Place a garden hose in the filter canister and fill your spa with regular tap water about six inches from the top. If the water level is too low or too high, your spa will not operate properly.
Always fill the spa through the filter canister! Failure to do so may cause air to be trapped in the filtration system and prevent the pumps from operating properly.
Never fill your spa with soft water.
Soft water makes it impossible to maintain the proper water chemistry and may cause the water to foam, which will ultimately harm the finish of the spa and void your warranty.
