After dealing with endless algae blooms, murky water, and the ongoing ritual of scooping, shocking, and scrubbing my pool like it was a second job, I was ready to try anything that could make pool maintenance easier. That’s when I stumbled across Krazy Klean, a little metallic ball that claims to use “ionic mineral technology” to keep your pool sparkling without harsh chemicals.
It sounded too good to be true. But with summer coming and pool parties on the calendar, I decided to give it a shot. Here’s how that went.

What Is Krazy Klean Supposed to Do?
Krazy Klean is a baseball-sized mineral sphere that you drop into your pool or spa. According to the company, it uses copper and silver ions to prevent algae growth and reduce the need for chlorine by up to 90%. It’s marketed as a safer, eco-friendly alternative to traditional pool chemicals and as one that works passively for up to 6 months. No measuring. No mess. No constant chemical balancing. Just drop it in and relax.
Why I Decided to Try It
To be honest, my main motivation was laziness. I hate spending weekends testing pH, adjusting chlorine levels, and hauling buckets of chemicals around. I also have sensitive skin and occasionally react to pool chlorine, so the idea of reducing my reliance on it was appealing.
Plus, at around $50, it felt like a relatively low-risk experiment. If it didn’t work, I’d go back to the old routine. But if it did, it could save me money and time.
My Experience Using Krazy Klean
I dropped the Krazy Klean ball into the skimmer basket and waited. For the first couple of weeks, I was cautiously optimistic as the water stayed clear, and I didn’t notice any algae growth even after some heavy rain. I still used a small amount of chlorine, just in case, but far less than usual.
By week four, though, things got murkier, quite literally. Despite the ball being in place, I started seeing green patches on the pool steps. The water lost that crystal-clear look and started looking slightly cloudy, especially on hotter days. I checked my chlorine levels and realized they’d dipped way too low.
It turns out Krazy Klean doesn’t replace chlorine as it only supplements it. And unless you’re closely monitoring your water chemistry, you can’t rely on it to do all the work.
Also, the ball itself looked off. It had a kind of tarnished, discolored appearance after just two months, and I wasn’t sure how much longer it would actually last.
Pros and Cons of Krazy Klean
Pros:
- Easy to use as you just drop it in
- Can help reduce chlorine usage (but not eliminate it)
- No batteries, no tech. You just set it and forget it (sort of)
- May help prevent some algae growth when used with chlorine
Cons:
- Not a full replacement for pool chemicals
- Doesn’t work well in high-heat or high-use pools without backup
- Can tarnish or degrade before the promised 6 months
- Expensive for what it delivers (about $50 per unit)
What Other Customers Are Saying
Customer reviews online are split. Some swear that Krazy Klean keeps their pool crystal-clear all summer with minimal chlorine. But others, especially in hotter climates or with heavy pool usage, report the same experience I had: a promising start followed by murky water and the return of algae.
On Amazon, it has mixed ratings, and several users mention that it doesn’t last the full season or needs to be paired with chemicals to work effectively.
Tips If You’re Going to Try It
- Don’t ditch your chlorine entirely. This is an additive, not a magic bullet.
- Keep an eye on pH and chlorine levels. Krazy Klean doesn’t monitor anything.
- Replace it every 4–5 months, not 6, especially if your pool gets a lot of sun or use.
- Use it as part of a multi-step system, not your only solution.
Where to Buy Krazy Klean

Conclusion: Would I Recommend It?
Krazy Klean is not a scam, but it’s not magic either. It’s a decent chemical aid, one that might help slightly reduce your chlorine usage but it’s not going to clean your pool for you. If you go into it thinking it’ll replace your maintenance routine, you’ll probably be disappointed.
But if you’re okay with using it as a supplement and still doing regular upkeep? Then sure, it can earn a place in your pool toolkit. Just don’t toss out your test strips and chlorine tabs.
