35+ years of hands-on pool construction, chemical dosing, and maintenance experience, distilled into short, specific answers — no jargon, no guesswork.
The ideal pH range for swimming pool water is 7.2–7.4. This range keeps chlorine's disinfecting power at its most efficient level, prevents eye and skin irritation, and protects equipment from corrosion. Above pH 7.8, chlorine's effectiveness drops noticeably.
Read the answer →Chlorine dosage is calculated based on pool volume (m³), water temperature, bather load, and the type of chlorine used. The target is 1–3 ppm free chlorine for private pools and 1–5 ppm for commercial/public pools. Accurate pool volume is essential for correct dosing.
Read the answer →Pool water turns green when free chlorine levels drop and algae growth begins. This is usually caused by irregular chlorination, insufficient filtration runtime, or unbalanced pH. The fix is shock chlorination, an algaecide treatment, and running the filter continuously until the water clears.
Read the answer →Total alkalinity is a buffer value that shows the water's resistance to pH swings, with an ideal range of 80–120 ppm. Low alkalinity causes pH to fluctuate rapidly, while high alkalinity makes it difficult to move pH into the target range. It is raised with sodium bicarbonate and lowered with acid.
Read the answer →Cyanuric acid (CYA) is a stabilizer that protects chlorine in outdoor pools from rapid breakdown by UV sunlight. The ideal level is 30–50 ppm. Too little CYA accelerates chlorine loss, while too much (above 100 ppm) suppresses chlorine's disinfecting power — a condition known as chlorine lock.
Read the answer →Building a standard villa swimming pool typically takes 45–75 days, depending on weather conditions and project scale. This covers excavation, reinforced concrete, waterproofing, mechanical installation, finishing, and commissioning. Specialized projects (infinity, olympic-size) can take longer.
Read the answer →Family/villa pools are typically designed with a constant depth of 1.20–1.60 m or a graduated depth of 1.0–1.80 m. Diving pools require a minimum of 3.0–3.8 m for safety, while World Aquatics competition standards require a minimum depth of 2.0 m for olympic racing pools.
Read the answer →In skimmer pools, surface water is drawn through skimmer openings at the pool edge and sent to filtration; the water level sits slightly below the deck. In overflow pools, water continuously spills into perimeter channels and collects in a balance tank; the water level is flush with the edge, giving superior surface skimming.
Read the answer →Filtration system selection depends on pool volume, target turnover (circulation) time, bather load, and budget. Sand filters are economical and common, cartridge filters use less water for cleaning, and diatomaceous earth (DE) filters provide the highest water clarity but require more maintenance.
Read the answer →Pool cost is driven by size and volume, ground/excavation conditions, the chosen system (skimmer vs. overflow), finishing material (ceramic, mosaic, liquid membrane), automation level, and add-ons such as heating and lighting. Site access and distance to infrastructure also affect transport and labor costs.
Read the answer →A salt chlorine generator adds a low concentration of salt to the pool (typically 3,000–4,500 ppm), then passes the water through an electrolysis cell to produce chlorine electrochemically. This provides continuous, automatic disinfection without manually adding bagged or tablet chlorine. The water is far less salty than seawater.
Read the answer →A properly sized and well-maintained salt chlorine system does not damage the pool. However, if salt levels are kept too high, unprotected metal fittings are used, or the system is undersized, corrosion and scale buildup on the electrolysis cell can occur over time.
Read the answer →A quality electrolysis cell has an average service life of 3–7 years when properly sized and maintained. The main factors affecting lifespan are total runtime, salt concentration, water quality, and whether the cell is cleaned regularly.
Read the answer →For an average villa pool, a salt chlorine generator typically draws 100–300 W during its 3–8 hour daily operating cycle, adding roughly a few kWh to a few dozen kWh per month. Actual consumption depends on pool volume and the target chlorine output level.
Read the answer →In a salt water pool, disinfecting chlorine is produced on-site from salt via electrolysis; in a traditional pool, chlorine is added directly from an external source (tablets, granules, or liquid). Salt chlorine pools offer a softer water feel, less chlorine smell, and less manual dosing.
Read the answer →For villa pools, water chemistry (pH/chlorine) should be checked 2–3 times a week, floor vacuuming and surface skimming done weekly, and filter backwashing performed every 2–4 weeks. High-traffic commercial pools require daily checks and weekly detailed maintenance.
Read the answer →In outdoor pools, an average water level drop of 3–6 mm per day (roughly 1–2 cm per week) from evaporation is normal. If the drop is significantly higher than this, especially when it continues even with the pump off, a leak in the shell or piping should be investigated.
Read the answer →Winterizing involves balancing water chemistry, cleaning and either draining or antifreeze-protecting the filtration system against freezing, lowering the water level below the skimmer, and covering the pool with a winter cover. Proper winterization prevents freeze-related equipment damage before the spring re-opening.
Read the answer →The annual operating cost of an average villa pool consists of chemicals, electricity (pump/heating), water top-up, and periodic maintenance/equipment expenses, and varies significantly based on pool size, usage frequency, and the systems chosen (salt chlorination, heating, automation).
Read the answer →In a well-maintained pool, a full water drain and refill is typically needed every 3–5 years. This interval can shorten when dissolved solids (TDS) build up, cyanuric acid levels get too high, or another chemical imbalance can no longer be corrected without replacement.
