How Rain Affects Pool Chemistry in Brevard County, FL

Brevard County has been dealing with plenty of September heat, humidity, showers, and thunderstorms. Recent National Weather Service forecasts for the

Melbourne/Brevard area have continued to show temperatures around the upper 80s to low 90s along with recurring showers and storms—exactly the combination that can make pool chemistry difficult to maintain.

So this week's tip is about something we're seeing firsthand: what all that rain can do to your swimming pool.

Rainwater Isn't Free Pool Water

When we get repeated heavy rain, your pool can fill up quickly. Unfortunately, that extra water doesn't arrive properly balanced and sanitized.

Rain can dilute the chemicals already in the pool. Meanwhile, Florida heat, sunlight, organic debris, and swimmers continue putting demands on your sanitizer.

The result? A pool that looked beautiful a few days ago can suddenly become cloudy or develop algae.

That's one reason simply looking at the water isn't enough.

Don't Automatically Dump Chlorine Into It

After several days of rain, homeowners sometimes see their chlorine reading drop and immediately start adding chemicals.

But chlorine is only part of the equation.

The pool's pH, alkalinity, stabilizer, sanitizer level, circulation, filtration, and overall water balance all work together. Adding chemicals without testing first can create another problem while you're trying to solve the first one.

Test first. Treat second.

Watch Your Water Level, Too

After a major rain event, check the pool's water level.

If it gets too high, the skimmer may not operate as effectively as it normally does. But don't randomly drain large amounts of water from a pool either. If you're unsure what needs to be done, call a professional.

This Week's Pool Tip

After several days of rain, don't assume clear water means balanced water.

Have the chemistry checked, make sure circulation is strong, empty overloaded baskets, and watch for the first signs of cloudiness or algae.

This is also why consistent weekly pool service matters. At Premier Coastal Pool Services, we're not just trying to make the pool look good on service day. We're

watching chemistry, circulation, filtration, equipment, and changing conditions from week to week.

If you're in Brevard County and your pool keeps going from beautiful blue to "Why is there a swamp in my backyard?", give us a call.

Your Pool Filter: The Hardest-Working Employee Nobody Thinks About!

October 27, 2026

Here's something every Brevard County pool owner should know: You can have perfectly balanced chemicals and STILL have a cloudy swimming pool! How is that possible? Simple. Your pool filter might not be doing its job! Think about it. Your filter works day after day, trapping dirt, pollen, leaves, dead algae, and all the other unwanted visitors that find their way into your swimming pool. And here in Brevard County, Mother Nature certainly knows how to keep our filters busy! With October bringing changing weather patterns, gusty winds, and occasional storms, your filtration system can face some serious challenges. What Does Your Pool Filter Actually Do? Your pool filter has one primary responsibility: remove unwanted particles from the water as it circulates through the system. While chlorine helps sanitize your pool, the filter physically removes suspended debris. They work together. Without adequate filtration, your swimming pool can become cloudy, circulation can suffer, and maintaining proper water quality becomes more difficult. It's like washing your dishes with dirty water. Eventually, something's going to look pretty nasty! Five Warning Signs Your Filter Needs Attention Your pool water looks cloudy. If your chemicals are properly balanced but the water remains cloudy, poor filtration could be contributing to the problem. Your filter pressure is unusually high. As filters collect dirt and debris, resistance to water flow increases. A common guideline is to clean the filter when pressure rises approximately 8–10 PSI above its normal clean operating pressure, although manufacturer recommendations vary. Water circulation seems weaker than normal. If your return jets aren't pushing water as strongly as they usually do, something may be restricting circulation. This could involve the filter, skimmer baskets, pump basket, or another equipment issue. Your filter cartridges are deteriorating. Over time, cartridge pleats can become damaged, flattened, or difficult to clean. Eventually, replacement becomes necessary. Your pool keeps getting dirty unusually quickly. If debris remains suspended or water clarity doesn't improve after proper cleaning and chemical treatment, your filtration system deserves a closer look. Here's Something Many Homeowners Don't Realize A dirty filter doesn't necessarily mean you need a new filter. Sometimes a thorough cleaning is all that's required. However, cleaning a damaged or worn-out cartridge won't restore its original performance. That's why regular inspection matters. At Premier Coastal Pool Services, we routinely clean filters approximately every three to four weeks as part of our maintenance program, adjusting when conditions require additional attention. We also inspect pool equipment during weekly service. This Week's Pool Tip Take a look at your pool's filter pressure gauge! When your filter has just been cleaned, record its normal pressure reading with the pump operating at its usual speed. Check it periodically. If the pressure rises significantly above that baseline, it's time to investigate. Also, after windy weather, check your skimmer and pump baskets for accumulated debris. Important: Always shut off the pump before servicing equipment, and never open a pressurized filter tank. Follow the manufacturer's pressure-release instructions or have a qualified professional handle the work. Why Professional Weekly Maintenance Matters At Premier Coastal Pool Services, we don't believe maintaining a swimming pool means simply throwing chemicals into the water and hoping for the best. Our regular service includes: Weekly brushing, skimming, and vacuuming. Water testing and chemical balancing. Routine filter cleaning and inspection. Weekly equipment inspections. Monitoring water circulation and filtration. Phosphate treatment and other necessary water chemistry adjustments. Our goal is simple: Keep your pool clean, clear, properly balanced, and ready whenever you are! KNOW SOMEONE WITH A CLOUDY POOL? If you know a Brevard County homeowner who's constantly fighting cloudy water, weak circulation, or recurring filtration problems, we'd appreciate an introduction.
