Are you starting to see undissolved minerals? That’s probably due to an imbalance in the calcium level.
Read this article and figure out how to increase hardness in hot tub and say goodbye to all your problems.
Why Is Having a Balanced Calcium (Lime) Level Necessary?
The presence of calcium and magnesium ions in hot tub water chemistry is what keeps the calcium level balanced, required for hot tub care.
Keeping the hardness level stable is as easy as maintaining chlorine, alkalinity and ph level.
But why should you care? Well, if your source water is too hard or soft, it cannot dissolve minerals.
So, when you see corroded metals, scale build-up, cloudy water at the surface of your pool and spa, or feel any irritation, know that your calcium level is high or low.
How to Increase Calcium Hardness in a Hot Tub?
When the calcium level is disrupted(below 100 ppm), acidic compounds could start corroding your hot tub’s interior. So, be alert and act swiftly.
Start by adding water softener in small increments, maintaining mineral content, ph and alkalinity of spa water.
For alternatives, you want to add calcium hardness increaser (calcium chloride), made specifically for hot tubs to boost calcium levels.
How to Lower Calcium Hardness in a Hot Tub?
Did you know that high calcium level causes tub filters and pipes to form calcium deposit (calcium carbonate)? Follow these steps and lower calcium hardness faster.
Above 250 ppm
Immediately drain the hard water if the calcium level exceeds 250 ppm( parts per million).
Use a hose filter to fill your hot tub, preventing excessive minerals from entering the water.
Keep the jets running to maintain optimal water hardness while adding scale control products.
Put test strips and see if the spa water contains adequate chemicals.
Below 250 ppm
If the hardness level is low (near 250 ppm), refill with fresh water and add a scale control product. Test hardness to keep the calcium level in check.
Test for Calcium Hardness in Your Hot Tub ASAP
Prevent corrosion and mineral build-up by testing the hardness level of calcium beforehand. Here are some tips on how to do so.
Test Strips: This is a budget-friendly yet quick testing method. Soak the test strip in water and ensure it includes total hardness.
Liquid Test Kit: Best for accurate testing and offers advanced scaling. Add hot tub water to the test kit to monitor the calcium hardness level.
Professional Help: Get your water professionally tested frequently to check water quality.
Whack The Softness Away!
Wasn’t learning about calcium levels fascinating? Let’s go over some important points together.
The level of hardness dictates if the water is hard or soft. To prevent high pH levels and enable the sanitizer to protect the hot tub, test the water and prevent scaling to enjoy a surreal bather experience.
