4. Operation of Components
4.1 Sand Filter Pump
The included 1,600-gallon sand filter pump is essential for maintaining water clarity and hygiene. Refer to the separate pump manual for detailed operating instructions, including backwashing and rinsing procedures. The pump is designed to be used with sand or Polysphere™ filtration balls (not included).


4.2 ChemConnect Chemical Dispenser
The ChemConnect dispenser is designed to distribute pool chemicals (e.g., chlorine tablets) evenly throughout the pool water. Follow the chemical manufacturer's instructions for dosage and placement within the dispenser.
4.3 Surface Skimmer
The surface skimmer helps remove floating debris such as leaves and insects from the water surface, contributing to cleaner pool water and reducing the load on the filter pump.
5. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your Bestway Hydrium pool.
5.1 Liner Care
The pool's inner liner features a UV-resistant coating to prevent cracking and discoloration from sun exposure. Regularly inspect the liner for any signs of damage or wear. Clean the liner periodically with a soft brush and pool-safe cleaner.

5.2 Water Quality
- Filtration: Operate the sand filter pump daily for several hours to ensure proper water circulation and filtration.
- Chemical Balance: Regularly test the pool water for pH, chlorine, and alkalinity levels. Adjust chemicals as needed to maintain optimal balance, following chemical manufacturer guidelines.
- Cleaning: Skim the water surface daily. Vacuum the pool floor as necessary to remove settled debris.
5.3 Pool Cover Use
Use the provided pool cover when the pool is not in use to prevent debris from entering the water and to reduce evaporation. Ensure the cover is securely fastened.

5.4 Winterization
Since the pool is designed to stay up year-round, proper winterization is important in colder climates. Consult local pool care professionals or Bestway customer support for specific winterization procedures for your region. This typically involves balancing chemicals, lowering the water level, cleaning the pool, and properly storing or protecting the pump and other accessories.
