Pool questions, answered

Pools are categorized several ways: by construction (in-ground, above ground, semi-in-ground), by material (gunite or concrete, fiberglass, vinyl liner), by purpose (lap pools, family pools, plunge pools, exercise pools), by edge design (infinity or vanishing edge, perimeter overflow, beach entry), and by water type (chlorine, saltwater, mineral, natural). Most permanent designed pools are in-ground gunite pools, because gunite allows unlimited shape, depth, and features.

Gunite (sprayed concrete) pools are built on site in any shape, depth, or size and last for decades with periodic resurfacing, which makes them the standard for custom design. Fiberglass pools are factory-molded shells installed quickly, with limited shapes and sizes but a smooth, low-maintenance surface. Vinyl-liner pools have the lowest upfront cost but the liner needs periodic replacement. For a permanent, fully custom pool, gunite is almost always the answer.

In hot, humid climates an in-ground gunite pool is the standard, because it can be engineered for the soil, the high water table, and storm exposure those regions face. Saltwater sanitation is popular for its softer water feel, and features like a tanning ledge, a screen enclosure, and efficient variable-speed equipment suit year-round outdoor use. The pool should be engineered specifically for local conditions, not built to a generic spec.

An infinity pool, also called a vanishing edge, negative edge, or zero edge pool, has one or more edges built precisely level so water spills over into a hidden catch basin and is recirculated. The effect removes the visual boundary between the pool and the view beyond, creating the single most dramatic look in pool design. It demands exact engineering and is best built by a design-build company that engineers and constructs under one roof.

A plunge pool is a compact pool built for cooling off, relaxing, and entertaining rather than swimming laps. It fits courtyards and small or awkward yards where a full-size pool will not work, costs less to build and run because it holds less water, and can still include a spa, water features, and full automation. A plunge pool proves that limited space is not a barrier to a beautiful pool.

A tanning ledge, also called a sun shelf or Baja shelf, is a wide, shallow shelf built into the pool, usually a few inches to a foot deep. It is one of the most popular features in modern pool design: a place to lounge half-submerged, set chairs in the water, or let small children play safely within view. It can include bubblers and is far cheaper designed in than added later.

A natural swimming pool is kept clean by a planted regeneration zone and biological filtration instead of chlorine. The swimming area connects to a shallow planted zone where aquatic plants and beneficial bacteria filter the water. The result is soft, living, chemical-free water and a beautiful planted landscape feature. The trade-offs are the additional space the regeneration zone requires and a more sophisticated design and balance.

Geometric pools with clean straight lines suit modern and contemporary homes and are the most economical to build. Freeform pools with soft organic curves suit tropical, lagoon, and naturalistic landscapes. The right shape follows the architecture of the home, the shape and slope of the yard, and how the pool will be used. Shape is a design decision best made with a designer studying your specific property.

Depth should follow how the pool will be used. A family pool often blends a shallow zone of about three and a half to four feet for play and standing with a deeper zone of five to six feet for swimming. Diving requires significantly more depth and a specific bottom profile, and is a deliberate design choice. A pool built only for lounging and cooling off can be shallow throughout.

A spool is a spa and pool combined into one compact unit. It delivers a small swimming or cooling area together with a heated spa in a tight footprint, which makes it ideal for small yards, courtyards, and rooftops where a full-size pool will not fit. With a swim jet it can also provide a current to exercise against.

A pool needs attention weekly: testing and balancing the water, skimming and brushing, emptying skimmer and pump baskets, and checking equipment. Filters are cleaned periodically, not weekly. Many owners use a weekly professional service so the pool is reliably maintained and small problems are caught early. A robotic cleaner handles floor and wall cleaning between visits.

A typical weekly service visit includes testing and balancing the water chemistry, adding chemicals as needed, skimming the surface, brushing walls and steps, vacuuming or running the cleaner, emptying baskets, checking the filter pressure and the equipment, and confirming the pump and sanitation system are working. The value is consistency: balanced water and early detection of equipment issues.

Clear water comes from three things working together: adequate circulation (running the pump long enough each day), effective filtration (a clean, correctly sized filter), and balanced chemistry (proper sanitizer, pH, and supporting levels). When water turns cloudy, one of those three is usually off. Consistent weekly care prevents almost every clarity problem before it starts.

A green pool is algae, caused by a loss of sanitizer combined with warmth, sunlight, and poor circulation, often after a storm or a neglected stretch. Recovery means balancing the water, shocking it to kill the algae, running the filter continuously, and brushing thoroughly, repeating until the water clears. A badly neglected green pool is best recovered with a professional green-to-clean service.

A pool generally needs its full water volume turned over at least once a day, which commonly means running the pump several hours daily, more in summer and heavy use. A variable-speed pump changes the math: running slowly for a longer period filters effectively while using far less electricity than a single-speed pump run for a shorter time.

In cold climates, closing a pool means balancing the water, lowering the level as needed, blowing out and plugging the plumbing so no water can freeze and crack lines, removing and storing equipment baskets, and fitting a winter cover. Proper closing protects the plumbing and equipment and makes spring opening far easier. In warm climates pools usually stay open year-round.

Opening a pool means removing and cleaning the cover, reinstalling equipment, refilling to the proper level, restarting and priming the system, then testing, balancing, and often shocking the water and running the filter until it is clear. A thorough opening, ideally before the water warms enough for algae, sets up an easy season.

A robotic cleaner is the single accessory that most reduces the weekly effort of pool ownership. It is a self-contained robot that scrubs the floor, climbs the walls, and clears the waterline on its own, independent of the pool pump and filter, and traps debris in its own canister. For most owners it is well worth the cost.

Filter cleaning frequency depends on the filter type and the debris load, and is guided by the pressure gauge: when pressure rises a set amount above the clean baseline, the filter needs service. Cartridge filters are rinsed or replaced, sand and DE filters are backwashed and recharged. A clogged filter cannot keep water clear no matter how good the chemistry is.

Some water loss is normal evaporation, which increases with heat, wind, and sun and is greater for uncovered pools. Loss beyond normal evaporation can mean a leak in the shell, the plumbing, or the equipment. A simple bucket test compares pool loss to a reference, and persistent unexplained loss should be investigated with professional leak detection before it damages the structure or the surrounding ground.

A variable-speed pump can run at a low, quiet, highly efficient speed for everyday circulation and step up only when a task needs more flow. Because a pool spends most of its hours simply circulating, running slow for longer uses dramatically less electricity than a single-speed pump. The pump is usually a pool's largest energy user, and a variable-speed pump frequently pays back its higher price through energy savings.

Pump size is not a guess. The pump must be matched to the pool's volume, its plumbing, its filter, and its features. An oversized pump wastes energy and can strain the filter; an undersized pump cannot circulate the pool properly. Correct sizing is one of the main reasons a pump should be specified and installed by a professional rather than bought blind.

The main options are heat pumps, gas heaters, and solar heating. Heat pumps move heat from the air and are very efficient for moderate temperatures and season extension. Gas heaters heat water quickly and reach high temperatures regardless of weather, at a higher running cost. Solar heating uses roof-mounted collectors for a low running cost. Many pools pair a heater with a cover to retain the heat.

A heat pump is highly efficient and ideal for maintaining comfortable temperatures and extending the season, but it works more slowly and depends on adequate air temperature. A gas heater heats fast and can reach high temperatures in any weather, which suits spas and quick on-demand heating, but it costs more to run. The right choice depends on climate, how fast you want heat, and running-cost priorities.

A pool chiller lowers water temperature, which matters in hot climates where pools can become uncomfortably warm in peak summer and lose their refreshing effect. A chiller keeps the water cool and swimmable. Some heat-pump units can both heat and cool. In very hot regions, cooling is as valuable as heating for year-round comfort.

Pool automation lets you control and schedule the pump, heater, sanitation, lighting, water features, and spa from a control panel or a phone app. It runs equipment on efficient schedules, makes the pool easier to use, and lets a service company monitor and adjust systems. Automation turns a collection of separate equipment into one coordinated, efficient system.

The three main filter types are cartridge, sand, and diatomaceous earth (DE). Cartridge filters offer fine filtration and are rinsed or replaced. Sand filters are durable and simple and are cleaned by backwashing. DE filters provide the finest filtration and are backwashed and recharged. Each is a valid choice; the right one depends on the pool, the debris load, and maintenance preference.

Lifespan varies by component and care. A quality variable-speed pump, a heater, and a filter generally last many years when correctly sized, installed, and maintained, and salt cells, cartridges, and lighting are periodic-replacement items. Equipment that is undersized, poorly installed, or neglected fails far sooner. Good installation and regular service are what turn rated lifespans into real ones.

The highest-impact efficiency upgrade is a variable-speed pump, since the pump is the pool's largest energy load. Beyond that, an efficient heat pump, LED lighting, a pool cover to cut heat and evaporation loss, and automation to run everything on smart schedules all reduce running cost. Many efficient pool products carry recognized efficiency certifications.

Yes. With a modern automation system, the pump, heater, lighting, water features, sanitation, and spa can all be monitored and controlled from a smartphone app. You can heat the spa on the way home, adjust schedules, change lighting scenes, and see system status remotely. It also lets a service company support the pool without an on-site visit.

A swimming pool is an engineered, sanitized body of water built for swimming. A koi pond is a living aquatic ecosystem built for fish and plants, with biological filtration, aeration, and a depth and design suited to koi. They are different disciplines: a pool prioritizes clean water for people, a pond prioritizes a healthy environment for life. A skilled design-build company can also combine the two.

A koi pond's cost depends on size and depth, the excavation and structure, the filtration and aeration equipment, the rockwork and waterfalls, and the planting and stocking. A small water garden and a large, deep koi pond with elaborate waterscaping are very different projects. As with pools, the reliable way to budget is a design consultation and an itemized proposal.

A pondless waterfall is a waterfall and stream with no open pond at the bottom: the water disappears into a hidden gravel-and-basin reservoir and is recirculated. It delivers the sound and movement of running water with a small footprint, low maintenance, and no open water, which makes it a popular choice for front yards and homes with young children.

Clear pond water comes from a balanced ecosystem: adequate biological filtration, good aeration and circulation, the right balance of plants, an appropriate fish load, and control of excess nutrients and debris. A UV clarifier can control suspended algae. Unlike a pool, a pond is kept clear by biology working correctly, not by chemicals.

A koi pond typically needs a liner or structural shell, a pump to circulate the water, mechanical and biological filtration to handle waste and clarify the water, aeration to keep oxygen levels healthy for fish, and often a UV clarifier to control green water. Waterfalls and streams add both beauty and valuable aeration.

Yes, and a healthy ecosystem pond is designed for both. Plants provide shade, oxygen, filtration, and cover, while fish add life and movement. The balance matters: the planting, the fish load, and the filtration are sized together so the pond stays healthy. Koi will graze on some plants, which an experienced pond builder plans for.

Koi need enough depth to be healthy, to regulate temperature, and to be protected from predators, so koi ponds are built deeper than ornamental water gardens. The exact depth depends on the climate and the design. A pond builder sets the depth and profile to suit koi and local conditions rather than to a single fixed number.

An ecosystem pond is a pond designed to function as a balanced, largely self-sustaining natural system. Circulation, biological filtration, aquatic plants, beneficial bacteria, fish, and rock and gravel all work together so the pond stays healthy and clear with modest intervention. It is the modern approach to building a pond that thrives rather than struggles.

A well-designed ecosystem pond is relatively low maintenance, because the biology does much of the work. Routine care includes seasonal cleanouts, managing debris and plants, monitoring the fish and water, and maintaining the pump and filtration. A pond that was designed and built correctly is far easier to care for than one that was not.

Yes. A pool and a koi pond or waterscape can be designed together so the whole backyard reads as one connected landscape, often with a waterfall or stream linking the elements visually while the systems remain separate. Designing them together from the start produces a far more cohesive result than adding one later.

Choose a builder on substance, not the lowest bid. Look for proper licensing and insurance, a real body of completed work, a clear and itemized proposal, a transparent contract and schedule, and good communication. Favor a design-build company that engineers and constructs with one team, so one company is accountable for the whole result. The cheapest bid is often the one missing scope.

Ask whether they are licensed and insured, whether they design and build with their own team or subcontract, how they handle permits and inspections, whether the price is fixed and itemized, what the schedule looks like and how delays are handled, what is and is not included, how change orders work, and what happens for service and warranty after the pool is finished.

A design-build company designs, engineers, and constructs the pool with one integrated team instead of handing a design to a separate builder. It matters because it removes the gap where quality and accountability are usually lost: the people who engineered the pool are the people building it, the proposal matches the finished pool, and there is a single company responsible from first sketch to final water.

Ideally, yes. When one company designs and builds, the design is grounded in what will actually be constructed, the fixed proposal reflects the real project, and there is no finger-pointing between a designer and a separate builder. That single line of accountability is the core advantage of the design-build model that WETYR Pools is built on.
