What causes black algae in water?

Introduction

Black algae is one of the most stubborn and frustrating things a pool owner can deal with. If you notice any dark spots in your pool, particularly in the shaded areas or areas with a rough surface, it may be black algae. Knowing the reasons for the black algae in the water is the initial step in preventing and curing it successfully. However, a dirty pool or even black algae was not one of your goals, so it is also lucky that you can sweep deep with the help of the Beatbot AquaSense Pro robot pool cleaner and get your pool cleaner without much effort.

In this blog, we’ll discuss the leading causes of black algae in swimming pools and tips for effectively treating and eliminating it with pool vacuums, skimmers, and powerful cleaning robots like the Beatbot.

What is Black Algae?

What is Black Algae? Black algae are a species of algae that enjoy warm and shady areas, often found on pool walls and floors. They form dark spots or patchy areas, typically black or dark green, and cling to rough or porous pool surfaces like concrete, plaster, or grout. Whereas green algae float freely in the water, black algae have strong roots that can burrow into the pool’s surface, making them significantly more challenging to get rid of.

Where does the black algae in pools come from?

Here are a few factors that can lead to an increase in black algae in your pool:

Poor Pool Circulation

The main reason black algae grows is the poor circulation of water in the pool. When water doesn’t circulate evenly throughout the pool, stagnant areas form where algae can prosper. Black algae prefer low water flow areas and are commonly found in corners, cracks, or shaded regions of the pool.

A robotic pool cleaner provides better circulation by properly cleaning every area of the pool, including those difficult-to-reach spots. One option is the Beatbot AquaSense Pro, which uses advanced sensors to concentrate on cleaning and removing algae in the pool.

Improper Water Chemistry

When there is an imbalance in the pool’s water chemistry, algae flourish. Black algae will grow if your pool’s pH, chlorine, and alkalinity levels are not appropriately maintained. In particular, low chlorine levels can allow black algae to take hold more readily. A high or low-pH pool is also more likely to grow algae.

To prevent this, you should regularly test and balance the chemicals in your pool. Use a Robot Cleaner — A robotic pool cleaner, such as the Beatbot AquaSense, cleans debris and eliminates contaminants in your pool that can promote algae growth.

Dirty or Clogged Pool Filters

Dirty or clogged pool filters cause organic matter in your pool to build up, which is a haven for algae. If your filter is not operating properly, it cannot effectively remove debris and contaminants, allowing the black algae to settle and fester.

Cleaning your pool filter regularly and ensuring it’s operating at full capacity are keys to preventing black algae. A pool vacuum robot should also be installed to help with cleaning and debris removal. Product: Beatbot iSkim Ultra keeps your pool clean of dirt and algae.

Improper Maintenance of the Swimming Pool

If not regularly maintained, debris, dirt, oils from sunscreen, lotion, and other contaminants can accumulate on your pool’s surfaces, creating a feast for algae. Black algae will flourish on these surfaces, especially in shaded and poorly circulated areas.

Skimming the water regularly removes leaves and debris, which aids in thwarting algae. It would help if you also had a robot pool cleaner that guaranteed a steady, thorough cleaning process. The Beatbot AquaSense Pro is built to get into every nook and cranny of your pool and effectively scrub algae from the surface.

How to Get Rid of Black Algae in Your Pool？

Brush the Affected Areas

To eradicate black algae, brush the areas with a stiff pool brush. Target the submerged areas of the aquarium: the walls, floor, and elsewhere where algae seems most prevalent. This helps dislodge the algae and makes it easier for your cleaning equipment to remove it.

Use a Pool Vacuum Robot

Use a pool vacuum robot to remove the loosened algae after brushing. Best Vacuum Cleaner For Pool: After brushing the pool with a brush or removing it with a long-handled rake, you can use a vacuum cleaner for the pool, such as the Beatbot AquaSense, to clean the pool’s floor and walls and suck up the remaining algae, dirt, or debris.

Apply an Algaecide

You can treat stubborn spots with black algae algaecide. Use the correct dosage as per the manufacturer’s instructions. When you apply it, let it sit for a couple of hours before running your robotic pool cleaner to eliminate the dead algae.

Shock the Pool

After applying algaecide, shock the pool to kill any remaining algae spores or bacteria. Pool shock is a more concentrated version of chlorine that increases the chlorine level, which in turn kills the algae.

Ensure Routine Pool Maintenance

Keep a regular cleaning schedule to prevent black algae from returning. Invest in a robot pool cleaner like the Beatbot AquaSense Pro, which keeps your pool clean and properly circulated. Make sure to regularly test your pool’s chemistry balance and ensure your filtration system is clean and working effectively.

Preventing Black Algae Growth Checklist

Running your pool pump regularly will help to circulate the water.

Maintain an appropriate chemical balance for your pool, particularly chlorine, and pH.

Regularly cleaning your pool filter is also necessary to properly filter the pool watered.

Use the detailed robot vacuum for pools like Beatbot AquaSense to clean debris.

Skim daily, removing leaves and debris.

Brush the pool surfaces regularly to avoid algae buildup.

Conclusion

Black algae is a problematic pool problem but can be effectively controlled and removed with the right tools and techniques. You can stop black algae from taking over your pool by using a robot pool cleaner like the Beatbot AquaSense Pro and regularly maintaining the balance of chemicals in your pool and circulation. With vacuum, skimmer, and Beatbot products on your side, you can spend less time on maintenance and more time enjoying all your pool brings to the table.
