How to Get Rid of Algae in Pool Quickly？
One of the most common challenges pool owners experience, particularly in the warmer seasons, is algae growth. Not only does it make your pool appear dirty and uninviting, but it can also clog your pool’s filtration system and cause surfaces to become slippery. Luckily, robot pool cleaners can be one of the fastest and most effective ways to kill algae and stay on top of debris in your pool. In this guide, we’ll discuss how to get rid of algae fast, the best tools to have on hand for the task, and how to prevent algae from returning in the future.
Why Algae Grows in Pools
Sunlight, poor circulation, and unbalanced water chemistry make for perfect conditions for algae to flourish in pools. Here’s why algae may be invading your pool:
Low chlorine levels – Chlorine kills algae.
Poor circulation: If your pool pump or filtration system isn’t functioning correctly, algae spores will settle and hatch.
High pH – When pH is high, chlorine is less effective
Dirty pool surfaces — Algae can cling to walls and floors, particularly in crevices and corners.
How to Remove Algae from Pool Fast
✅ Step 1: Shock Your Pool
The quickest way to kill algae is through a pool shock treatment. The shock of the pool increases chlorine to a level that destroys algae and bacteria.
For green algae, shock with calcium hypochlorite.
A firmer shock may be required for mustard and black algae.
Let the pool pump run for at least 24 hours after the shock to help mix the water and evenly spread the chemicals.
✅ Step 2: Employ a Robotic Pool Cleaner
After shocking the pool, dead algae will sink to the bottom and stick to the walls. This is when a robot pool cleaner is necessary. A robotic pool cleaner will clean the walls and floor, vacuum up debris, and filter out even small particles of algae.
Top Picks:
Beatbot AquaSense 2 Ultra—The suction is powerful, and dual scrubbing brushes are present for strong algal growth, such as green algae or mustard algae.
Beatbot AquaSense 2 Pro: Suited for hardcore algae, this one features intelligent navigation and wall-climbing.
Maytronics pool cleaner – Fast cleaning cycle and reliable performance.
✅ STAGE 3: BRUSH AND SCRUB THE POOL
While a robotic pool cleaner will do most of the scrubbing for you, brushing the walls and corners of the pool loosens algae, especially mustard and black algae.
Use a stiff pool brush on plaster or concrete pools.
For vinyl or fiberglass pools, scrub with a soft nylon brush to avoid scratches.
✅ Step 4: Vacuum the Pool
If the robot doesn’t remove all the debris, you might have to pass over what’s left with a pool vacuum manually.
A pool vacuum removes acceptable debris and dead algae from the pool bottom.
Large pools should always have a vacuum robot for faster and more effective cleaning.
✅ Step 5: Clean the Filter
Algae can instantly choke up your pool’s filter, which lowers efficiency. After vacuuming to clean, scrub any things you scrubbed, and, to prevent the algae from returning, clean or backwash the filter.
Cartridge filters – For those, remove and rinse thoroughly.
For sand filters — Backwash and rinse.
For DE filters , clean them and add new DE powder.
The Role of a Robot Pool Cleaner in Algae Eradication
Here are some specific reasons why a robot pool cleaner is excellent at getting rid of algae:
✔️Independent Operation – functions independently of the pool’s filtration system, lessening the burden on the pump.
✔️ Advanced Navigation – For entire wall and waterline coverage
✔️ Powerful Suction and Scrubbing – Cleans algae and debris from the pool’s surfaces.
✔️ Ultra-Fine Mesh Filter – To filter out the smallest possible algae.
⭐ Top 5 Recommended Algae Removal Models:
Beatbot AquaSense 2 Ultra Powerful suction and deep cleaning遣
Beatbot AquaSense 2 Pro – Best for big pools and tough algae.
★ Maytronics Dolphin Nautilus CC Plus – Effective on green and mustard algae.
How to Stop Algae from Returning
After clearing away the algae, do the following to prevent it from coming back:
➡️ 1. Keep Chlorine Levels in Check
Test your pool water regularly and keep the chlorine level between 1.0 and 3.0 ppm.
➡️ 2. Keep pH Levels Balanced
For maximum effectiveness, ensure your pH level is between 7.2 and 7.6.
➡️ 3. Improve Circulation
Ensure you run your pool pump for 8–12 hours daily to keep the water circulating.
➡️ 4. Robot Pool Cleaner Clean Regularly
Use a swimming pool robot cleaner at least twice weekly to uproot debris and maintain the walls and floor algae-free.
What If the Algae Just Keeps Coming Back?
Algae Keeps Growing During Regular Maintenance:
➡️ How to Acid Wash Pool: Acid washing can remove stains caused by stubborn algae in concrete and plaster pools. It consists of draining the pool and treating the surface with muriatic acid. This can only be performed by a professional.
➡️ How to Drain an Inground Pool Without a Pump: Use a garden hose to siphon out water, or use a submersible pump to drain the pool.
➡️ What Is a Pool Booster Pump? A booster pump increases the water output pressure for pressure-side pool cleaners, but it’s unnecessary for robotic cleaners.
The Best Choice for Algae: A Robot Pool Cleaner
✅ Stand Alone – This does not require the pool’s filtration system to be operable.
✅ Powerful Suction and Scrubbing — Effectively eliminates algae and acceptable debris.
✅ Advanced Navigation – Covers 100% of the floor, even corners and walls.
✅ Minimal Maintenance – Easy to maintain and clean after every use.
Conclusion: How to Get Rid of Pool Algae Fast
Using a robot pool cleaner is one of the fastest and most effective ways to eliminate algae. Models such as Beatbot AquaSense 2 Ultra and Beatbot AquaSense 2 Pro enable advanced cleaning, keeping your pool clean of algae.
Regular maintenance, chemical balance, and cleaning tools are all vital to keeping algae from coming back. The best pool cleaning robots, like the Beatbot AquaSense 2 and Maytronics pool cleaner, are investments that save you time and energy in keeping your pool crystal clear.
