Have a look at some of our most common questions by our customers.

The filter keeps most of the small particles that fall into the pool. The pump brings the pool water into the filter. The power of the pump needed depends on the size of the pool, the type of filter and the distance of the machinery room from the pool. Lanse will advise you, which pump is best for your pool.
Most pools we see are made in a parallelogram shape, especially private pools.
This is mostly for practical reasons and not compulsory reasons. Therefore a pool can be of any size and can finish at any depth.
The first visible restrictions we will come across are the space available, and the expense needed for the construction of the pool. A small (restricted) area consists in a smaller size pool, while a long area urges a similar construction.
The most important factor in the cost of the pool is its size.
Every meter or square meter that we add raises the cost not only for the construction but also for the surfacing material, the volume of the water, and the necessary equipment.
Lets not run into a conclusion since there are many examples of small ‘rich’ pool exceeding the cost of a big ‘poor’ pool.
Farther restrictions require special knowledge and differ depending on the situation.
An example is the correct construction of the length and depth of the shallow part of the pool, so it may give the same feeling as the shallow part of a beach.
Another example is the heating of the pool. If we wish to have a heated pool the placement of a pool cover is essential. A heat-insulating cover may be placed only on certain pool shapes.
The ideal temperature of the pool water is subjective, so the answers may differ.
From our experience we have seen that the perfect temperature, for most people, is between 26 and 30 degrees Celsius. For example a pool in Attiki (Athens) may have that temperature (under normal circumstances) from the end of June until mid September. Seeing that in Greece the sunny days may exceed those months by far, the desire to lengthen the swimming season just as much arises. This is where a heated pool is considered essential so we may continue to enjoy our pool even longer .
To answer that question it may be better to see what the covers are useful for.
Pool covers have three basic characteristics.
The pool hygiene, protecting from dirt, leafs and whatever else may be on the pool surrounding from falling into the pool. Heat insulation, so as to decrees a large amount of energy that is needed to maintain the pool temperature. Pool Safety, to protect from possible accidents that may happen when the pool is either full of water or empty. There are different types of covers that can offer some or all of those qualities. The choice of cover depends on the need for each pool, and the aesthetics preference of the owner.
With a Skimmer pool we mean the situation when 50% of the water is led to the machinery room through the skimmer that is built into the top half of the pool wall (the other 50% is always taken from the pool bottom).
With an Overflow pool we mean the situation when 50% of the water led to the machinery room is taken from the overflow tank – channel that has been built around the pool (the water runs over the pool wall and into the overflow channel).
On a Skimmer pool the water level is about 10 to 30cm lower than the pool surrounding.
They are easy during construction because only the skimmer has to be fitted into the wall through which the water is led to the machinery room.
For an Overflow pool the construction is more complex. A channel is needed around the pool walls as well as an overflow tank that stores the water before it is led into the machinery room. On an Overflow pool the water is at the same height of the pool surrounding, so it blends it.
With the term “winter” we mean the period of time when we stop swimming until the next season. Many owners like to enjoy the view of the pool even during that time. For these situations it is better to keep the machinery working a few hours a day. In the situation where the owner prefers to forget about the pool it is best to cover it with a pool cover.
It is better to leave the pool full with water to avoid any accidents and also to protect the pool walls and facing from the sun and the change of temperature. The cover is set for extra safety and to avoid the creation of a swamp.
A well taken care of filter can keep most particles out of the water but the water needs to be disinfected with some chemical, for example Chlorine. Chlorine will kill bacteria and algae while it will oxidize the unwanted and annoying organic combinations.
If the chlorine level falls lower than 1 ppm for a certain time, a green thin layer of algae will be visible on the pool walls. That layer will spread to the major volume of the water, turning the pool green and giving out a foul scent. The appearance of algae is usually a sign of insufficient disinfection. To deal with it you may need the help of Lanse specialists.
pH is the measurement of acidity or alkalinity in the water. A neutral solution like distillate water has pH 7. A solution lower than pH 7 is called acidic while a solution more than pH 7 alkaline. Under normal circumstances the appropriate pH of the pool water must vary between 7,2 to 7,8.
Balanced water is a term used to describe the ideal state of water entering the pool. The water is balanced if it has the right pH, hardness and dissolved total solids. Water with high hardness can become cloudy and cause sand filters to calcify, reducing their ability to operate.
