Don’t wait – get in touch today to see how we can help you keep your pool clean.

Swimming pool filtration

Swimming pool filtration is an important part of keeping you and your family safe from swimming-borne contaminants. Filtration works by trapping particles, running water through a filter, flocculation (mixing with a coagulant), or using ion exchange or a combination of all three to reduce the number of particles in the pool water. This helps protect your pool water from bacteria, algae, and other impurities that can make it unsafe to swim in.

The most common type of filtration used for swimming pools is sand filtration. Sand filter systems work by allowing water to pass through the media bed where particles are trapped. Sand filters come in a variety of shapes and sizes and contain different levels of abrasive grits for capturing larger or smaller size particles. These filters need regular backwashing to keep them clean, as built-up debris can lead to clogged filters and ineffective filtration.

Cartridge filter systems can also be used for swimming pools. A cartridge filter system works much like sand filters but instead uses cartridges made from spun or pleated fabrics as the filter media that captures any sediment or debris in the pool water. Cartridge filters need regular backwashing but use less energy than sand filters making them ideal for small above ground pools.

Finally, DE (diatomaceous earth) filters are becoming more popular due to their efficient removing capabilities and minimal maintenance requirements. A DE filter uses diatomaceous earth powder (also called diatomite) as its filtering media which is effective at trapping tiny organic particles and microscopic organisms that other filters are not able to capture while also requiring less attention than either sand or cartridge filters.

Sanitization for swimming pools

Water sanitization is key to maintaining safe, clean and healthy swimming pool water. While there are several aspects that help keep your pool clean, the primary factor is maintaining proper sanitization levels. When the appropriate amount of sanitizer is used in combination with circulation and filtration, it ensures that your pool water remains free from algae, bacteria and other contaminants.

While chlorine is the most common form of swimming pool sanitizer, there are other options available such as bromine, ozone and saltwater chlorinators. While each type of sanitization has its own benefits, some will work better than others given certain factors such as the size of your pool or your budget.

Sanitizing agents should be applied regularly to maintain a residual level in the water that will prevent bacteria and algae growth while allowing swimmers to enjoy their time in the water without experiencing any irritation or health risks valid due to microbial contamination. Additionally, it’s important to test the pH level daily and make adjustments as needed so that all chemicals remain balanced for optimal performance.

pH level in swimming pool water

Maintaining the pH level in your swimming pool water is essential for keeping it safe and inviting. The level of acidity or alkalinity, also known as the pH level, should remain within a range of 7.2 to 7.8. If the level is too low or too high, not only will your pool become uncomfortable and perhaps even unsafe for swimming, but it can also damage the interior finish of your pool, such as the tiles and grout.

The importance of keeping your swimming pool’s pH level balanced lies in ensuring that it remains at a safe range – consistent with what’s recommended by health officials – to prevent any potential skin irritation or infection while swimming in it. Acidic water can cause eye irritation, dry hair, itchy skin and more serious reactions including sore throats or respiratory issues. Similarly, alkaline levels can cause scaling on fixture surfaces corrode metal fixtures, affecting other materials like solar blankets that may fall into disrepair over time due to its effect on plasticizers used in their construction.

Depending on location and climate conditions, there could be fluctuations in its pH level due to naturally occurring substances like rainwater or evaporation which could affect its alkalinity and/or acidity levels. Therefore; it’s important to test your pool with a water testing kit periodically so you know if balance needs adjusting; test strips are available online and chemists for this purpose which would help you diagnose problems before they arise or worsen further down the line. Different chemicals are required depending on whether acidity or alkalinity levels need balancing; be sure to check manufacturer directions when adding them into pools so as not to throw off their chemical concentrations levels further too!

Total alkalinity and swimming pools

Total alkalinity is important for maintaining water balance in swimming pools and is often confused with pH. Total alkalinity, expressed in parts per million (ppm), refers to the concentration of buffers in pool water that resists sudden changes in pH levels as chemicals such as chlorine or acid react. A pool with low total alkalinity can cause sudden, drastic fluctuations in pH which causes staining, scaling and other damage to the pool surface.

The ideal range for total alkalinity should be between 80-120 ppm. If the total alkalinity level is outside of this range then an adjustment should be made to bring it back into balance. An acid or base can be introduced into the pool water to adjust levels and a test kit should always be used to measure before and after adding any chemistry product.

Total alkalinity can also affect a pool’s pH level if it’s too high and has a pH above 7.8 causing irritation to swimmers and making chlorine molecules less effective against bacteria growth due to altered chlorine demand curves. Conversely, low levels of alkalinity may cause high amounts of acidity that breaks down surfaces of your fixtures or game playing equipment found within the pool environment.

Making sure that your total alkalinity levels are within range is essential for having a healthy swimming pool environment where bathers enjoy disease free waters at safe pH levels that won’t damage equipment within your facility. Establishing consistent maintenance practices including testing at least 2–3 times weekly can keep you informed on chemical balance during peak swim season so you don’t run into problems unexpectedly down the road.

Calcium hardness in swimming pool water

Calcium hardness is one of the most important elements to test when it comes to monitoring the quality of your swimming pool water. If you find that your swimming pool has high calcium levels, it can cause staining, cloudy water, and scale build up on surfaces and equipment. Maintaining proper calcium hardness in a swimming pool can help ensure that your equipment is not damaged, and that your water remains safe for swimming.

Calcium hardness levels should generally be between 200 – 400 ppm (parts per million). A pool with too much calcium will typically have a white coating on its walls or feel slippery on its surfaces. To lower the calcium levels in your pool, you may need to add acids such as muriatic acid or sodium bisulfate. Adding additional algaecide or chlorine could also increase the effectiveness of other treatments. Additionally, you could use a reverse osmosis system for pools to remove excess levels of dissolved minerals from the water. This will reduce mineral buildup and allow for better control over pH levels in your swimming pool.

It is important to note that it may take several treatments over an extended period of time to bring high calcium hardness levels down. Additionally, you may need more than one type of treatment if there are other issues impacting the quality of your water such as:

  • Clay particles
  • Organic matter like sweat or oil from swimmers bodies.

Regularly testing your water on a weekly basis can help you catch any changes early – so be sure to stay diligent!


In conclusion, it is important to keep your swimming pool in good condition, and water quality is a big part of that process. Maintaining a consistent, proper level of chlorine and pH balance can help ensure that you and your family can safely enjoy your pool. Test the water weekly if possible, as this will help to ensure that you are not only meeting the standards for swimming pool use but also keeping your family safe from any possible contaminants or chemicals in the water.

Additionally, be mindful of proper cleaning techniques for both the filter system and the actual pool surface which can help keep bacteria away from the area. These proactive steps should help you to enjoy clean, quality water in your swimming pool for many seasons to come.
