How to Protect Your Pool During Georgia's Pollen Season

Every March, Georgia earns a distinction no other state really wants: the yellow-green apocalypse. Pine pollen rolls in like a slow-motion fog, coating cars, driveways, patio furniture, and — most frustratingly for pool owners — every square inch of pool water surface in your backyard. If you have lived in Cherokee, Cobb, or Paulding county for even a single spring, you know exactly what I am talking about. One morning your pool looks fine, and the next it looks like someone dumped a bucket of highlighter paint into it.

I am Corey Adams, owner of Peachy Pools, and I have been servicing pools across North Georgia for over 15 years. Pollen season is, without question, the single biggest maintenance challenge Georgia pool owners face outside of summer algae blooms — and in many cases, the two are directly connected. A pool that is not properly managed through pollen season in March and April is a pool that tends to turn green in May.

This guide covers everything you need to know about protecting your pool during Georgia's pollen season: what pollen actually does to your water, a step-by-step maintenance strategy, the chemical adjustments that make a real difference, and a North Georgia pollen timeline so you know exactly when to ramp up your routine.

How Pollen Actually Affects Your Pool

Most pool owners think of pollen as a cosmetic nuisance — that yellow film on the surface that makes the pool look dirty. But pollen's impact goes far deeper than appearance. It is an organic material, and organic material in your pool sets off a chain reaction that can compromise water quality, strain your equipment, and create the conditions for a full-blown algae bloom.

When pollen lands on the water surface, it initially floats. Your skimmers catch some of it, but during peak weeks the volume overwhelms what a typical skimmer can handle in an 8-hour pump cycle. The pollen that is not skimmed breaks apart and sinks, becoming suspended organic matter that your filter now has to deal with. This is where the real problems begin.

As pollen breaks down, it consumes free chlorine. This is the same process that happens with any organic contaminant — leaves, grass clippings, sunscreen — but the sheer volume of pollen during a Georgia spring makes the chlorine demand enormous. I have tested pools in Canton and Woodstock where the free chlorine dropped from 3 ppm to nearly zero in 48 hours during peak pine pollen, with no swimmers in the pool and no other obvious contaminant source. The pollen alone ate through all of it.

Pollen also introduces phosphates into your pool water. Phosphates are a nutrient — food for algae. Even if your chlorine is holding steady, elevated phosphate levels create a more hospitable environment for algae to establish itself the moment your sanitizer dips even slightly. This is why so many Georgia pools that look fine through March suddenly turn green in early May: the pollen season loaded the water with phosphates, and the first hot week of spring gave algae everything it needed to explode.

What makes Georgia's pollen particularly brutal for pools is the pine pollen. Oak pollen, which starts earlier in February, is relatively fine and tends to dissolve quickly. Pine pollen is different. Those yellow grains are larger, stickier, and they form a visible coating on the water surface that resists wind action and even light rain. Pine pollen is what turns your pool yellow, and it is what fills your skimmer baskets to the brim overnight.

Your Pollen Season Maintenance Strategy

The good news is that pollen season is predictable and manageable if you adjust your routine proactively rather than reactively. I tell my customers in Marietta and Kennesaw the same thing every February: do not wait until your pool looks yellow to change your approach. Start adjusting your routine in early March, before the pine pollen peaks, and you will stay ahead of it rather than chasing problems.

Here is the seven-step strategy I use on every pool Peachy Pools services during pollen season. This is the same approach I have refined over 15 years and hundreds of pollen seasons across North Georgia.

Chemical Adjustments During Pollen Season

Beyond simply raising your chlorine target, there are several chemical adjustments that make a meaningful difference during pollen season. These are the same tweaks I apply to every pool on the Peachy Pools service route from early March through late April.

Chlorine management: As mentioned, target 3-4 ppm free chlorine instead of the normal 2-3 ppm. If you use a salt chlorine generator, increase the output percentage by 10-20% during pollen season. If you use tablets, add one or two extra tablets to your feeder or floater. Liquid chlorine users should add a supplemental dose midweek between their normal weekly treatments. For a full breakdown of chlorine chemistry, see our guide to ideal pool chlorine levels.

pH monitoring: Pollen tends to be slightly acidic, which can push your pH downward over time. This is actually somewhat helpful since chlorine is more effective at a lower pH, but if your pH drops below 7.2, you need to add soda ash to bring it back up. Test pH at least twice weekly during pollen season. For a comprehensive understanding of all the chemical relationships in your pool, refer to our complete pool water chemistry guide.

Cyanuric acid (stabilizer): Make sure your CYA level is between 30-50 ppm heading into pollen season. CYA protects chlorine from UV degradation, and since you are going to be using more chlorine than usual, you want to make sure the sun is not burning through it faster than pollen is consuming it. Low CYA during pollen season is a recipe for a chlorine crash.

Clarifier: A pool water clarifier can be helpful during pollen season. These products cause tiny suspended particles — including dissolved pollen — to clump together into larger particles that your filter can actually capture. Without a clarifier, some of the finest pollen particles pass right through sand filters and even some cartridge filters. Use a clarifier once per week during peak pollen and you will notice a measurable improvement in water clarity.

The North Georgia Pollen Timeline

One of the advantages of having serviced pools in this area for over 15 years is that I have a very clear mental calendar of what to expect and when. Georgia's pollen season is not one single event — it is a rolling series of different pollen types, each with its own timing and its own impact on pool maintenance.

Late February to mid-March — Tree pollen begins. Cedar, juniper, and maple trees start releasing pollen before most people realize allergy season has started. For pools, this is the warm-up period. You will start to notice a light dusting on the water surface, especially in the morning. This is your signal to begin transitioning from your winter routine to your pollen season routine. Start increasing your pump runtime and checking baskets more frequently.

Mid-March to mid-April — Pine pollen peak. This is the main event. Pine trees in North Georgia — and there are millions of them — release enormous quantities of yellow-green pollen that coats literally everything. In the Canton and Woodstock areas, where homes are heavily surrounded by pine forests, pools can accumulate a visible yellow layer on the surface overnight. Marietta and Kennesaw get hit just as hard, especially in neighborhoods with mature pine canopy. During peak pine pollen weeks, the Atlanta Allergy and Asthma clinic regularly records pollen counts above 1,500 particles per cubic meter of air. Some days exceed 3,000. For perspective, anything above 120 is considered "high."

This two to four week window is when your pool needs the most aggressive attention. Daily skimming is not optional — it is essential. Filter cleaning may need to happen every three to five days. And your chlorine demand will be at its annual peak, rivaling even the hottest weeks of July.

Late April to mid-May — Oak pollen and the transition. Pine pollen tapers off, but oak pollen (which has been present since March) continues, and grass pollen begins ramping up. The yellow coating on your pool will ease, but you should not drop back to your normal routine until early to mid-May. This transition period is when I recommend the phosphate remover treatment mentioned earlier — the pollen has loaded your water with nutrients, and removing them now prevents problems later.

Late May through June — Grass pollen. By this point, the heavy pollen deposits have stopped, but grass pollen remains elevated through early summer. This pollen is finer and less visible than pine pollen, so many pool owners think pollen season is over. It is not — but the maintenance impact drops significantly. You can generally return to your normal summer routine by late May, with the higher pump runtime carrying over into summer heat management.

When to Increase Your Cleaning Frequency

Not every week during pollen season is equally intense. Some years, a late cold snap in March delays the pine pollen release and compresses the entire season into three brutal weeks instead of spreading it across six. Other years, a warm February triggers early pollen release and extends the season on both ends. The key is to watch your pool and your baskets, not the calendar.

Increase your cleaning frequency any time your skimmer basket fills up within 24 hours, the pool surface develops a visible pollen film between cleanings, your filter pressure rises more than 5 PSI in less than a week, or your free chlorine drops more than 1 ppm in 24 hours without heavy swimmer use. Any one of these signals means pollen is outpacing your current maintenance rhythm and adjustments are needed.

Why Georgia Pollen Is Different From Other States

I have talked to pool service professionals from other states, and they are always surprised when I describe what Georgia pollen season looks like for pool maintenance. States like California and Arizona have pollen seasons, but they do not have the density of pine forests that Georgia has. Northeastern states have pine trees but shorter, less intense pollen seasons because their springs are cooler.

Georgia sits in a uniquely difficult position: we have massive pine forests (Georgia is called the Peach State, but it could just as easily be the Pine State — loblolly and shortleaf pines cover over 12 million acres), warm springs that trigger aggressive pollen production, and the humid conditions that keep pollen suspended in the air longer. Add in the fact that most Georgia homes do not winterize their pools — meaning the pool is sitting there, open and exposed, when pollen season hits — and you have a maintenance scenario that is genuinely unique to this region.

In the specific areas Peachy Pools serves — Canton, Woodstock, Kennesaw, Marietta, Acworth, Dallas, and the surrounding communities — many neighborhoods were built among existing pine stands. It is common for a backyard pool in Cherokee County to have 15 or 20 mature pine trees within 50 yards. That kind of tree density means pollen production is not just ambient from the broader environment — it is raining directly down from above. These pools need the most aggressive pollen season management of any I service.

When to Call a Professional

Many pool owners successfully manage pollen season on their own with the strategies outlined above. But there are situations where calling in professional help is the smarter move.

If your pool has already turned green or cloudy despite your efforts, if you have been fighting low chlorine for more than a week, if your filter pressure will not come down even after cleaning, or if you simply do not have time to skim and test daily during the busiest pollen weeks — those are all situations where a professional service visit can save you time, money, and frustration.

Pollen season problems that go unaddressed have a way of compounding. The pollen feeds algae, the algae clogs the filter, the clogged filter reduces circulation, and reduced circulation creates dead spots where more algae grows. By the time you realize you are losing the battle, you might need a full pool recovery instead of a simple maintenance adjustment.

Peachy Pools serves homeowners across Cobb, Paulding, and Cherokee counties with weekly pool service that includes pollen season adjustments at no additional charge. During March and April, our service visits automatically include extra skimming, basket cleaning, filter checks, and the chemical adjustments described in this guide. If your pool needs a one-time pollen season cleanup, we offer that too.
