Arizona’s hard water is a major challenge for pool owners, leading to calcium buildup on pool tiles, surfaces, and equipment. If left untreated, calcium deposits can make your pool look unattractive, damage your equipment, and become difficult to remove. Understanding how to manage and prevent calcium buildup is essential for maintaining a clean and well-functioning pool. Here’s everything you need to know about pool calcium removal in Arizona.
What Causes Calcium Buildup in Pools?
Arizona’s water is naturally high in calcium and other minerals, which can accumulate over time in your pool. Two main types of calcium deposits affect pools:
- Calcium Carbonate: A white, flaky deposit that is easier to remove.
- Calcium Silicate: A harder, more stubborn buildup that requires stronger treatment.
These deposits form when water evaporates, leaving minerals behind on pool tiles, surfaces, and even equipment. High pH and alkalinity levels can accelerate calcium scaling, making regular water chemistry maintenance critical.
Signs Your Pool Has Calcium Buildup
If you notice any of the following, it may be time for a calcium removal treatment:
- White or grayish scale buildup along the waterline, tile, or plaster.
- Rough, chalky surfaces on pool walls and steps.
- Reduced water circulation due to calcium clogging filters or pipes.
- Cloudy water caused by excessive dissolved calcium.
How to Remove Calcium from Pool Tiles and Surfaces
1. Pumice Stone Scrubbing
A pumice stone is a simple and effective way to remove minor calcium buildup from pool tiles and surfaces. Gently scrubbing the affected areas can help break down deposits, but this method is labor-intensive and best suited for smaller areas of buildup.
2. Acid Washing for Severe Buildup
If calcium scaling has become widespread or deeply embedded in plaster, an acid wash may be necessary. Acid washing removes a thin layer of plaster along with the calcium deposits, restoring the pool’s surface. This process should only be performed by professionals to avoid damage to the pool structure.
3. Bead Blasting (Calcium Blasting)
One of the most effective ways to remove calcium deposits from pool tiles is bead blasting (also called glass bead or soda blasting). This technique uses fine media, such as glass beads or salt, to gently remove scale buildup without damaging tiles. This is the preferred method for restoring the clean, smooth look of pool surfaces.
4. Chemical Treatments
Certain chemical treatments, such as calcium removers and descalers, can help break down calcium deposits over time. These treatments are best used as a preventative measure rather than a primary removal method.
How to Prevent Calcium Buildup in Arizona Pools
Since Arizona’s hard water constantly introduces new minerals into your pool, prevention is key. Here are a few strategies to minimize calcium buildup:
- Maintain Proper Water Chemistry: Keep pH between 7.2 and 7.6 and alkalinity between 80-120 ppm to prevent excessive calcium scaling.
- Use a Pool Cover: Covers help reduce evaporation, which slows down calcium buildup along the waterline.
- Regular Brushing and Tile Cleaning: Light brushing and maintenance can help prevent calcium from becoming a thick, stubborn layer.
- Consider a Water Softener or Reverse Osmosis Treatment: For pools with extreme calcium hardness, treating the fill water before adding it to the pool can reduce the introduction of excess minerals.
