Pool without fish = no filtration? 3 major misconceptions that 90% people have stepped on, #2 is so anti-common sense!

       The need for a filtration basin for a pool that does not support fish depends on the purpose of the pool, water quality requirements, and maintenance goals. Here are some key considerations and recommendations:

1. Is a filter tank required?

• Landscape Pools/Decorative Pools::
  If the focus is on aesthetics (e.g., clear water, prevention of algae growth), theRecommended to install a filtration system.. Even in the absence of fish, fallen leaves, dust, and algae spores can still affect water quality.
• Cisterns/irrigation ponds::
  If used primarily for water storage, filtration needs are low, but simple filtration devices (e.g., screens) can be installed to intercept large particles of contaminants and prevent clogging of pipes.
• natural pool::
  If natural balance is sought, plant purification (e.g., reeds, water lilies) can be used in place of mechanical filtration, but sediments need to be cleaned regularly.

2. Role of filtration systems

• Removal of impurities: Filters leaves, sediment, and suspended matter to keep water clear.
• Inhibition of algae: Algae blooms are reduced by circulation and UV Clarifier.
• Reduced maintenance: Reduce the frequency of manual cleanups and extend water change intervals.
• Enhancing Security: Prevent mosquito breeding or bacterial contamination (especially in pools where children may come into contact).

3. Recommended filtering schemes

A. Basic filtration (low-cost, low-maintenance)

• mechanical filtration::
  • utilization Skimmers (Skimmer) Collection of water surface floaters.
  • mounting Strainers or settling tanks Intercepts larger particles.
• vegetative filtration::
  • Plant aquatic plants (e.g., water hyacinth, bromeliads) to absorb nutrient salts and inhibit algae.
  • devise Bog Filter Area (Bog Filter), allowing the water to flow through the plant's root system to purify it naturally.

B. Advanced filtration (efficient water quality management)

• Sand Tank Filter::
  Suitable for small to medium sized pools, retains impurities through quartz sand and requires regular backwashing.
• UV Clarifier::
  Kills algae spores and bacteria, works better with circulation pumps.
• Integrated filtration systems::
  Integrated mechanical, biological and chemical filtration modules for landscape pools with high water quality requirements.

4. Design elements

• recirculating water: Install pumps to ensure water movement and avoid stagnant areas.
• filtration capacity: Select the filter flow rate according to the pool volume (1/2 to 1 times the total amount of circulating pool water per hour is recommended).
• Ease of Maintenance: Reserve cleaning port or backwash pipe for daily maintenance.

5. Alternatives to unfiltered

• Regular water changes: Manual cleaning of the bottom of the pool and frequent replacement of part of the water (suitable for very small pools).
• chemical treatment: Use algaecides or clarifiers, but be aware of the risk of chemical residues.
• ecological balance: Self-purification systems through fish (e.g., mosquito-eating fish), snails, or microorganisms.

Summary of recommendations

• Small landscape pool: Choose an integrated filter or swamp filtration with a UV sterilizer.
• Large water reservoirs: Installation of a primary screen and settling tank is sufficient.
• natural pool: Rely on plant purification and regular manual cleaning.

Depending on the specific needs and budget, a properly designed filtration system can significantly enhance the practicality and aesthetics of your pool. If you still have questions, we recommend consulting a professional water feature designer for customized program planning.
