A frame pool is disclosed including a frame assembly and a pool liner, the frame assembly including horizontal frame members and a vertical frame member coupled together via a T-shaped joint. The T-shaped joint may be constructed of plastic to facilitate attachment and detachment to the adjacent frame members and to resist galling and corrosion. The T-shaped joint may also be relatively small to improve the appearance and water containment of the frame pool.

A frame pool includes a pool body having a space for containing liquid and a support frame for supporting the pool body. The pool body has an upper edge with a sleeve. The support frame includes an upper frame extending through the sleeve and a plurality of support members holding the upper frame in an elevated position. The upper frame includes first upper tubes, second upper tubes, and connecting tubes connecting the first upper tubes to the second upper tubes. Collars are provided within assembling ends of the first and second upper tubes. Each end of each of the connecting tubes is movably inserted into a collar located within an assembling end of a corresponding one of the upper tubes. Anti-rust coatings on the outer surfaces of the connecting tubes can be prevented from being worn and water can be sealed out of the tubes of the upper frame.

Starting platform assemblies may be provided with swimming pools for competitive and/or recreational purposes. A starting platform assembly may include a frame supporting a starting platform. Starting platform assemblies may include various combinations of optional features such as but not limited to informational panels and displays, storage areas, side handles, backstroke bars, movable mounting steps, and/or wedge anchors.

A system and method for providing a hammock for a user to rest thereon in the water of the spa. The hammock may include a proximal end with head support portion and one or more attachment means for connection to an anchor on the spa shell, and a distal end with one or more attachment means for connection to an anchor on the spa shell. One or more lateral coupling members may couple the hammock to the lateral sides of the spa, and one or more longitudinal coupling members may couple the hammock to a front side and/or back side of the spa. The longitudinal and lateral coupling members may support the hammock in the water to give the user a unique flotation experience.

Freeze-protection systems and techniques are identified, particularly for equipment of swimming pools and spas. Included within structures subject to receiving water subject to freezing are means for accommodating expanded volumes of the water as it freezes. In this manner, the expanded volumes are less likely to cause damage to the structures themselves.

The disclosure provides an outdoor device for simulating a pond ecosystem comprising a plurality of simulated ponds connected together by pipelines and including an adjusting pool, a plurality of control groups and a plurality of treatment groups with different concentrations; the plurality of control groups and the treatment groups are randomly distributed in the ponds according to a random draw method or a random allocation method, and the adjusting pool is a transfer station for water inlets and outlets of the ponds. According to the device, the plurality of control groups and treatment groups are arranged in a system, achieving a scale of a middle-scale pond ecological simulation system, which can stimulate an actual complex hydrostatic ecological system including a plurality of aquatic macrophytes, algae, zooplankton, benthos and microorganisms, and evaluate the effects of the complex ecological efficiency caused by chemical pollutants entering an actual water body.
