  |   Health & Wellness, Hot Tub Tips   |   12 Comments

Don’t worry, it’s not that hard to care for your hot tub

Owning your own personal hot tub is a luxury that provides better health, less stress, and a lot of fun. It is something you can enjoy every evening as part of your unwinding routine or just whenever you feel a little stressed.


Some people worry that hot tubs are difficult to maintain – this is not the case at all. In order to keep your hot tub in perfect condition, you simply need to perform a few easy maintenance tasks on a regular basis. Spending a few quick minutes on hot tub maintenance will increase your enjoyment and add years to the life of your spa.

Sanitize Regularly

Keeping your hot tub properly sanitized will prevent any sort of unwanted contaminents. Granular chlorine or bromine are generally the best sanitizers. Which one you decide on depends largely on how you use your spa and the water chemistry in your area. Your Authorized Bullfrog Spa Dealer can help you decide. Maintaining the sanitizer levels in your spa is easy. Simply check periodically to make sure levels are within acceptable limits with a test strip. Then add sanitizer when needed. It is also recommended to oxidize your hot tub roughly weekly to help remove oils, hair sprays, and other substances. Including an ozone generator on your spa can greatly increase the length of time needed between sanitation treatments

Clean Filters

To keep your hot tub in great condition, filters should be cleaned about once a month, depending on usage. Remove the filters and clean by spraying them off with a hose and nozzle or other high pressure water stream. Work each pleat from top to bottom. If filters start to accumulate oils from suntan lotions or normal body oils you may want to soak filter in warm water and an approved spa filter cleaning agent prior to spraying.

Drain, Clean and Refill

Hot tub water will not stay clean forever, even with proper chemical use. It is best to drain your hot tub approximately every 3 months or so. You may drain a little less or more often based on how often you use your hot tub. Over time it is normal for some chemicals, oils, and residues to build up. You likely won’t notice this; however, it’s a good practice to replace the water from time to time to be sure it stays fresh.

Maintain Your Hot Tub Cover

Hot tub covers are essential. They keep heat in and debris out, and provide greater safety. Over the life of your spa you will need one or two replacement hot tub covers. However, you can greatly improve the life and performance of your spa cover by cleaning it periodically. Using an approved spa cover protectant will help it withstand the elements. It’s easy, much like applying Armorall to the dash of your car.

    Hello, we have your Bullfrog Series I model 562. It is 2 years old so we think it may be time for new filters. Do you carry those in stock and how much are they? (ours takes 2)

    We are keeping our Bullfrog in operation all year now. Today’s low temperature is indicated to be 7 degrees and at the level for the next several days here in Ohio. I placed an outdoor wireless thermometer in the area where the pumps and heater are. The outside air temp this morning is 17 degrees and the temp in the area where I have the hot tube temp is 25 degrees. Since the spas are built in Utah do you recommend additional insulation be used to prevent the circulation area from becoming so cold the water in the lines freezes?

    • Bullfrog Spas | Dec 14, 2016 at 9:54 am

      From our service team: It actually gets much colder than this in Utah and many areas where we have operating spas. There should be no need to put extra insulation in the equipment area. The spa should be running twice a day during the filtration cycles so it is moving water and heating the water at that time. You may consider using Ready Mode to ensure regular heating during extreme cold. We have our spas all over the US and Canada and have not had one freeze due to cold temps unless the spa is completely shut down for days.

    The water pump on my bullfrog spa went out and its two weeks before I can get a service appointment. It’s November and freezing tempatures at nigh. what do I need to do to make sure I don’t get freezing damage before I can get the pump fixed?

    • Bullfrog Spas | Nov 20, 2017 at 10:23 am

      Kelly, so sorry to hear this. First, explain the freezing risk to your Authorized Bullfrog Spas dealership and they should expedite their service. Second, if they can’t expedite your service you can add additional temporary insulation to the equipment compartment by placing moving blankets inside. If you have any trouble whatsoever getting service in a timely manner contact our service team at or call us at 801-565-8111.

    I have a major complaint! I just bought a new A8l Bullfrog hot tub in Wisconsin 3 months ago. Now that the tempurate is in the 30’s my hot tub won’t hold temperature. It is set at 103 and when I open the cover it is at temp but with in 20 minutes of use the temp is down to 100! It won’t hold temp. Called dealer and they said the standard 4KW heater is known not to hold temp in the cold and that I should spend the $400 bucks for a 5.5 KW rated heater. So after spending $14,000, I have a hot tub that can’t perform in a typical Wisconsin winter day. That is just not right! Is this known by Bullfrog? I’ve owned several hot tub brands in the past and have never had this problem. I’m extremely disappointed and should not have to spend more money to get the tub to perform to specification in Wisconsin.

      We are sorry you are having an issue with the spa cooling down, we rarely see this and there are several factors that can cause heat loss. We want you to be happy with your purchase which is why we will be sending the 5.5kw heater to the local dealer and have them install it at no charge. The local dealer has been made aware he will reach to you when the heater arrives.

    I am considering purchasing and installing a Bull Frog Spa Hot Tub Model A8L. However, I want to ensure that the deck that i will constructing is strong enough to support the weight of a full tub of water and seven (7) adults. Therefore, can you please advise me what is the estimated weight that will need to be supported. Further, does Bull Frog Spas have any “construction specifications” that should be used in building the supporting deck, if so, please provide them to me. I look forward to hearing from you.

      Hi Marcel,

      You can find this answer by going to the A8L product page at our site located at this URL:
      Scroll down and click on the “Specifications” tab. There you will find the maximum filled weight of the spa, the spa dimensions, how much water it holds, and other specifications that you might find helpful.
