Hi everyone,

I vacuumed my pool yesterday and noticed the water looked a little cloudy afterward. I tested everything right after using the Eagle Ray Digital Water Testing Kit and the results all looked fine. Chlorine, pH, and everything else came back within range.

Is it normal for water to look cloudy right after vacuuming, even if the chemistry is good? Could it be leftover fine debris or maybe an issue with my filter?

Would love to hear what others have experienced. Just trying to figure out if this is something I need to fix or if it clears up on its own.

Yeah, that’s pretty normal. I’ve had the same thing happen after vacuuming—usually it’s just fine dust or debris getting stirred up. If your filter’s working well, it should clear up on its own in a day or so. I usually run the pump a little longer after vacuuming just to help everything settle and get filtered out. Sounds like your water chemistry is good, so I wouldn’t worry too much unless it stays cloudy.
 
I’ve had the same thing happen after vacuuming—usually clears up after running the pump for a while. Could it be that the filter needs cleaning or backwashing? Also, what kind of vacuum are you using? I’ve noticed some stir things up more than others.
 
Has anyone else noticed cloudy water right after vacuuming, even when all the chemical levels look good? I’m wondering if it’s just fine particles getting stirred up, or could it mean my filter needs a rinse or backwash? How long does it usually take for your pool to clear up after vacuuming?
 
I used to think my robot was haunted every morning the pool looked like a fog machine went wild! Then I started rinsing the filter in the sun for 30 seconds before each run. Suddenly the water cleared up in no time. Who knew sunlight was the secret ingredient?
 
I’ve run into that a few times too, and for me it usually came down to how slowly I was moving the vacuum head. If I went too quick, it kicked up a cloud that looked worse than it was. Slowing down made a big difference because the debris had more chance to get sucked in rather than drift around.

I also found that making sure the water level wasn’t too low helped, if the skimmer is pulling strongly, it clears out the haze faster. Most of the time it settled back to crystal clear within a few hours.
 
I used to wonder about that too! After vacuuming, the water would get a bit cloudy, but everything was normal with the chemicals. It turned out to just be fine dust floating around. I started running the pump a bit longer after vacuuming, and the water cleared up within a few hours. Sometimes, it just takes a little time for everything to settle, so I don't worry about it too much anymore.
 
It’s completely normal to see a bit of cloudiness right after vacuuming, even when your water chemistry is fine. Vacuuming can stir up very fine particles and debris that don’t immediately get trapped in the filter. Usually, running your pump a little longer after cleaning helps these particles get filtered out, and the water clears up within a few hours.

A couple of things that help prevent prolonged cloudiness: make sure your filter is clean, vacuum slowly so debris has time to get sucked up instead of floating around, and ensure the water level allows proper skimmer flow. If the cloudiness sticks around for more than a day, then it could be a sign your filter needs a deeper clean or that adding a clarifier/flocculant might help. Otherwise, it’s just the normal “dust settling” effect after a vacuum.
 
I’ve run into the same thing more than once, and in most cases it’s nothing to stress over. When you vacuum, you’re not just picking debris up you’re also disturbing really fine particles that are light enough to hang in the water for a while. Even if your Eagle Ray test shows chlorine and pH are on point, that haze can linger until the filter cycles it out.

What usually helps me is slowing down with the vacuum so less gets stirred up, then running the pump a few extra hours right after cleaning. Backwashing or rinsing the filter afterward also speeds things up if it’s starting to clog. Some folks even add a clarifier occasionally, but I only bother if the haze sticks around for more than a day.

So in short, yes, it’s normal, and as long as your filter’s in good shape it should settle back to clear fairly quickly.
 
I’ve had that too, the water got cloudy after vacuuming, but after running the pump for a while, it cleared up. If the filter is good, it’s probably just dust or small debris getting stirred up. Give it some time and it should clear up on its own.
 
Yep, that’s completely normal. Vacuuming stirs up fine particles that your filter doesn’t catch immediately, even if your chemistry is perfect. Usually, running the pump a bit longer after cleaning clears the haze within a few hours.

A few tips to help it settle faster:
  • Vacuum slowly so debris gets sucked up instead of just floating around.
  • Check the filter, a clean filter catches more of those tiny particles.
  • Ensure proper skimmer flow so circulation moves the dust toward the filter.
If the cloudiness sticks around more than a day, you might consider a clarifier or a deeper filter clean, but in most cases it’s just temporary “dust in suspension.”
 
Yep, this is totally normal. Vacuuming stirs up fine dust and debris that don’t always get caught immediately by the filter, even when your chemistry looks perfect on the Eagle Ray kit. Usually, if you just let the pump run a bit longer, the haze clears within a few hours.

A few things that help it settle faster:
  • Vacuum slowly so particles get sucked up rather than just swirled around.
  • Make sure your filter is clean, clogged or dirty filters trap less fine debris.
  • Keep the water level sufficient for proper skimmer circulation.
If it’s still cloudy after a day, then you might consider a clarifier or giving your filter a deeper clean, but most of the time it’s just temporary “dust in suspension” from vacuuming.
 
Totally agree with everyone here, a bit of cloudiness right after vacuuming is super common. I actually used to panic every time it happened, thinking I messed up my chemicals, but it’s really just fine debris getting stirred up.

One thing I’ve noticed: if I vacuum right after brushing the pool walls, it almost always looks cloudy afterward because all that loosened dust and algae residue takes a while to filter out. Now I try to brush a day before vacuuming so the filter can catch most of it ahead of time, clears up much faster.

Also, giving the filter a quick rinse before vacuuming helps too. Clean filter + slow vacuum = clear water by the next morning, every time.
 
I’ve had that happen a few times too, especially after vacuuming on a windy day when extra dust or pollen ends up in the pool. The water always looked a bit hazy afterward, even though my readings were fine. I found that adding a little cellulose fiber to the skimmer basket helps a lot, it catches the super fine stuff that the filter usually misses.

Now, whenever I vacuum, I just let the pump run for a few extra hours and check the filter pressure the next morning. Most of the time, it clears up on its own by then. If it doesn’t, that’s usually my sign the filter needs a quick backwash or rinse.
 
Happens to me pretty much every time I vacuum. Even when my Eagle Ray kit shows perfect readings, the pool still goes a bit hazy for a while. I think it’s just super fine dust or silt getting stirred up that the filter needs a little time to catch.

What helps me is letting the pump run a few extra hours after cleaning, and I sometimes toss in a skimmer sock to trap the really fine stuff. Makes a big difference. Usually by the next morning, it’s totally clear again, no chemicals needed.
 
I’ve had that happen a few times too, and it usually depends on what’s sitting at the bottom of the pool before you vacuum. If there’s any really fine pollen, clay dust, or even sunscreen residue that’s settled, vacuuming just stirs it up before the filter has a chance to grab it.

One trick that’s worked for me is letting the pump run for about 10–15 minutes before I start vacuuming. That gets some movement going and helps the filter start catching the loose stuff early on. I also switched to vacuuming in smaller sections instead of trying to do the whole pool at once, that way, I don’t kick up as much debris.

As long as your Eagle Ray readings look good and the cloudiness fades within a few hours, it’s nothing to stress over. If it hangs around for more than a day, then it’s probably just time for a quick filter rinse or backwash.
 
Yeah, that’s totally normal, especially right after vacuuming. Even with perfect chemistry, you’re still stirring up fine dust and tiny debris that can hang in the water for a while. I’ve had the same thing happen, looked cloudy for a few hours, then cleared up once the filter ran a full cycle.

If you want it to clear faster, try vacuuming a bit slower so you don’t kick up as much, and give your filter a quick rinse or backwash afterward. I also like to run the pump a little longer than usual after cleaning, that usually brings the water back to crystal clear by the next morning.
 
Yeah this happens to me too after I vacuum. The water looks kind of cloudy for a while even though the test numbers are fine. I think it’s just little bits of dust or dirt floating around that the filter hasn’t caught yet.

Usually I just let the pump run longer and it clears up on its own. Sometimes I rinse the filter first if it’s been a while, that helps too. Nothing to worry about though, it’s pretty common.
 
Yes, that’s actually pretty common and usually nothing to panic about, especially if your Eagle Ray readings are solid.

What’s happening most of the time is mechanical, not chemical. When you vacuum, you disturb ultra-fine particles (dust, pollen, dead algae, silt) that were compacted on the floor. Those particles are light enough to stay suspended for a while, so the water looks hazy even though everything tests “perfect.”

A few things that can cause or extend the cloudiness:
  • Filter loading up quickly – even if the filter is clean beforehand, vacuuming can push it close to its limit. Once flow drops slightly, fine particles take longer to get trapped.
  • Vacuuming too fast – this kicks debris up faster than it can be captured.
  • Fine debris smaller than your filter rating – it will circulate until it clumps or gets caught later.
  • Return jet turbulence – strong surface movement can keep dust suspended longer than needed.
What usually works best:
  • Run the pump several extra hours after vacuuming
  • Backwash or rinse the filter if pressure rises even a little
  • Vacuum slower than you think you need to
  • If it happens often, a skimmer sock or cellulose fiber can help catch ultra-fine particles
  • Avoid brushing and vacuuming back-to-back unless you plan extended filtration time
As a general rule:

If the water clears within a few hours to overnight, it’s normal.
If it stays cloudy beyond 24 hours, that’s when you start looking harder at filtration efficiency rather than chemistry.

Based on what you described, your pool is behaving exactly how most pools do after a good vacuum session 👍
