What does the MultiCyclone do?

MultiCyclone is capable of saving water and reducing filter maintenance. The MultiCyclone works on the basis of centrifugal water filtration. There are no moving parts to wear and tear and no filter media to clean or replace.


Incoming water is guided by a diverter plate so that it enters multiple hydro cyclones tangentially generating a strong centrifugal effect. This spins the sediment out to the hydro cyclone's wall and then spirals it down to the sediment chamber, while the cleansed water spirals upwards.


The accumulation of sediment can be visibly monitored through the MultiCyclone's clear sediment chamber. The MultiCyclone is cleaned by simply opening the purge valve. Only 15 litres (about 4 gals) of water is discharged to clean the MultiCyclone of sediment.


MultiCyclone is ideal as a pre-filter to extend the life of your existing filter. MultiCyclone will filter out up to 80% of incoming sediment from your swimming pool.


·      Save Water.

·      Reduce backwash frequency.

·      Reduce filter cartridge maintenance.


Please note: The MultiCyclone is designed to filter sediment that is heavier than water, floating debris cannot be filtered out by centrifugal filtration.

The Pool Cartridge Filter

Magnified and demystified

One of the most important aspects of proper pool maintenance is proper water flow through filtration.  Proper flow means lower energy cost, better quality water, less chemicals, and longer equipment life.  Cartridge filters are one of the more common filter medias.  

Cartridges have  a huge difference in quality and with that price.  Pricing differences are constantly raising concerns in the consumer's eye.  The most dramatic quality difference is in the filter media.  The poorest quality and thus generally the cheapest are no more than paper with the best being a true fabric.  Fabric technology is changing rapidly with major changes that mean easier to clean, greater dirt holding capabilities, and longer life.  Cartridge fabrics have different weights fabrics, some contain antimicrobial, and the best are of the newest and most advance designs.

Advances in cartridge development has led to  “point bonded” filtration fabric. This media contains more fibers per unit area to offer far greater volume and dirt holding capacity than other filtration fabrics. With reduced pore size distribution, the new fabrics provide superior filtration via unique localized cross flow filtration, which easily and efficiently captures dirt particles to achieve a deeper level of water cleanliness and clarity. With uniformly placed bonded weld spots and uniformly distributed fibers, the advanced-bonded fabric is strong and returns to a high state of original performance after cleaning.  A high-end manufacturing technology is used to create this new fabric, in which heat melts the fibers together. The result is a stronger fabric, which locks in the pore size distribution for capturing dirt of greater varied particle sizes, thus allowing the filter to clean the water faster and more efficiently.  Let B&L show you the difference between the paper, and  the different quality fabric cartridges.  When you want a cartridge that lasts longer, cleans easier, holds more dirt, and filters more efficiently, come to B&L for your cartridge needs.

We here at B&L are proud to carry Filbur and Pleatco filter cartridges which are some of the best on the market.

Shop locally

I had the pleasure being able to tour the plant located here in Phoenix.  I was surprised at how incredibly quickly and efficiently the entire process ran.  The products are made and delivered in the same day, guaranteeing freshness.  

Local company=money in the community we all live in. The opportunity to meet with the employees for Apex really gave me an accurate look at just how dedicated this company is to providing the best with little to no waste.

Using a closed piping system, the liquid chlorine and muriatic acid are packaged in an on-demand basis. This type of closed system prevents chemical vapors and waste. The strength of their pool products are quality tested every five pallets to make sure that every shipment is up to Apex standards. Products are packaged in gallon plastic bottles with child-resistant safety caps and distributed in high strength corrugated cartons. Safety and strength is of utmost concern. All of the products used are local-you can’t beat that!  

It is always a plus, when you are able to spend your money locally.  It's good for all of us in the community.  Come in and check out the liquid chlorine and muriatic acid that we are carrying from Apex Chemical Corporation.

Commercial Pools Be Advised

To remain VGB compliant - all main drain covers need to be replaced every 5 years. It has been five years sind the Virginia Graeme Baker Pool & Spa Safety Act became effective - meaning it's time for public facilities to start replacing their pool and spa drain covers.           

Sand Filters

Sand Filters

Sand filters in pools are used to extract impurities from the water by utilizing sand to collect debris as tiny as twenty microns. To discharge water waste, the sand filter must be backwashed (i.e., running the filter in reverse).  It is important to note that as a sand filter gets dirty it filters finer and finer particles.  So it becomes important to NOT backwash too often.  A clean sand filter will filter only to 20 microns as it gets dirty it can get down to 5 to 7 microns.  


Sand Filter Maintenance

Sand filters are relatively simple to maintain. 

Backwash Instructions

The sand filter should be backwashed whenever the pressure rises to 5-7lbs above normal “clean operating pressure”.  On a heavily used pool, this might be every couple of days.  On a lightly used home pool, this might only be once each week.  When a pool is professionally serviced, it should be backwashed on each visit.

Sand Change Instructions

The sand in the filter should be changed every two to three years on heavily used pools or pools with a lot of oil and every 5 to 7 years onnormally used pools.  Sometimes the sand can fail in as short as a year's time if oil, poor chemistry is maintained, or if the filter is abused.  If the water is cloudy and it is clearly not related to water chemistry, then check the condition of the sand and replace if needed. 

DE Filters

D.E. Filters

Diatomaceous earth (D.E.) is mined and is the fossilized exoskeletons of tiny diatoms. They are used to coat "grids" in the filter housing and act as tiny sieves allowing for the removal of debris as small as 5 microns. Once the pressure rises, the filter is backwashed just like a sand filter and then "recharged" with more D.E. powder. D.E. filters trap debris as small as 2 - 5 microns.


DE Filter Maintenance

A DE filter offers the best possible filtration, but it also requires the highest level of maintenance. 

Backwash Instructions

DE filters should be backwashed when the pressure rises to 5-7 lbs above “clean operating pressure” or every four to 6 weeks, whichever is sooner.  The DE clean should be done once or twice each year.

A good rule of thumb is to mark or note the “clean operating pressure”.  The “clean operating pressure” is the pressure the system runs at when the de filter grids are fairly new, clean and all the baskets are clean and the pool is set in normal operation.  This “clean operating pressure”, if known, can indicate time for cleaning, time to replace the grids, and/or other problems with the pool or filter.


Filter Cleaning Instructions

If the DE filter goes less than 3-4 weeks between backwashing on a home pool or the pressure is not going down to the “Clean operating pressure”, then it may be time for a DE filter clean.  Most filter manufacturers recommend that the DE clean should be done 1-2 times per year.
