Robot Pool Cleaner — What Are the White Crystals in the Water?
What is calcium scale in pool water?Calcium scale buildup in pools manifests as white crystal deposits in pool water or along tile surfaces. These deposits not only give your pool a cloudy or chalky appearance, but they also can damage pool surfaces and equipment. Fortunately, a robot pool cleaner can help prevent and remove these unwanted mineral builds up.
No matter what type of pool vacuum, skimmer or sophisticated swimming pool robot cleaner you’re using, knowing just what causes this variety of crystals is half the battle to maintaining crystal clear water.
Calcium Scaling, or the White Crystals
Calcium carbonate or calcium silicate scale appears as white crystals in pool water and is caused by:
Calcium hardnes in pool water is too high
High pH or total alkalinity
Heat or exposure to the sun speeds up how quickly things evaporate
Poor water circulation
Crystals can attach to tile lines, ladders and other surfaces. This is a great way to scrub these deposits and keep buildup from happening with a pool robotic pool cleaner.
How A Robot Pool Cleaner/Automated Pool Cleaner Helps In Crystal Removal
A good robot pool cleaner might pick up debris, but it also scrubs walls, floors and the waterline to break down early-stage scaling. These tools help reach all the tight corners and areas that may be prone to buildup, like for example, the pool vacuum robot.
The latest entries into the Beatbot family, including the Beatbot AquaSense 2 Ultra, Beatbot AquaSense 2 Pro, and Beatbot AquaSense 2, employ high-efficiency filtration, smart navigation, and wall climbing pool cleaner technology for targeted cleaning of the most affected spots.
For further coverage to ensure your pool always looks its best, pair your robot cleaner with a vacuum cleaner for your pool and regular water balancing.
Acid Wash Pool: Should You Lid?
If the crystals have built up too much, brushing won’t help. You may have to perform an acid wash on your pool to break down the scaling. That can be time-consuming, but it works.
Also, if your pool must be drained before an acid wash, it’s useful to know how to drain an inground pool without a pump. Read more in this acid wash guide from Swim University, or this method of draining a pool, from The Spruce.
Will A Pool Robot Collect Algae and Crystals?
Most new pool robots, such as on Maytronics pool cleaner, are capable of dealing with light algae and crystals. They function as an excellent pool vacuum for algae as well with their high-efficiency filters and high suction.
You’re wondering, does a pool robot pick up algae? The answer is yes — especially if used regularly and alongside the right chemicals.
Do You Need a Pool Booster Pump? What Is It?
You might also come across a pool booster pump, which is used for pressure-side pool cleaners. The good news? A robot pool cleaner doesn’t need one. They’re fully electric and independent of your pool’s filtration system — meaning they save energy and make setting up easy.
Preventing White Crystals for the Future
Here’s how you can prevent white crystals from forming in your pool again:
Maintain a pH of 7.2 – 7.6
Calcium hardness should be maintained between 200-400 ppm
Daily use of skimmer and weekly use of brush to clean pool surfaces
Choose at least 2–3 times per week to run your robot pool cleaner
Regularly check and clean filters
To ensure the best results, opt for a pool cleaning robot, such as the above-mentioned Beatbot models.
Conclusion: The Robot Pool Cleaner Makes Water Crystal Clear
Though white crystals in pool water may start out as a small issue, if left untreated over time they could cause significant damage. There, a robot pool cleaner such as the Beatbot AquaSense 2 Ultra, Pro or Standard can scrub, vacuum, and otherwise tend to your pool automatically—keeping the scale at bay.
