Gaius Maecenas was a wealthy imperial advisor to Augustus and considered one of the first patrons of arts. Many health clubs, fitness centers, and private clubs have pools used mostly for exercise or recreation.
Factors like rain, chlorine, and heavy use can alter pH levels, which are measured using a scale of 0 to 14, with 0 being the most acidic and 14 being the most alkaline. It’s critical to keep water levels around 7.2 to 7.8 to avoid skin and eye irritation.
They rarely exceed 6 m2 and are typically 1 m deep, restricted by the availability of the raw sheet sizes . There is often a mid-depth seating or lounging system, and contoured lounger style reclining seats are common. Upmarket spas include various jet nozzles (massage, pulsating, etc.), a drinks tray, lights, LCD flat-screen TV sets and other features that make the pool a recreation center.

Many pools are incorporated in a redwood or simulated wood surround, and are termed “portable” as they may be placed on a patio rather than sunken into a permanent location.
Though a cover decreases the total amount of solar heat absorbed by the pool, the cover eliminates heat loss due to evaporation and reduces heat loss at night through its insulating properties. This resort is located at 4200 m AMSL and has two indoor swimming pools and one outdoor swimming pool, all filled with water from hot springs. When it comes to finding relief from the heat and having fun, few options are as easy and versatile as an inflatable pool.
Reviewers love the amount of space and the strong and sturdy PVC material it’s made of. Swimming pool heating costs can be significantly reduced by using a pool cover. Use of a pool cover intex purespa also can help reduce the amount of chemicals (chlorine, etc.) required by the pool. Outdoor pools gain heat from the sun, absorbing 75–85% of the solar energy striking the pool surface.
Especially the selection of unsuitable stainless steels can cause problems with stress corrosion cracking. Pools also present a risk of death due to drowning, particularly in young children. In regions where residential pools are common, drowning is a major intex frame pool cause of childhood death. As a precaution, many jurisdictions require that residential pools be enclosed with fencing to restrict unauthorized access. The evidence for floating alarms and window/door alarms to reduce the risk of drowning is poor.
