Frequently Asked Questions for Spa Owners

Hot Tub Maintenance

How do I clean my filters?

Every 3 to 6 weeks, depending on frequency of use and number of bathers, spray the filter off with a high-pressure garden hose attachment. Depending on use, a de-greaser or de-scaler is recommended every 4-6 months. Refer to the owner’s manual.

How do I maintain my spa cover?

Your spa cover is either a Patio Performance fabric cover or a standard vinyl cover and is warranted by its manufacturer. Although basic instructions are provided below, it is important that you refer to manufacturer-provided information that came with the cover. Additionally, your Authorized Dealer may provide more detailed information on caring for your spa cover and what to do to protect its warranty.

Cleaning a Patio Performance™ Fabric Spa Cover

The best way to keep your Patio Performance fabric hot tub cover looking its best and avoiding more intensive cleaning is to simply brush off dust and debris regularly before it becomes embedded and spot clean any stains that may occur as soon as possible.

To spot clean more difficult stains on your cover, use a soapy solution of lukewarm water and mild soap and dab with a cloth or sponge. Rinse thoroughly with clean water and air dry. For stubborn stains you may also use a fabric spot remover according to instructions. Always test spot removers for colorfastness first.

If regular maintenance and cleaning is not observed, especially in humid climates, it is possible for mildew to attach itself to foreign substances that are not cleaned from the fabric. To remove mildew, prepare a mild solution of 1/2 cup of bleach and a tablespoon of mild soap in a gallon of water. Spray the area thoroughly and allow to soak in. Wipe away with a clean cloth. Rinse thoroughly and allow to air dry.

Cleaning a Vinyl Spa Cover

At least monthly, clean the spa cover following the directions below.

  • Step 1: Remove the cover and lay it down on a flat, clean surface near a garden hose.
  • Step 2: Rinse the cover to remove any loose debris.
  • Step 3: Clean the top (vinyl) of the cover with a mild solution of dishwashing soap and a soft bristle brush. Using a gentle circular motion, scrub the cover, careful to not let any of the cover dry before rinsing with water.
  • Step 4: Rinse the cover thoroughly and dry with a clean cloth.
  • Step 5: Use saddle soap (never a petroleum-based product) to condition the cover per the manufacturer’s instructions.
  • Step 6: Wipe and rinse any dirt from the bottom of the cover.
  • Step 7: Replace the cover and secure the locks.
  • NOTE: To remove tree sap, use lighter fluid (the type used in cigarette lighters). Use sparingly. Immediately, apply saddle soap to the area.

How do I clean and protect spa pillows?

Regularly clean all pillows with mild soap, water, and a clean cloth. Monthly, treat pillows using a non-petroleum-based product such as 303 Protectant. This will maintain water resistance and luster of the product.

IMPORTANT: Remove the pillows when shocking the spa or when sanitizer levels are high. Leave cover open for at least 30 minutes after shocking to ensure pillows are not affected.

NOTE: Pillow discoloration is caused by accelerated by high sanitizer use and is not covered under the Bullfrog Spa Warranties.

How do I clean the hot tub shell?

Refer to your local Authorized Bullfrog Spa Dealer for gel gloss or any shell cleaner that will not interfere with water chemistry. Recommended at the time of each spa draining.

For normal cleaning, use a mild dishwashing soap such as Ivory® liquid or a window cleaner such as Windex®. For stubborn stains, use a mild liquid cleaner such as Softscrub® or a mild detergent such as Spic And Span®. To apply these cleaners, use a soft, damp cloth or sponge. Rinse well and dry with a clean cloth. To clean hard water stains, remove light scratches and protect your spa shell, contact your authorized Bullfrog Spa dealer.

With normal use of the spa, oils, lotions, and hair spray will build up on the surface of the water. This can leave a residue line around the perimeter. This can be easily removed using a spa surface cleaner or its equivalent. Avoid using cleaning agents that leave suds in the water.

WARNING: Never allow your spa surface to be exposed to alcohol, acetone (nail polish remover), nail polish, dry cleaning solution, lacquer thinners, gasoline, pine oil, abrasive cleaners, or any other household chemicals other than those listed. These chemicals can void the warranty.

How do I vacuum the spa?

Debris from wind, trees, and users will occasionally accumulate on the bottom of the spa. The filtration system will remove the smaller debris; however, debris that is too large or heavy will have to be removed by a spa vacuum. If you do not have a spa vacuum, contact your Authorized Bullfrog Spa Dealer.

How do I maintain my JetPaks?

For optimum care, each time the spa water is changed, remove all JetPaks. Clean the plumbing (piping for Sport X or back manifold area on A Series, R Series or STIL spas) with a spa surface cleaner and a long, soft bristle brush. For cleaning the JetPak acrylic surface, refer to Spa Shell Care.

How do I winterize my spa?

Winterization of your spa is not generally necessary unless you plan to be away for an extended period of time. When you are not planning to use the spa for six or more weeks, or when someone is not able to maintain the spa on a weekly basis, you should winterize the spa. To winterize, follow these steps:

WARNING: Prior to winterizing your spa, it will be necessary to Super Sanitize the spa water as per the instructions in the Water Chemistry section. This procedure will help prevent the growth of bacteria, algae and fungi in any areas of plumbing that may not be fully free of water after you drain your spa for its period of winterization.

  • Step 1: Drain the water.Step 1: Drain the water.
    NOTE: For Sport X Spas or Bullfrog Spas made before 2013 skip to Step 4
  • Step 2: For A or R Series spas. Open all lower valves on the JetPaks to allow the water to drain form each JetPak as you drain the spa. Once the water is completely out of the spa then close each JetPak valve before starting step 3.
  • Step 3: Use a wet shop vacuum to vacuum the plumbing lines by placing the vacuum nozzle over each of the lower jet faces in the spa. Lower jets are any at or below the bench seat area.
  • Step 4: Remove the drain plug from the pump(s), loosen all PVC pipe unions, and pump air-bleed valves in the equipment compartment. Replace plugs on heater pump. Do not replace the plugs on Pump 2. Tighten the unions or close the air-bleed valves until the spa is de-winterized.
  • Step 5: Clean the entire spa.
  • Step 6: Remove filter cartridge(s) and clean. Do not reinstall until they are completely dry.
  • Step 7: Secure the cover to the spa utilizing the tie downs and locking system. In areas where heavy snow is anticipated, place a large piece of plywood (or its equivalent) on top of the spa cover to assist in supporting the cover with the added weight of the snow. Remove snow off the cover following each snow storm.

WARNING: To avoid water from becoming trapped between the floor suction fitting and the filter pipe . Use a wet/dry vacuum to remove the remaining water out of pipe by placing the vacuum end over the filter hole. In a two-pump spa, first plug off one filter using a tennis ball then vacuum out the water. Or pour ½-1 gallons (5-9 liters) of RV antifreeze into the filter hole. NOTE: RV antifreeze is nontoxic and does not require evacuation at start up.

Spa De-Winterization

To de-winterize the spa, reverse the Winterization procedure. Refill to the water level mark.

WARNING: Whenever refilling the spa, it will be necessary to Super Sanitize the new spa water. Instructions are found in your Owner's Manual.


How do I program the spa controls?

Refer to the start up instructions in your owners manual.

Why does my GFCI keep tripping?

The neutral wire from the spa to the breaker box must be wired into the breaker itself and not the bus bar. This is because it is not a dedicated 240v spa. If the neutral is wired to the bus bar, the breaker will instantly trip at power up.

Refer to wiring diagram.

Why is my spa overheating?

If the spa is located in an area that is experiencing hot weather, it is normal to have the spa water temperature rise. Keep spa in economy mode, minimize filtration hours and open lid for heat escape. Never leave a spa unattended while the cover is open do to safety issues.

If OHH is displayed on the control panel, this means that the thermometer has detected spa water temperature above 110 degree F.

My spa won’t work after a drain and fill, how do I fix this?

Alternate between high and low speed on the pump at least 6-7 times to purge the system.

The wet-end of the pump has a bleed valve, loosen this until all the air escapes and water starts to drip out or, loosen the union on the pump to let the air out until you see water. Do not attempt this while the spa pump is running. If this does not resolve the problem, please contact your authorized Bullfrog Spa Dealer.

My spa is not level, is this a problem?

If your spa’s pad is slightly sloped it will not affect the performance of the spa or its structure, however, there should be no dips, sags, or unevenness in the pad. Most patios are built to slope away from the house for drainage purposes. There should be no more than a ½” (1.27cm) slope in an 8‘ (2.44m) run. Do not use shims to level the spa, this could create tension on the spa shell which might result in damaging your spa.

How do I move my spa?

A cart or dolly that can support at least 900 pounds is the best way to move your spa. Carpets can also be used to drag a spa on most surfaces.

Attention: Do not lift the spa on the door side because the door side cannot support the weight of the spa and you may break the door.

How do I replace the Ozone purifier?

On the front of the Ozone Purifier (optional) is the indicator light. To verify that the Ozone Purifier is working properly, check to ensure that the indicator light is glowing while the filter pump is running during a period when the pump has been activated automatically.

IMPORTANT: The indicator light will not be on when any jets button has been activated manually. The light will remain off for 30 minutes thereafter.

NOTE: If the indicator light does not turn on during automatic filter pump operation, contact your authorized Bullfrog Spa dealer for service.

Water Care

What is the best sanitizing chemical to use?

As a manufacturer we do not recommend the best sanitizers to use because water varies based upon region and source (calcium, pH levels, minerals, metals, etc.). See your local Authorized Bullfrog Dealer for best service.

Do I need to keep the cover on when the spa is not in use?

Yes! Never leave a spa unattended while the cover is open due to safety issues. Also, it is recommended to keep spa covered at all times and the spa out of direct sunlight to avoid damage that may be caused by direct sunlight. Never leave an unfilled spa in the sun.

WARNING: A non-secured or improperly secured cover may pose a safety threat to children and may also cause damage or injury if blown off by wind. Always remove entire cover before using the spa.

IMPORTANT: Do not stand, sit, or place any item on the cover that could damage it. Gently remove any snow accumulations over 2” (5.08cm). Do not use any cleaners other than those recommended. Always secure the cover with all of the cover locks when not in use, whether the spa is empty or full of water. When Super Sanitizing your spa, always follow the cover care instructions provided in the Super Sanitation section.

How do I maintain my spa water in low-use or no-use periods under 6 weeks?

If the spa will not be used for at least two weeks, lower the temperature to the lowest setting of 80 F (26°C) or place in low range heat mode. Lowering the temperature will cut the cost of operation, however; you will need to adjust the temperature setting approximately 4 hours before use in order to heat the spa to 100 F (38°C).

IMPORTANT: For all no-use periods, and on a weekly basis, be sure to have someone visually check that the spa is functioning correctly and to also maintain the spa water chemistry. Not doing so may lead to corrosion, staining, and/or scaling to the spa and its equipment. During periods of freezing temperatures, a spa that has malfunctioned may be subject to damaged plumbing or equipment as a result of ice buildup within the spa. If the spa cannot be checked and maintained on a weekly basis, then consider winterizing the spa.
