Drain and refill hot tub

Difficulty: moderateTime: 120 minsEst. Cost: $10 - $40

Why it matters

Hot tub water accumulates total dissolved solids over time that chemicals can no longer balance. Skin irritation, cloudy water, and foam are signs the water is exhausted. Fresh water restores chemical effectiveness.

Stop forgetting to do this.
