water in your spa at about 25-50%.
Rinse with distilled water, if possible, and put an instruction to replace the water with fresh water with lesser calcium hardness. You can use distilled water if this is an issue with you.
Use a pre-filter: If your water is considered ‘hard,’ you’ll want to use a predive filter when filling the spa. This piece connects with the garden hose and removes some of the mineral deposits making the water that gets to the spa softer.
Apply a scale control product: As it is not a means of reducing the calcium level a scale control product can assist in preventing calcium from forming and adhering to your spa’s surfaces and components. These products bind calcium in the water and keep it in suspension.
When preparing the water or after adding the scale control product, leave the water circulating in the spa for a few hours before testing the hardness level again.
If this number is still too high, you should perform a partial water change process again and again until the hardness of water good for fish is attained.
Step 4: Monitor and Maintain Spa Water Hardness
Responsible monitoring after adjusting the spa’s water hardness should be conducted periodically.
You should test your spa water hardness every 1-2 weeks or after refilling your spa or making huge changes. This keeps your water aligned in the correct condition and stops future problems from arising.
Besides hardness, also seeks to control other factors that affect water such as the pH and Alkalinity. The principles highlighted all combine to sustain a healthy spa environment.
Frequently Asked Questions (FAQs)
1. Can I use tap water in my spa?
Yes, but you have to check the hardness level first. In some regions they have hard water, this water may therefore need to be filtered to reduce the amount of calcium that is in the water before use in the spa.
2. What happens if my spa water hardness is too high?
Spa water that has high levels of minerals is not good for the body because it causes calcium scaling a problem that results in clogging of the plumbing, low heat efficiency as well as build-up of deposits on the inner surfaces of the spas. If scaling is not treated it can cause great harm to the regions of your hot tub.
3. How often should I adjust my spa water hardness?
Water hardness is generally only adjusted after it has been replaced in your spa or when water quality is compromised and scaling or corrosion is noticeable. By testing, you can be sure of the adjustments that need to be taken if they are required at all, and can be done after a week or two.
4. What should I do if my spa water is too soft?
If your spa water is too soft, it becomes corrosive and can eat away metal equipment in the spa. With the hardness falling between 100 and 150 ppm utilize a calcium hardness increaser to increase it to the required range of 150-250 ppm.
5. Is there a way to prevent spa water hardness from fluctuating?
But you can’t prevent fluctuation all the time and the best thing you do is use a pre-filter for filling the spa, test the swimming pool water frequently, and maintain your chemical balance (pH & Alkaline) because they help in maintaining hardness levels.
