Summer’s here, the days are longer and you can practically hear the pool calling your name. There’s nothing better than sunny days, cool water and floating the afternoon away.
But before you jump in, it’s normal to have a few pool care questions on your mind. Don’t stress, we’re here to give you answers.
We’ve rounded up the most common (and a few you might not have thought to ask) questions about pool care and our simple answers to get your summer off to a splashing start. Let’s go!
Q: When should I open my pool for the season?
It’s better to open your pool earlier rather than later. It’s not about the month; it’s about the temperature for the region you’re located in.
It’s best to open your pool before your water temperature reaches 60ºF. Or open it when the outside daytime temperature stays consistently above 70ºF.
Why?
When the pool is closed, the water is stagnant since the pump isn’t operating. And, when the water temperature rises above 60ºF, algae growth is set into motion. Don’t give it a chance! Open your pool even if you don’t plan to use it; it’s easier to maintain it once it’s opened than when it’s stagnant.

Q: What is the most important part of pool care?
Great question! It’s water balance. Balanced water is the key to consistently clean, clear water.
Balanced water means that the chemical levels in your pool are in harmony; in other words, the water’s chemical levels are in the ideal ranges.
To maintain balanced water, focus on keeping the top three chemistry levels within their ideal ranges.
Alcalinidad total: 80 – 120 ppm
pH: 7.2 – 7.8
Total Hardness: 200 – 400 ppm

Q: How do I keep my pool clean?
In addition to maintaining water balance, sanitizer levels are essential to keeping pool water clean and clear. You must have enough chlorine in the water to kill bacteria and viruses; the industry standard for an all-chlorine pool is 1.0 ppm – 4.0 ppm.
Too much chlorine is irritating to skin, eyes, hair, bleaches swimsuits and can damage surfaces. Too little chlorine won’t adequately kill bacteria and viruses, making water not safe to swim in.

The result is a more enjoyable swimming experience — from the first splash to the last — so you can spend less time managing your pool and more time enjoying it.
Q: How often should I test my pool water?
Water testing is the foundation of proper pool maintenance. Why? Because it keeps you in the know on how your pool water is doing. Testing your water regularly allows you to monitor the key factors we mentioned above: Chlorine, Total Alkalinity, pH and Total Hardness.
If you use FROG® Products, you should test your pool at least once a week. If you don’t use FROG, it’s best to test at least twice a week. For all pools, it’s important to also test after storms, heavy use or when you top off the pool with fresh water.
Q: How often should I shock my pool?
Weekly shocking is typically recommended for all pools! In addition, it’s smart to shock again after heavy use or rain. Be sure to follow the manufacturer’s directions for use.
Q: How often should I run my pool pump?
Your pool pump circulates and filters pool water. Running the pump for an adequate amount of time each day – we recommend at least 8 hours – is essential to ensure the water is properly circulated and filtered, preventing algae and bacteria growth.
All the water in your pool must run through this filtration process at least once a day to keep your pool clean, clear and ready for action.
Aim to run your pool’s pump for at least 8 to 12 hours of circulation per day, adjusting as needed based on the size of your pool and the climate in your area!
Q: How often should I brush my pool?
Every week! It makes a big difference in making sure your pool is always ready to jump into. Be sure to brush all the surfaces of your pool – the walls, floors and steps if you have them – it goes a long way to prevent algae and clean out debris.
Water Care Expert Tip: Always brush the floor from the shallow end toward the drain in the deep end. All debris collected while brushing should be pushed toward the main drain, where it will go to the filter.
Q: How often should I clean my pool filter?
Your pool filter is one of the unsung heroes of pool care. It works behind the scenes to keep your water clean and clear. Regular filter maintenance isn’t just a good habit — it’s essential for water care and the longevity of your equipment.
The frequency of cleaning your pool filter depends on the type of filter you have and how often you use your pool — but as a general rule, you should clean your filter about once a month.
A couple of signs will also let you know when it’s time for a cleaning:
- Your filter pressure gauge rises 10 psi above normal
- Your pool water starts to look cloudy
- There’s weak flow from the return jet(s)
Q: How do I clean my pool filter?
The method you’ll use to clean your pool filter depends on your filter type. The three most common kinds of pool filters are cartridge, sand and diatomaceous earth (D.E.) filters.
Quick Pool Filter Cleaning Tips:
- Never use a pressure washer – it can damage delicate filter materials
- Avoid bleach for cleaning filters, especially cartridges, as it weakens the fibers
- Monitor your filter pressure gauge regularly to stay ahead of maintenance needs
Q: How do I get rid of pool algae?
Algae can happen to anyone! The key is to act fast when you notice any signs of algae.
To get rid of pool algae, start by running your pool pump 24 hours a day to promote water circulation and distribute chemicals evenly. Then shock the pool with chlorine to raise free chlorine levels to at least 2-4 ppm and add an algaecide. This will help kill existing algae and prevent further growth.
For an algaecide, we recommend RANA® Algas eliminadas®. It’s easy, powerful and effective. Plus, it can be used in any pool with a skimmer – even if you don’t use FROG Products already. FROG Algae Gone comes in a prefilled Pod and cures algae outbreaks fast.
Water Care Expert Tip: Algae presence in your pool water means fluctuations in pH, so be sure your pool’s pH is between 7.2 and 7.8.
During this process, brush your pool surfaces at least twice a day to break up algae’s protective barrier. After you brush, be sure to vacuum to remove dead algae and debris, then clean or backwash the pool filter afterward to maintain good water flow and filtration. Continue this cycle until the water is clear!

Q: How can I avoid pool algae?
The best way to prevent algae in your pool is by sticking to a consistent, simple maintenance routine. Keep your water’s pH between 7.2 and 7.8, and ensure chlorine stays within the recommended range — 1 – 3 ppm for standard chlorine pools or 0.5 – 1.0 ppm with mineral systems like FROG. Balanced water keeps algae at bay and helps your pool chemicals work effectively.
Clean or backwash your filter regularly to remove debris and organic matter, which algae feed on. Skim leaves, bugs and other debris as soon as you notice it, and if possible, use a pool cover when your pool isn’t in use.
For extra protection, use an algae preventive treatment like RANA® Barrera contra algas de 90 días®. It’s easy-to-use and prevents algae growth for 90 Days. FROG 90-Day Algae Barrier goes to work fast and comes in a prefilled Pod. Just drop it into your pool’s skimmer basket!
Q: How do I fix cloudy pool water?
To fix cloudy pool water, start with water balance. Make sure Total Alkalinity, pH and Total Hardness are within their ideal ranges. Test and use adjustment chemicals as needed.
Low chlorine levels are a common cause of cloudiness, so shock the pool to quickly raise chlorine and sanitizer levels. Follow the manufacturer’s instructions for the correct dosage amount based on your pool size. Also, check that your pool filter is clean and working properly, as dirty or broken filters worsen water clarity.
Finally, increase your pump’s run time — ideally 24 hours a day until the water clears — to help circulate and filter the water. Vacuum debris from the pool floor and, if cloudiness persists, consider using a pool clarifier to gather tiny particles for easier filtration. With consistent care, your pool will be clear and inviting again in no time.

Q: How can I prevent cloudy pool water?
A crystal clear pool is the result of consistent maintenance and balanced water chemistry. It’s also the key to preventing cloudy water. Here’s how to start a reliable pool maintenance routine:
- Check your pump basket, skimmer basket and filter once a week to clear out debris and blockages. An efficient filtration system helps keep water clear
- Run your pump at least 8 hours a day. This is especially important during hot weather where algae and cloudiness thrive. If your pool is repeatedly getting cloudy, increase your pump time
- Shock your pool regularly – every week is best. Shock extra after heavy use or rainstorms. Shocking helps eliminate contaminants in the water that your regular sanitizer, chlorine, might miss
- Test your water weekly and keep the key water chemistry levels within these ranges:
- Alcalinidad total: 80 – 120 ppm
- pH: 7.2 – 7.8
- Total Hardness: 200 – 400 ppm
- Free Chlorine with Minerals (like FROG): 0.5 – 1.0 ppm
- Free Chlorine without Minerals: 2.0 – 4.0 ppm

When should I close my pool for the season?
It’s best to close your pool when the outdoor temperature is consistently between 50◦F – 60◦F and your pool water temperature is consistently below 65◦F.
Cooler temperatures help prevent algae and bacteria growth.
Did you know there is such a thing as closing your pool too early? Many people see Labor Day weekend as pool closing weekend.
However, this may be too early in certain climates. If you close your pool too early, you may invite algae growth.
According to the Environmental Protection Agency, EPA, warmer water is easier for small organisms to move through and allows algae to float to the surface faster. Water temperatures in the 85◦F range give algae and bacteria an invitation to curl up in a corner of the pool and begin growing.
If temperatures warm up to 65◦F and higher for a day or longer, algae can use up your winter chemicals early and start to accumulate.
But don’t wait too late to close your pool either – autumn temperatures can take a sudden dip below 32◦F, potentially causing expensive damage. Find the right time for your climate – and don’t hesitate to reach out to your local dealer for advice!
