Pumps, Filters, Chlorinators

Pool filtration equipment is used to filter out harmful materials from the pool water, circulate chemicals such as chlorine AND convert salt to useful chlorine. Without efficient circulation, chemicals hardly have a chance !



How does a chlorinator work?
  • Water from the pool containing salt (sodium chloride) enters the cell

  • Electric charge is applied to electrolytic plates and turns chloride ions into chlorine gas

  • Chlorine gas dissolves into the water

  • Water with pure chlorine is returned into your pool


Advantages of a Salt Pool

  • There are many advantages to using a Salt Chlorinator over more traditional sanitizers. For instance, using a salt system gives you extra time for enjoying your pool rather than fussing with water chemistry every day. After you add your first batch of salt, you shouldn’t have to add more salt for at least three months (Don’t forget to test your water!). In addition to that, you shouldn’t have to replace your salt cell for 3-5 years. Using salt makes your pool water feel smoother, look cleaner, and lessens skin and eye irritation. Being an alternative sanitizer, salt chlorine generators reduce the usage of chemicals and waste and are better for the environment. And to top it all off, the overall savings make these low maintenance and eco-friendly products well worth the investment.

  • The most important factor for any pool water pump is not how much it costs to buy or how much it's going to cost to run, but how efficiently it's going to turn over your water. The size of your pump is largely determined by the size of your pool and the amount of water required to turn overr. There are many choices available to us today, so ask the questions and get value for your money.

  • Without efficient circulation, neither your filter, chlorinator nor your automatic cleaner can work to maximum potential. 

  • Circulation is often key to most problem pools !

Cartridge vs Sand Filter

Coaggulants / Floculants / Clarifiers are not recommended unless you remove the filter.

When it comes to pool filters, understanding the differences between sand filters and cartridge filters is crucial. Sand filters, known for their user-friendly operation, use specially designed  pool filter sand or glass to remove dirt and debris from your pool's filtration system. They require an additional line to the sewer for backwashing. The backwashing effect occurs cleaning the filter, and the sand typically needs replacement every five to eight years based on usage.  Glass Media tends to last a little longer, and will usually be replaced every 10 years. 

On the other hand, cartridge filters are also a great filtration system to filter the water. Cartridge filters don't require an additional plumbing line to sewer and can be more cost effective initially.  They do, however, require regular manual cleaning rather than backwashing and it is definitely not recommended to use any flocculent with a cartridge filter in place.


Maintenance involves removing and either washing or replacing the pool filter cartridge. Although they reduce energy costs by using low pump pressure, they  require more frequent cleaning, particularly during heavy pool dirt removal at the beginning of a new season.

While cartridge filters might demand more regular cleaning, their advantage lies in not requiring backwashing, which eliminates the need to replace chemicals in the refill water, ensuring a balanced pool environment.

Filtration Facts
  • The purpose of the pool’s filter is to keep the water clean and clear by removing dirt, algae, particles, and other stuff that makes the water cloudy.  Glass media takes out much smaller particles and is superior over sand media.

  • Glass media removes particles down to 3-5 microns.A micron is very small – a millionth of a meter.  Cartridge filters work around 10-20 microns when they are working correctly and sand media filters 20-40 microns right after they are backwashed, and get down to about 75 microns when they are dirty. 

  • Cartridge filters clean the water better than sand, and are fairly inexpensive to buy.  Supposedly, they are better for the environment, but that’s sort of a “Paper vs. Plastic” argument.  If you use tap water to wash them off, they put fewer chemicals into the environment.  Then, someday, you put the old cartridge into the trash and it goes into the landfill for 1000 years!

  • In our experience, cartridge filters are easily overwhelmed by an algae attack.  When they are old and soft, they allow dirt to go right past the cartridge and back to the pool.  Owners of cartridge filters are often fighting cloudy water.  

  • A sand filter is a very simple apparatus – it’s basically an empty bucket filled with sand or glass media.  As water passes down through the sand/glass, dirt is caught in the spaces between the pieces of sand/glass.  When the sand/glass is full of dirt, you flush it out by running the pool water backwards through the sand/glass and out to waste.  This operation is called backwashing and is done roughly once a week. Obviously, how much and how often is variable and depends on usage, etc.  Sand can be reused for a number of years, but it’s actually cheaper and easier to throw it out when you are replacing it. Sand filters are very easy to operate.

    The real differences? A sand filter, with its deep-bed filtration, is highly effective in trapping impurities, offering superior water clarity. Unlike cartridge filters, which need frequent cleaning, sand filters require less maintenance and boast a longer lifespan. This means less hassle for you and more time enjoying your pristine pool
