Q&A With a Pool Pro: 10 Common Pool Questions Answered by a Pool Expert

Pool ownership comes with a lot of questions, from water chemistry and filtration to algae and equipment issues.

To help answer some of the most common ones, we sat down with Chad Chicoine, Pool Scouts Franchise Technical Coach with more than 20 years of experience in the pool industry. Here are his answers to the questions pool owners ask most often.

How often should I have my pool professionally cleaned?

For most pools, weekly service is the best starting point. Some pools can go longer depending on usage, nearby trees, weather, and the equipment setup, but weekly service helps keep small problems from turning into bigger ones.

Why does my pool keep turning green?

Most of the time, it comes down to low sanitizer levels, poor circulation, not brushing enough, or the pool falling behind after heavy use or bad weather. A green pool usually is not caused by one single thing. It is typically chemistry, filtration, and circulation not keeping up together.

How often should I test my pool water, and what should I actually be testing for?

During the season, homeowners should test their pool water at least a couple of times a week, and more often during heavy use, hot weather, rain, or if the pool is having issues.

Chlorine and pH are the big ones most people know, but they are not the whole story. Alkalinity, stabilizer, calcium hardness, and other factors all play a role in how the water behaves and how well the chlorine works.

How long should I run my pool pump?

Most pools need the pump running long enough each day to properly circulate and filter the water. A lot of pools fall somewhere around 8 to 12 hours during the season, but it depends on the size of the pool, the equipment, the temperature, and how much the pool is being used.

The goal is not just running the pump for a random number of hours. The goal is making sure the water is moving, filtering, and staying consistent.

Why is my pool water cloudy?

Cloudy water usually means the pool is not filtering well, the chemistry is off, or there is something in the water the system is trying to catch up with.

It can be caused by high pH, low chlorine, dirty filters, poor circulation, or early algae growth before the water turns green.

What’s the most common mistake pool owners make? 

The  most common mistake is waiting too long to deal with small issues.

Low water level, unusual equipment noises, poor flow, rising filter pressure, cloudy water, algae starting to form, or minor staining can all turn into larger problems if they are ignored.

Pools usually give warning signs before something becomes expensive. The key is catching those signs early instead of waiting until the pool is green, the equipment stops working, or the water becomes much harder to recover.

Can I maintain my pool myself?

Yes, some homeowners can. You just need to be consistent and understand that pool care is about more than adding chlorine once in a while.

You have to test the water, brush and clean the pool, maintain the filter, check the equipment, and know when something does not look right.

What signs tell you my pool needs professional attention?

If the water keeps turning green or cloudy, the pool is losing water, the equipment is noisy, the pump will not stay primed, the filter pressure is unusual, or you are constantly adding chemicals without seeing improvement, it is probably time to have someone take a look.

How do I know if my pool filter is doing its job?

A good filter should help keep the water clear, but you also need to watch the pressure, flow, and how the pool looks over time.

If the pressure is too high, the filter may need to be cleaned. If the pressure is too low, there may be a flow issue. If the water stays cloudy even though the chemistry looks decent, the filter may not be keeping up.

Filters are easy to overlook, but they play a major role in whether a pool stays clean.

Why does my pool lose chlorine so quickly?

Chlorine can get used up quickly from sunlight, heat, heavy pool use, rain, debris, algae, or poor water balance.

Sometimes homeowners keep adding chlorine, but the pool is burning through it because something else is driving up the demand. That is why testing the full water balance matters. If you only look at the chlorine level, you may miss the real reason it is not holding.

What should I do to my pool after heavy rain or bad weather?

After heavy rain or bad weather, the first step is to clean out debris, empty baskets, check the water level, and test the water before making major chemical adjustments.

Rain can dilute the pool, affect pH, bring in debris, and increase sanitizer demand. It is also a good time to brush the pool and make sure the system is circulating properly.

Keeping Your Pool in Great Shape

As Chad points out, many pool problems start small. Cloudy water, algae, equipment issues, and water balance concerns are often easier to fix when they are caught early.

The best thing pool owners can do is stay consistent with testing, cleaning, and routine maintenance. Paying attention to changes in your pool can help prevent bigger problems and keep your water clean, safe, and ready to enjoy.

Whether you maintain your pool yourself or work with a professional, understanding the basics goes a long way. And when questions come up, the Pool Scouts team is always here to help.
