Why does the water in a swimming pool turn green?

The color green is usually associated with the proliferation of algae, although the causes that have allowed its appearance may be different in each pool.High temperatures, rain, periods without maintenance, filtration problems, water imbalances or insufficient disinfection can contribute to the deterioration of the pool.For this reason, before adding products indiscriminately, it is important to check what is happening and adapt the treatment to the actual conditions of the installation.A pool with green water may need to combine water treatment, physical cleaning, and filtration to achieve proper recovery.

Professional treatment of swimming pools with green water and algae

Regular cleaning is essential to maintain crystal-clear water and prevent damage to the filtration system. At Terranova Services, we perform professional cleaning using both manual tools and automated equipment to keep your pool in perfect aesthetic and hygienic condition.

Initial water analysis

We checked the general condition of the pool and the main parameters related to water treatment.This assessment allows us to determine what imbalances may be contributing to the appearance of algae.

Algae treatment

We apply the appropriate treatment according to the condition of the pool and the level of proliferation present.The action must be adapted to each case and not simply limited to adding products to the water.

Brushing of walls and bottom

Algae can remain attached to the pool liner.When necessary, we carry out brushing and cleaning work to remove them from walls, bottoms, stairs and other surfaces.

Water recovery

Once the treatment has been applied, we work to progressively restore the transparency and proper conditions of the water.The time required will depend on the initial condition of the pool and the causes that led to the problem.

Leakage review

The water treatment plant plays a fundamental role during the recovery of a green swimming pool.We check that the filtration system can work correctly and review any problems that may be hindering the water cleaning process.

Monitoring the evolution

In certain pools, it may be necessary to carry out a second check to assess the progress of the treatment and make further adjustments.

Problems we can find in a swimming pool with deteriorated water

There are several signs that may indicate that water parameters need to be checked.

Completely green water

A significant proliferation of algae can noticeably change the color of the pool and considerably reduce the visibility of the bottom.In these cases, a more comprehensive intervention is usually necessary.

Algae on walls and bottom

Although the water may still retain some transparency, green areas or slippery surfaces may appear on walls, steps and the bottom.

Murky water

Loss of transparency may appear alongside other imbalances or after starting recovery treatment.

Green water after several days without maintenance

High temperatures and uncontrolled periods can accelerate water deterioration, especially during the summer months.

Problems after rain or heavy use

Certain weather conditions and periods of heavy use can quickly alter the balance of a swimming pool.

How do we restore a swimming pool with green water?

Properly maintained equipment helps keep water clean, reduces chemical consumption, and prevents costly breakdowns in the long run. At Terranova Services, we perform regular technical inspections to ensure the efficient operation of all system components.

Water imbalance

Parameters outside of the appropriate conditions can reduce the effectiveness of the usual pool treatment.

Insufficient filtration

A filtration system that is not working properly can hinder the removal of particles and contribute to the deterioration of the water.

High temperatures

During the warmer months, the water needs more frequent monitoring due to environmental conditions and increased pool usage.

Periods without maintenance

Swimming pools in second homes or houses that remain unoccupied can deteriorate rapidly if they go too long without being inspected.

Rain and dirt outside

Rain, dust, leaves, and other debris can alter water conditions and increase treatment needs.

Intensive use of the pool

During periods with many bathers, it may be necessary to increase the frequency of monitoring and maintenance.

Frequently asked questions about pool filters and purification systems

At Terranova Services, we answer some of the most common questions about pool maintenance in Marina Alta. Professional maintenance helps keep the water clean, prevent breakdowns, and ensure the proper functioning of the entire pool year-round.

The most common cause is the proliferation of algae, although it can be related to various factors such as water imbalances, insufficient filtration, high temperatures, or periods without maintenance.

It is advisable to check the condition of the pool before deciding on the treatment.

In many cases it is possible to recover the water, but the necessary action will depend on its condition, the time elapsed and the functioning of the equipment.

First we need to assess the pool.

There is no single time that applies to all swimming pools.

It will depend on the degree of algae proliferation, water volume, filtration status, initial parameters, and response to treatment.

Not necessarily.

Before considering draining, it is advisable to assess whether the water can be recovered through treatment, filtration, and cleaning.

There may be an underlying problem that has not been addressed, such as a persistent imbalance, insufficient filtration, accumulated dirt, or inadequate maintenance.

That’s why it’s important to identify the cause.

Not necessarily. A strong odor can appear for various reasons related to the water’s condition, so it’s advisable to take measurements before modifying the treatment.
