Is Hard Water Bad for hot tubs?

Last Updated: 23rd April, 2020

26
Hard water contains an extremely high concentration of minerals like calcium. When the spa gets filled with hard water, it can cause filter and spa part failure and/or cause the pipes inside to clog. Additionally, hard water is not just harmful for the body of your spa but also can affect your skin.

In respect to this, can I put well water in my hot tub?

If you are filling your hot tub with well water, you will need to make sure that the minerals present in the water will not cause staining or damage to your hot tub. Add Eliminate to the water to prevent this from happening.

Subsequently, question is, how do I adjust the hardness of my spa water? If your hot tub's calcium hardness level drops below the recommended 150 ppm the easiest and most common way to raise calcium hardness is by adding a calcium hardness increaser such as calcium chloride to your hot tub.

In respect to this, is it safe to swim in hard water?

Hard water can cause damage to your pool and result in white residue left on ladders, pool decks and other surfaces. This is known as "scaling" and is the result of calcium hardening on a surface. According to Pool Center, water balance is a term used to describe water that is neither scaling nor corrosive.

How do you lower water hardness?

We first have to remove the mineral from the water before we can effectively lower the pH. To soften hard water, you need to take the mineral out with a natural "water softener" such as Sera Super Peat. Another option is to use demineralized water for your fish tank.

Why is soft water bad for hot tubs?

Calcium and magnesium are the minerals that most directly contribute to water hardness. Hot tub water that is too soft can be corrosive to metal while water that is too hard can cause damaging scaling.

What happens if calcium hardness is too high?

The Effects of High and Low Hardness
As mentioned, the excess calcium carbonate will precipitate as crusty, grayish white scale on surfaces, piping, and equipment. It's unsightly, can cause abrasions on users and snag bathing suits, and makes a good anchor for microorganisms. It will clog filters.

What is calcium hardness in hot tub?

Total Hardness is a measure of the amount of dissolved calcium and magnesium in the hot tub water. The basic recommended range in a hot tub is between 200 and 400 parts per million. This can vary depending on the hot tub finish and chemicals you are using to treat your spa.

What are the white flakes floating in my hot tub?

Cause of white flakes
There are two primary causes of the formation of white flakes in your hot tub: calcium scale deposits and biofilm. Calcium scale deposits occur when there's an excess of calcium in the water, also known as hard water. As calcium accumulates in the water over time, white flakes will start to form.

How do you check water hardness?

Water hardness can be easily measured using a simple soap test kit that will measure in "grains of hardness" (a little bottle with a line marked on it which you fill to the line with water, add a drop of soap, and shake to look for suds. More drops of soap - more degrees of hardness).

Can I put water softener salt in my hot tub?

The good news is yes, you can! Salt-water systems can safely be used in hot tubs, and have the same benefits that they do in pools. Fans of salt water systems report that they are cheaper in the long run, result in softer skin, make it easier to balance the pH of the water and are easier to maintain!

How do I lower the calcium in my pool?

Reducing Pool Calcium Hardness Levels
  1. Place the filter system on Recirculate or remove filter media.
  2. Raise the pH to 10.0 by adding ph Increaser.
  3. Circulate pool for 8-12 hours, water should be cloudy, retest pH using diluted sample*.
  4. Shut off filter system for 8-12 hours, allowing precipitate to sink to the bottom.

How soon can you use hot tub after adding chemicals?

How long do you have to wait to get into your hot tub after shock dosing it? If you are shocking the spa with Non Chlorine Shock then allow 10 minutes for it to all mix in and get right in. If you are using Chlorine granules then you must wait until the Chlorine level has returned to 5 PPM which may take 24 hours..

How do I get iron out of my hot tub?

Treating Metal Problems
  1. Shock treat the water.
  2. Vacuum away the waste that settles on the bottom of the pool or hot tub.
  3. Partially drain and refill the water.
  4. Use Sea Klear Metal Control to keep suspended metals from staining your hot tub or pool surfaces in the future.

What is ppm stabilizer in a hot tub?

Stabilizer. Under the sun, chlorine in your pool or hot tub becomes very unstable. Stabilizer is a chemical that slows down the rate at which chlorine reacts in the water. It will be effective if the amount in your water is kept between 40 and 80 PPM (Parts per Million).

What is total water hardness?

The hardness of your water is a measure of the amount of lime dissolved in the water. Water with a calcium hardness of less than 100 ppm (mg/l) is described as soft water. The guideline figure for total hardness of the water is 100-300 ppm (mg/l).

How do you remove metals from spa water?

Metals
  1. Attempt to remove as much of the metals in your water as possible, using a chelator.
  2. Try to pick a cooler day and let your chlorine level drop to below 1 ppm.
  3. Be sure to turn off all automatic systems, bypass the heater and other equipment, but leave filter system operating.

How do I raise the alkalinity in my hot tub?

There are two ways to increase your hot tub's alkalinity level: sodium bicarbonate (baking soda) or any type of alkalinity increaser product. If you choose to purchase an alkalinity increaser product be sure the product is made from sodium bicarbonate, which is the main substance used to raise pH.

Can high pH in pool cause rash?

If the pH gets higher than 7.8, the water is becoming too alkaline. When water is too alkaline, it reduces the effectiveness of the chlorine — the pool chemical that kills pathogens. Water with a pH that's too high also can cause skin rashes, cloudy water and scaling on pool equipment.

What causes the pH level in a pool to be high?

An increase in the pH level can be caused by several things. A first cause is the addition of chlorine stabiliser or HTH Granular to the pool water. A higher pH level can also be caused by a sudden rise in temperature of the water. However, much more important than the causes are the effects of such a high pH level.

Why is pH important in water?

pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.

Can you swim in a pool with high pH?

In addition, high pH runs a risk with your chlorine, as your chlorine will no longer disinfect fully. There are also physical consequences of high pH for swimmers. Red irritable eyes, dry skin and premature wear and tear of goggles and bathing suits are often indicative of a high pH level.
