When you picture your pool, do you see crisp, clear water or green streaks and cloudy patches? If algae have taken hold, it won’t just make your pool look unpleasant. Left unchecked, algae can spread quickly and even affect your health.
At Royal Pool & Spa, we’ve helped countless Twin Cities homeowners keep algae at bay. Let’s look at why algae are a problem, the most common causes, and what you can do to prevent them from taking over your backyard pool.
Why Algae Are More Than Just an Eyesore
It’s tempting to think algae are harmless, but that’s not the case. Swimming in an algae-filled pool can lead to uncomfortable or even serious health concerns, including:
- Skin irritation and rashes
- Eye, nose, or throat discomfort
- Breathing problems
- Headaches
- Upset stomach, nausea, or diarrhea
The good news: with proper pool care, algae doesn’t stand a chance.
3 Common Causes of Pool Algae
1. Wind and Weather
Algae spores are everywhere outdoors. Wind and rain carry them into your pool; even a light drizzle can introduce thousands of spores. While a pool cover or enclosure reduces debris, it won’t completely stop algae from finding their way in.
Solution: Stick to a regular maintenance schedule. Balanced sanitization and pH levels will kill spores before they multiply.
2. Improper Water Chemistry
Water that’s too acidic or too alkaline makes it easy for algae to thrive. The sweet spot for pool water is a pH between 7.4 and 7.6. That range keeps sanitizers working effectively and helps prevent organic growth.
Solution: Test and balance your water consistently. If you’re unsure how to get it right, a professional pool service can take the guesswork out of the process.
3. Pool Equipment Issues
If your filter, pump, or chlorinator isn’t working as it should, your water may become stagnant and perfect conditions for algae blooms. Common equipment problems include:
- A filter that’s too small or damaged
- An overheating pump
- Air or water leaks in the system
- Clogged or broken pump impellers
- Faulty chlorinators or valves
Solution: Don’t wait for repairs. A trained technician can quickly identify the problem and keep your pool equipment running efficiently.
