How much does a full St.Lucia AirJet (2-3 person) weigh?
Its 160 gallons of water alone weigh about 1,334 lb. The tub itself is light (roughly 50 to 90 lb), so filled with water and 3 bathers it lands near 1,964 lb, almost all of it water. Either way, the water is the heavy part. Work out any tub on the filled weight calculator.
Keep the water right
A 160 gallon tub doses in small amounts, so a kitchen scale and small additions beat eyeballing it. Test, balance alkalinity then pH then sanitizer, and use the dosing calculator sized for this tub. Start with test strips and a chemical kit.
