Maintenance Guide

Pool maintenance starts with pool circulation because if your pool water isn’t moving, your pump isn’t pumping, or your filter isn’t filtering, you’re going to be fighting an uphill battle to keep your pool clean. This is because stagnant water is a breeding ground for algae growth.

            There are several parts that make up your pool’s circulatory system. The skimmer, the pump, the filter, and the jets. If any one of these pieces is significantly impeded, your water quality will suffer. Here’s a short explanation of how a pool works to keep your water clean and circulating:

            The pump sucks water from the pool through a skimmer (usually a rectangular door)

Water travels through the pump into the filter

The filter cleans out particles that are making your water dirty

Water is pushed back into the pool through pool jets

            Your pool pump is kind of like the “heart” of your swimming pool. The pump draws water through the filtration system, where it’s stripped of dirt, debris, and other impurities. From there, the clean water goes back to the pool.

Duration: 8-12 hours per day

In other words, the more you run your filtration system, the cleaner your water will be – and the less time you’ll have to spend scrubbing algae or balancing your water. If running your filter 24/7 isn’t realistic, aim to run your pool filter 10 to 12 hours per day. If you are in a warmer climate, you should run your pump a little more per day. This is why we suggest investing in a variable speed pool pump because they can run at a lower speed throughout the day, which saves money, and energy, and makes less noise.

Backwash or Clean the Filter if Necessary

Frequency: When the filter gauge reads about 10 psi higher than normal   

If your pump gauge is about 10 lbs or more above the normal reading (usually 10-15 psi for a clean filter), then it may be time to backwash your filter. If you are using a cartridge filter, then you will need to clean your filter cartridge.

Frequency: 1-2 times per week

Cleaning the skimmer and pump baskets regularly is important to the overall maintenance of your swimming pool. Clogged baskets make your pump work harder to try to cycle the water. This can decrease the life and stress the seals in your pump. Additionally, critters like frogs can get stuck in your skimmer, so you will want to make sure those are removed in a timely manner as well. We suggest cleaning your skimmer once or twice a week depending on how often you use it.

To clean the skimmer basket, simply turn off your pool pump and empty the removable basket under the skimmer lid, then replace it.

Every once in a while, you should also clean out the pump basket on your pool pump. You don’t have to do this as often since the skimmer catches most of the debris.

Another easy adjustment to make is to make sure your pool jets are pointing away from your skimmer so that your water cycles in a circle. This will encourage the pool water to rotate and make it easier for your skimmer to get rid of debris. It also helps to angle the jets downward so that the bottom of the pool gets circulation as well. If there are any parts of the pool that struggle to get water, most commonly around the steps, ladders, crevices, and corners of your pool, you can angle towards these areas too.

Frequency: Vacuum once a week. Brush and Skim once per day.

The next step in the trifecta of pool maintenance is cleaning which comprises brushing your pool, skimming the debris off the top, and vacuuming the pool. Manual maintenance is a normal part of pool ownership unless you own a robotic pool cleaner that will do it for you.

Scrubbing the walls with a pool brush pool prevents algae, staining, and scaling, especially around “dead areas” such as steps, ladders, crevices, and below the skimmer.

Skimming the surface of the water with a net or leaf rake removes large debris. This debris is unattractive to swimmers and can fall to the bottom of your pool where it can leave stains.

Vacuuming your pool is another essential part of removing debris that can reduce circulation and damage your pool. You can use a vacuum head, hose, and pole attached to your skimmer through a vacuum plate.

Frequency: Test 1-2 times per week. Shock Bi-Weekly.

Chemistry is another huge factor in keeping your water clean. When your water is properly balanced, you’re less likely to struggle with issues like cloudy water, green water, or the buildup of harmful bacteria. That’s why a good testing kit is essential for your pool maintenance toolkit.

For best results, test your water weekly. To keep things easy, opt for a test kit that will tell you if you need to add pool chemicals to maintain your water balance. Most pool supply stores and big-box retailers sell easy-to-use test kits or test strips that allow you to test your swimming pool water for the key chemicals. Here are the essential ranges to keep in mind:

pH: Ideally, you want your pool water to have a pH of around 7.5. This is important because pH levels that are too high or too low can lead to a variety of pool maintenance issues, from equipment corrosion to increased green algae growth. See our pH guide
Calcium hardness: Again, it’s all about balance here: Shoot for 200 – 400 ppm in a pool. When calcium hardness levels are too low, you risk damage to your pool’s plaster finish or vinyl liner. But if your pool’s calcium hardness is too high, you’ll be scraping away tough-to-remove calcium deposits. See our calcium hardness guide
Alkalinity: You want to aim for total alkalinity of around 120 to 150 ppm. If it’s below this range, your pool’s pH can be affected, and your pool’s surfaces are more prone to stains. If it’s on the higher side, your water can become cloudy. See our alkalinity guide
Chlorine: Available in sticks, granules, and tablets, chlorine breaks down harmful bacteria and sanitizes your pool water. You’ll want to keep the chlorine levels stable to ensure that your pool stays clean. See our chlorine guide
Phosphates: If your pool water is green and cloudy, it is possible that the phosphate levels in your pool are too high. Having too many phosphates in your pool can make algae growth more likely and makes it more difficult to maintain proper pool chemistry. See our phosphates guide.

Maintaining Optimal Calcium Hardness for a Healthy Swimming Pool

To ensure a healthy and well-maintained swimming pool, balancing the pool water is essential, and calcium hardness plays a critical role in this process. Calcium hardness measures the concentration of calcium ions in the water, which is crucial for preventing issues related to both corrosion and scaling.

The Impact of Calcium Hardness

When calcium hardness levels drop too low, the water becomes aggressive and seeks to stabilize itself by extracting calcium from pool surfaces. This can lead to problems such as etching, pitting, and corrosion, potentially damaging the pool’s structure, equipment, and plumbing over time. Conversely, excessive calcium hardness can cause scaling, resulting in unsightly white deposits on pool surfaces, plumbing fixtures, and equipment.

Optimal Calcium Hardness Levels

To maintain a well-balanced pool, it is recommended to keep calcium hardness within the range of 200-400 parts per million (ppm). However, this ideal range may vary based on factors such as the type of pool surface, the quality of the water source, and local climate conditions.

Regular Testing and Maintenance

Regular testing of calcium hardness levels is essential for ensuring they remain within the recommended range. Using test kits or digital meters designed specifically for pool water analysis can provide accurate measurements. By keeping calcium hardness levels in check, you help extend the lifespan of your pool and ensure a safe, enjoyable swimming experience for everyone.

Maintaining proper calcium hardness is a crucial aspect of overall pool water balance and should not be neglected.

In addition to keeping your pool chemistry balanced, it’s also a good idea to shock your pool once every week or two. “Shocking” means you overload your water with sanitizer to kill off any bacteria, contaminants, and organic matter.

In general, the more you use your pool, the more often you should shock. You may also want to shock your pool after periods of heavy use or weathering in these cases:

After an intense storm
After a spill or unexpected contamination
After an algae breakout

To maintain a saltwater pool you’ll need to keep your filter, pump, and skimmer clean and in good operating condition. With saltwater pools, you must inspect the salt chlorinator cell and replace it when needed. Test regularly for proper water chemistry to maintain clean, clear pool water.
