Welcome to the Ultimate Water Treatment System!

Thank you for allowing us to offer you the ultimate in water treatment for your pool!
Whether you elected our fine chemical service or a more comprehensive full maintenance program, we will do our best to ensure your satisfaction.

We apply only the finest chemicals to your swimming pool including specially blended liquid chlorine as well as other chemicals used to balance and maintain the water. With our service, you will probably notice a marked improvement in water clarity as well as a more comfortable pool in which to swim. You might also notice that we are extremely efficient and will perform all our duties at your pool quickly.



We do have a $60.00 start-up fee that includes the proper conditioning of your pool. Thereafter, we have an annual conditioning charge of $60.00. Unfortunately, this policy cannot be offered to customers whose pools fall into the following categories:
-Pools larger than 40,000 gallons; $2.00 per pound for conditioner.
-Pools with excessive water loss; $2.00 per pound of conditioner.


We perform our service every week with the exception of Thanksgiving, Christmas and New Year’s weeks. Our personnel will add sufficient chemicals prior to these holidays to ensure that your pool remains fully chlorinated and balanced. Memorial Day, Labor Day and Independence Day are regular service days unless you advise us to skip any of those days.
If you plan a large swim party, call our office the week before and we will add extra chemicals at no extra charge. Remember that there should be no swimmers in the pool for one hour after servicing. (This should be the case when any chemical is added to the water.)

Owner’s Responsibilities customer-service
FILTRATION IS EXTREMELY IMPORTANT. Your filter should be cleaned when the filter’s pressure gauge indicates a 6-8 pound increase in pressure above the clean pressure. The diatomaceous earth filter should be serviced semi-annually, replacing any worn parts and thoroughly cleaning the filter grids. The filter element(s) in the cartridge filter need to be replaced every 3 or 4 years or sooner if indicated. Our recommendation for the amount of time that your filter should be in operation daily is:

Cartridge filter- run 8-10 hours daily

Cartridge filers have a greater surface area than sand, allowing for fewer clogs and easier maintenance. They run at lower pressure than sand which puts less back pressure on the pump, providing more flow and turnover. Cartridge filters should be cleaned once or twice a season by simply hosing the cartridge element off. Cartridge elements filters trap debris as small as 10 to 15 microns.

D.E. Filters -run 6-8 hours daily

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 2-5 microns. Once the pressure rises, we recommend a complete disassemble (not backwash) so a thorough inspection of all internal components can be done, replacing any failed parts, reassemble and recharge with fresh D.E. This should be done every 6 months to insure optimum filtration.

Sand Filters- run 10-12 hours daily

In this method, impurities are extracted from the water using sand to collect and attract the debris as small as 20 to 40 microns. Sand filters must be backwashed (running it in reverse) to unload the water waste.


Pool Covers infin3b_large
If you use a pool cover, you should expose the surface of your pool water to the air 50% of the time. Your cover should be pulled back on service days. If it is not we will pull the cover back three or four feet and we will purposely leave it pulled back so that the water can be exposed to the air for several hours.

Solar Systems
If you have a solar system in operative, be aware that 50% or more can reduce the flow of water through the filter. Increase filtration time accordingly. Also, be aware that during our cold season, damage from water freezing and expanding within your panels can occur. To avoid this problem, arrange to drain you solar system prior to freezing conditions each year.

Cloudy Water
This condition is a result of insufficient filtration or an indication of a problem with your filtration system.

Because some strains of algae are more resistant than others, please allow us a reasonable period of time to completely eradicate it. The more resistant black algae will turn gray as it starts to die and will eventually disappear. Keeping your pool clean will aid in the treatment of algae.
