    Frequently Asked Questions

    • What chemicals do I need to maintain a hot tub?

      Essential hot tub chemicals include: (1) sanitizer (HTH spa™ Bromine Tablets or HTH spa™ Clear Chlorinating Sanitizer), (2) non-chlorine shock oxidizer, (3) pH balancers, (4) alkalinity increaser, and (5) HTH spa™ Test Strips. Add specialty products as needed: clarifier for cloudy water, defoamer for foam, scale preventer to help prevent mineral buildup, filter cleaner to remove buildup from the filter, and enzyme cleaner to break down oils and other organic contaminants.

    • How often should I change my hot tub water?

      Change hot tub water every 3–4 months under normal use (1–2 people, several times per week). Heavy use, foam, persistent cloudiness, or water that won't balance despite chemical treatment are all signs it is time for a fresh fill. Before refilling, clean the shell and flush the plumbing. HTH spa™ 30-Day Triple Action Cleaner and HTH spa™ Jet Clean Max can also be incorporated into your spa-care routine according to their product labels.

    • What is a complete hot tub startup chemical list?

      To start fresh hot tub water: 1) HTH spa™ Test Strips. 2) HTH spa™ Alkalinity Up. 3) HTH spa™ pH Up or HTH spa™ pH Down. 4) HTH spa™ Bromine Reserve + HTH spa™ Bromine Tablets (or HTH spa™ Clear Chlorinating Sanitizer). 5) HTH spa™ Non-Chlorine Shock Oxidizer. 6) HTH spa™ Scale Preventer. Optional: HTH spa™ Enzyme Cleaner, HTH spa™ Metal Out, and HTH spa™ Clarifier for ongoing maintenance.

    • How do I close my hot tub for the winter?

      If winterizing (not using): 1) Shock and balance water one final time. 2) Run jets for 20 minutes with HTH spa™ Jet Clean Max according to label directions. 3) Drain completely. 4) Use a wet/dry vac to remove water from all jets and plumbing. 5) Remove and clean the filter. 6) Leave the cover on but slightly ajar for airflow. 7) Disconnect and protect the heater and pump per manufacturer's instructions. Never leave water in lines in freezing temperatures.

    • How much does it cost to maintain a hot tub with chemicals per month?

      Monthly chemical costs for a typical hot tub (300–500 gallons, 2–4 users, used 2–3x per week) average $25–$75 per month depending on products used and water quality. Main recurring costs: bromine tablets, non-chlorine shock, pH adjusters, and filter cleaner. Testing regularly and addressing small imbalances immediately prevents costly remediation treatments.

    • What happens if I don't change my hot tub water for too long?

      Over time, TDS (total dissolved solids) accumulates from dissolved chemicals, minerals, and bather waste. When TDS is too high, water becomes impossible to balance correctly — chemicals stop working as expected, sanitizer is less effective, water may look dull, and scale/foam problems escalate. Drain and refill every 3–4 months regardless of how balanced the water appears.

    • Can I use a hot tub during cold weather?

      Yes — hot tubs are designed for year-round use. In cold weather, maintain water chemistry as normal, keep the cover on when not in use to retain heat and prevent chemical evaporation, and ensure the freeze protection feature on your hot tub is functioning. Check that water flow through jets does not freeze in exposed plumbing during extreme cold snaps.

    • How do I purge a hot tub before draining?

      Before draining, use a hot tub pipe and jet cleanser with the jets running at full speed for the label-directed amount of time. This flushes biofilm, scale, and organic buildup from the internal plumbing — residue that contributes to foam, odor, and water quality problems in the next fill. Drain immediately after purging while the loosened debris is still suspended. HTH spa™ Jet Clean Max and HTH spa™ 30-Day Triple Action Cleaner can also be incorporated into your spa-care routine according to their product labels.
