Pool volume refers to the amount of water in your pool.

In this way, and reiterating what has been said, being volume is the amount of space that a three-dimensional object occupies and specifically referring to the capacity of the liquid, in this case water, which is the amount of space that a liquid occupies to fill its container, in this supposed pool glass.

Then, The volume of a pool is just a rough estimate of the total number of liters of water the pool can hold, also known as the pool's capacity.

What do we mean by pool water level?

Simply, the water level of your pool only refers to how full your pool is.

The chemical composition of your water will always matter. But in this case, we are only talking about volume.

Because while it's important to keep the sanitizer, pH, and all those other superstar liquids you balance every week, it's just as essential to maintain the amount of water in your pool.

Where should my pool water level be?

Regardless, it is not relevant what the size of the pool is, the water level is recommended to be between half and 3/4 of the skimmer box opening / plate (opening / window).

How to check the pool water level

On the other hand, checking the ideal water level for the pool is a simple process since you only have to make sure that the water is at the midpoint / three quarters of the hatch of your skimmer.

What is the normal loss of water level in a swimming pool?

What affects pool water levels?

The main causes of evaporation of pool water
Loss of water in the pool considered normal
  1. Firstly, certain weather conditions affect pool levels, for example: Heavy rains add too much water to the pool. The drier the air, the faster the rate of evaporation. In high humidity conditions, evaporation is less. Another decisive factor that influences the speed of evaporation is the wind, the higher the wind, the more evaporation.
  2. Secondly, they have a lot of impact periods of heat increase the amount of water evaporation.
  3. And, among many other factors, the number of bathers and the use of the pool itself is also a factor, as the water level will change when there are people in the pool because the more people in the pool, the more splashes there are.

Disadvantages when the water level is too low
  • First of all, if the water level in your pool is less than optimal, your skimmer will begin to suck air into the filter system and as a result can permanently damage the filter, as the filter is not designed to suck only air, but rather it needs adequate water flow to function efficiently.
  • Due to the lack of water, as a result, the motor of your pump is at risk of burning out.

What happens if the water level is too high?

Repercussions high level of the pool water
  • Although not as serious as a low pool water level, a high water level can still pose a minor threat to your skimmer.
  • Consequently, the increased inflow of water can reduce the efficiency of the skimmer, which creates a greater chance of maintenance work so debris floating next to the opening can pass through without being entrained by the skimmer.

Repercussions of the loss of water in the pool

  • In the first place, the waste of the pool water means a fairly high economic expense.
  • Second, energy expenditure, pool chemicals and derivatives.
  • In addition, all this has an environmental impact.
  • It can also cause damage to the pool pump, since it is the only water inlet for filtration and no water reaches the engine.
  • Consequently, the values ​​of the pool water regarding the pH and chlorine will be misadjusted. Well, in this case we recommend you consult: how to lower pH pool y how to raise the pool pH.

  • Initially, it is imperative to keep the water level at least more than half full at all times. between rain and evaporation, the water level in your pool will never be the same, so now you should prepare to check the water level in the pool
  • In the background, i have a filter system that requires backwashing, be sure to keep an eye on the water level and refill as needed.
  • At the same time, comparing the height of the water with the skimmer screws is a good way to keep track of the water level when you suspect a leak.
  • Besides, an above ground pool relies on water to maintain its structure.
  • An empty pool on a hot day or even a pool with little water can cause the liner to shrink and require replacement.
  • Meanwhile An empty swimming pool is also susceptible to collapsing in strong winds or bad weather.
  • After all, whenever you replace the water in your pool, both the removal and the filling must be completed on the same day.

Water level control problems in swimming pools

To conclude, clarify that water leaks in swimming pools are one of the main problems they have.

Thus, If you notice that your pool's water level drops even during periods of low usage, you should investigate the filter liner and pipes for signs of leaks.

M3 what is it
M3 what is it

The cubic meter is a unit of volume.

  • First of all, mention that The cubic meter is the consistent unit of the International System of Units to measure volume.

Equivalence of m3

  • The m3 corresponds to the volume of a cube with a side of one meter, and therefore, exactly, m3 is the identity of a kiloliter.

Units used to measure volume = liter equivalent to dm3

Thus, Since the cubic meter is a very large unit for measurements that are normally used in daily life, the liter is used more, which is equivalent to the dm3

The capacity or volume of a pool (LIQUIDS) is measured in liters

We measure the capacity of liquids in units of volume liter

  • To measure the volume of irregular solids we need graduated instruments. Next, we give the example of the procedure to measure the volume of a stone (irregular solid).
Procedure: Measure the volume of irregular solids
  1. The first step is to put water in a test tube, in this case, up to 22 mL.
  2. Secondly, we introduce the stone in the same test tube with water.
  3. Immediately afterwards, we observe that the water rises to 26 mL. So the amount of water displaced by the stone is equivalent to its volume, consequently, we subtract to know the amount of displaced water: 26 mL – 22mL = 4 mL.
  4. Now we can know that the volume of our irregular solid (stone) is 4mL.

Formula to calculate cubic meters swimming pool: Length X Width x Depth

Procedure to calculate cubic meters swimming pool

  1. Width and long. Start by measuring the width and length of your pool in meters. 
  2. Surface (area). To know the surface, multiply the width by the length and you will have the value in square meters (m2).
  3. Calculate the mean depth. First find out how long the deepest part of the pool is. Then calculate the shallowest part. Adding these two data and dividing by 2 will obtain the average depth. Although, in the event that your pool has the same depth throughout the floor, of course, the average depth will be the only depth.
  4. Volume. By multiplying the area by the depth, we can find the volume in cubic meters (m3).
  5. litres. To express cubic meters in liters, simply multiply the volume by 1.000.
