It’s imperative not to let your hot tub’s calcium hardness dip too far below 150ppm. 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.
Does baking soda raise calcium hardness?
In the case where too much baking soda is added to hard water, it can cause a build-up of calcium around your pool.
How do you increase hardness in water?
Add half tablespoon of epsom salt to the distilled water. Stir well to completely dissolve the salt and make a clear solution. Calcium chloride increases the permanent hardness of water. Add half tablespoon of baking soda to the solution.
What happens if water hardness is too low in hot tub?
If your spas hardness level is low, you can experience plaster etching, equipment, jet and plumbing corrosion.
How much baking soda do I add to my hot tub?

What chemicals increase calcium hardness?
You can raise water’s calcium hardness easily by adding calcium chloride (CaCl2). Two forms are sold: hydrated (77% strength) and anhydrous (100% strength). Each will generate heat when contact with water is made.
Does epsom salt make water hard?
The minerals that make water hard usually contain calcium and magnesium. In this experiment, you made water hard by adding epsom salt, which is magnesium sulfate. They do this by combining with soap or detergent and forming a scum that does not dissolve in water.
Can you make soft water harder?
People can make soft water harder by adding a water hardener to their water, but some caution is advised when using a water hardener, depending on how the water is being used. Because soft water contains sodium, it’s advisable to filter it or use a better source of drinking water.
What is pool hardness increaser?
In the Swim Pool Calcium Hardness Increaser is a great way to resolve low hardness levels. To fulfill the need of the water, add Calcium Hardness Increaser to raise the calcium hardness. The ideal range is 200 – 400 ppm. Product is average 97% granular calcium chloride.
Does calcium hardness affect pH?
Alkalinity and calcium hardness don’t fluctuate nearly as much as pH or chlorine so monitoring them only needs to be done once a day, and can be checked using a titration kit, or a photometer. Just remember, the higher you go, the harder time you will have affecting change on your pH, in either direction.
Does hardness matter in hot tub?
Calcium Hardness is an important measure in hot tub water chemistry but one that is sometimes overlooked or ignored. If this is extremely high or extremely low, it can have quite serious consequences with component damage, skin & eye irritation and scaling all common with an unbalanced hardness level.
Should I fill my hot tub with soft water?
Hard water can cause scale – a layer of deposit – on the hot tub. Obviously neither of these results is optimal. So it’s important whether you fill the tub with soft or hard water to maintain the chemical levels in your tub.
What does baking soda do for a hot tub?
Baking soda can assist you in keeping the pH level of your water in the proper zone. Baking soda can be quite helpful to homeowners who have hot tubs, as it can assist them in keeping the pH level of the water in the proper zone. As many homeowners know, the ideal pH for a hot tub or pool should be between 7.2 and 7.8.
How do you soften hot tub water naturally?
Fortunately, the easiest way to raise calcium hardness in a hot tub is to—you guessed it—add calcium to the water. Actually, you want to add calcium chloride, which is the active ingredient in calcium hardness increaser made specifically for hot tubs.
Can I use baking soda instead of alkalinity up?
Baking Soda for Pools: An Easy Way to Raise pH and Alkalinity. Don’t waste money on commercial alkaline-increasing pool products when you can use baking soda to raise your pool’s pH and alkalinity instead.
How do you fix low hardness in a pool?
How to Lower Calcium Hardness in Your Pool Drain and replace some water. Before you replace the water, test your water source. Use pool flocculant. If you can’t or don’t want to drain any water from the pool, try using pool floc to clump the excess calcium. Try muriatic acid.
What happens if pool hardness is low?
Low calcium levels will ruin your pool’s alkalinity. This will, in turn, corrode metal items. Your pool’s railing and mechanical parts could become damaged. Thankfully, it’s easier to raise water hardness than lower it.
Does baking soda make hard water soft?
