Frequently Asked Questions

What is Lothorian Pools?

The name Lothorian was originally inspired by J. R. R. Tolkien’s Lothlorien, the beautiful gardens in the fictional universe of Middle-Earth. Adapted, our definition of Lothorian is a state of mind, referring to a natural environment of peace and tranquility where family and friends gather to enjoy life.

Why saltwater in a swimming pool?

A saltwater system creates a better, healthier swimming experience for most people. In a saltwater pool the water feels soft and your skin feels smooth and refreshed. Saltwater is healthier and safer for your hair, eyes, and skin. The amount of salt in a saltwater pool is negligible—3,000 parts per million—as compared to a tear (12,000 parts per million) or the ocean (33,000 parts per million).

Saltwater pools are NOT chlorine free pools. A saltwater pool is simply one that utilizes a chlorine generator. Chlorine generators have been around for decades. Chlorine is generated at the filter system by splitting the sodium chloride molecule. With a salt generator it is not necessary to handle or buy chlorine tablets. The interesting fact about salt generation is that while chlorine levels at the generator are at a super-chlorination level, 10 parts per million, the chlorine recombines with the water over the length of the piping and the result is a chlorine level of 1 part per million in the pool. Municipal drinking water also has a chlorine level of 1 part per million. This residual chlorine present in the pool eliminates algae and waterline scum build-up.

What is Winter Maintenance?

Winter maintenance is the management of water chemistry to ensure a longer life for the pool’s interior finish and monitoring of water levels to protect the tile and coping from the effects of freezing and thawing. We will also survey the cover to ensure that it is safe and secure. This service provides monitoring for the filter system, winter plugs, and plumbing lines to ensure the stability of winterization.

Is diving safe?

Yes, as long as it is done from a specified diving area into an appropriate dive envelope. We prefer to use a dive rock in our designs for two reasons: first, they look cool; and second, because there is no springy, bouncing action. A stable rock is a safer platform. Lothorian conforms to the American National Standards Institute (ANSI) safe diving envelope standards on all of our pools.

Why a Diatomaceous Earth filter?

A diatomaceous earth (D.E.) filter is the most efficient filter on the market. Water is filtered through porous, microscopically small, sponge-like particles that are able to remove particles to 4-5 microns as compared to a sand filter that filters to 40-50 microns. Municipal drinking water is filtered to 5 microns. The D.E. filter also has a greater ease of maintenance, as compared to the labor intensive cleaning of cartridge filters.

What is Diatomaceous Earth?

D.E. is a natural mineral called a diatom, which is a type of hard-shelled algae. An abrasive, fine white powder, it’s chemical composition consists of 86% silica, 5% sodium, 3% magnesium and 2% iron.

What is the seasonal cost of pool operation?

Please see the Maintenance Plans section of this website for details on our maintenance contracts.

Why use a PebbleTec product as the pool’s interior finish?

The lifespan of a PebbleTec® pool finish is 20+ years as compared to a traditional plaster finish at 7-10 years. PebbleTec also warrants their product for five years as compared to a one year guarantee with traditional plaster finishes. The reasons are evident in the content of each finish’s composition.

A PebbleTec® finish consists of 50% cement and 50% silica (stone). PebbleTec products are consistent in their color and pebble distribution throughout, and the thickness of the finish is 3/8” to ½”. Because 90-95% of the surface is pebbles, it is much more resistant to acid and poor water chemistry. It is also more resistant to staining and in the unlikely event of the need for a repair to the finish, seeing the patch is far less likely.

Traditionally used, plaster is a combination of 40% cement and 60% calcium carbonate (crushed marble). On the Mohs Scale of Mineral Hardness, marble is a 3 and silica is a 7. (For comparison, a diamond is 10, a fingernail 2.5, and a hardened steel file is a 7.) When applied, plaster is troweled until the “cream” is brought to the surface. That cream consists of calcium carbonate and cement. The cream hardens and becomes a protective layer approximately the thickness of two to three sheets of paper. Because the protective layer is so thin, an acid bath or the effects of pool chemicals over time are damaging to plaster.

What are the benefits of an automatic cover system?

We use only the Coverstar cover system for its superior quality and unparalleled customer service. There are four reasons for you to purchase a Coverstar automatic cover system: energy savings, environmental conservation, safety, and convenience.

The savings in monthly costs of operation are between 50-90%. You will save on consumption of electricity for heating the pool and running the filter systems, the addition of water and chemicals due to evaporation, and the life of all of the pool’s filter and maintenance components because the system is not running as frequently.

Use of a Coverstar system is also good for the environment. Because the cover acts as a solar panel, you will be conserving gas used for operating the pool heater. Closing the cover will protect the pool against the effects of evaporation, so you will be conserving water and using 70% less pool chemicals. You’ll also be conserving energy and reducing pollution because the pump and filter will only have to run for a few hours a day.

A closed pool cover is the best way to protect your family. Coverstar systems use only cover fabric which is tested and certified to meet the American Standard for Testing and Materials (ASTM) standard for safety pool covers. A keyed security box contains the switch that opens and closes the cover. You will have peace of mind knowing that no one is able to gain access to the switch without the key. This box must be located within sight of the pool to ensure that no one is in the pool while the cover is being closed.

Using a cover will allow you to extend the swimming season, since opening the pool earlier and closing much later in the season gives you the opportunity to take advantage of warm spring and fall afternoons. Keeping the cover closed also ensures a much cleaner pool, saving you the time and effort of extra skimming and vacuuming. To learn more about the benefits of a Coverstar automatic cover, visit
