How Do You Clean a Green Swimming Pool? Here’s What Actually Worked for Me

It happened slowly, then all at once. One day I was lounging by my pool with a drink in hand, soaking in that satisfying shimmer of clean blue water—and the next, it looked like a swamp had taken over. I’m talking murky green, floating gunk, the kind of scene where you’d expect frogs to pop out. I stood there, pool net in hand, totally defeated. I had no idea what went wrong, or more importantly, how to fix it. But somehow, through trial, error, and a little robot named Beatbot AquaSense 2, I pulled off the comeback of the season. If you're staring at your own green pool and wondering where to even begin, maybe my story will save you some time, stress, and a whole lot of chlorine.

Let’s be real: a green pool is disgusting. No sugar-coating it. When mine turned, it felt like the water itself had died. The blue was completely gone, replaced by this dull, unsettling green tint, almost like split pea soup. It didn’t just look gross—it smelled wrong. I didn’t even want my dog near it, let alone dip a toe in.

I did what most people probably do. Googled “how do you clean a green swimming pool” like a maniac. Dozens of tutorials. Hundreds of opinions. It felt like falling into a deep rabbit hole of chemicals, pH balancing, filter checks, pump replacements, and ancient rituals involving pool brushes.

I started out trying to do everything manually. Let me just say—never again.

If you've ever tried to clean a green pool the hard way, you know what I'm talking about. It’s not just physically exhausting; it’s mentally demoralizing. I shocked the pool with chlorine so many times it started to smell like a public gym. I was scrubbing tile like it owed me money. Every time I thought I was making progress, the algae would return like it owned the place.

There were entire weekends where I’d spend more time fighting with the filter than relaxing. And don’t even get me started on test strips. I felt like a failed science student, staring at colors and wondering what they meant for the mysterious “free chlorine levels.”

I reached a point where I seriously considered draining the whole pool and filling it with rocks. But then I stumbled across something on a pool forum that changed the game.

Someone casually mentioned robotic pool cleaners in a thread, and I started reading more. That’s how I found out about Beatbot. The AquaSense 2 series caught my attention mostly because it didn’t look like a clunky machine—it looked kind of… elegant? And smart. I didn’t even know that was possible for a pool cleaner.

At that point, I was desperate enough to give anything a shot. 

So I ordered one.I wasn’t expecting much, honestly. I figured it might help with some debris or lighten the workload. But what happened next kind of blew my mind.

The first time I dropped the AquaSense 2 into the green soup that was my pool, I was skeptical. But then I noticed something: it didn’t just float aimlessly or run into walls like an old Roomba. It actually mapped the pool. It started zig-zagging in this calm, deliberate way, like it knew exactly what it was doing.

No loud motor. No drama. It just quietly went about its business, scrubbing floor tiles, corners, even the waterline, which I had completely given up on. Over the next couple of days, the water started clearing up in a way that no amount of manual labor ever achieved for me.

By day three, I could see the bottom of the pool again. Actual sunlight was bouncing off the floor. I kind of stood there in disbelief, like, “Is this real?”

Okay, I’m not a gadget person. I don’t need an app for everything. But Beatbot’s app was actually kind of helpful. It didn’t overwhelm me with graphs or data—it just gave me gentle suggestions. “Run a cycle today,” or “water temperature’s up, keep an eye on your pH.” It felt more like a friend checking in than a machine bossing me around.

One thing I learned: green pools aren’t just dirty—they’re alive. Full of algae, bacteria, and all sorts of tiny unwanted life forms. You don’t just kill them with chemicals. You have to disrupt the whole little eco-village they’ve set up. And that’s what Beatbot did. It didn’t just clean—it reset the balance.

Before this, I was embarrassed to invite anyone over. I avoided that side of the yard. Even my kids didn’t ask to swim anymore. Now? My neighbor literally asked me if we replaced our pool liner because it looked brand new.

But the biggest shift wasn’t just how the pool looked—it was how I felt. I stopped seeing the pool as a project or a chore. I actually looked forward to using it again. I could relax by the water with a book instead of thinking, “I need to clean that corner before it gets worse.”

And most importantly? I got my summer back.

You’re probably tired. Frustrated. Maybe even a little defeated. I get it. You just wanted a nice place to swim, and now you’ve got a backyard algae lagoon.

But I’m telling you—don’t give up just yet.

The question isn’t just “how do you clean a green swimming pool?” anymore. For me, the better question was: “How do I stop it from turning green again, without losing my sanity?” Beatbot was my answer. Not in a flashy, dramatic way. But in the quiet, consistent way that smart tools are supposed to work.

So yeah, maybe I’m a little too emotionally invested in a pool-cleaning robot. But after what we’ve been through together, can you blame me?

Now, if you’ll excuse me, I’ve got some floating to do. Preferably with a cold drink in hand and absolutely zero worries about algae ever again.
