These chemical instructions are for your Softub using granular chlorine & a Spa Frog Mineral Cartridge.

  1. Completely fill the tub first. The proper level is 2” above the highest jet. VERY IMPORTANT:  After adding approximately 2”-3” of warm water, if available, turn the water source off and remove all wrinkles from the bottom of the tub. After wrinkles are removed, continue to fill until water is 2” above the highest jet. On the 300+ model, you will need to turn the water source off again once the water is 2”–3” over the seat and smooth out any wrinkles on the seat.
  2. Plug in the tub and circulate water. Check under the connections to ensure no leaks. Make sure the connectors are snugly hand tight. There is no need to tighten any further.
  3. Add 2 oz. of Spa Metal & Scale Control. (Look for Softcare Gon in your kit) Allow the tub to circulate for 30 minutes before proceeding to Step 4.
  4. Add 2 tablespoons of Granular Chlorine. This will purify the source water and establish a chlorine residual. Allow at least 30 minutes of circulation. (Your spa water will still be cool at this point. It will take between 24 and 48 hours to reach your selected temperature.)
  5. Once the Softub is at temperature, gently pull the cartridge filter off and insert the Softub Spa Frog into the hollow middle of the filter. Snap the cartridge filter back onto the intake grate. Mark on your calendar 4 months from this date as that is when the Spa Frog will need to be replaced. (Spa Frog is an optional mineral purifier that kills bacteria and assists in decreasing the amount of chlorine necessary to keep your water clean.)
  6. Check your water balance weekly with the test strips provided. Adjust the pH if necessary using either pH up to raise your pH or pH down to lower your pH. ***Very Important*** Failure to maintain the proper level of pH in your Softub could cause permanent wrinkles in your liner. This is not covered by the warranty.
  7. Periodically add a maintenance dose of Metal and Scale Control (Gon) to control scale buildup, minerals and/or metals in your Softub. If you are on well water, you may want to add a weekly dose and if you are municipal water, you may want to add a dose monthly.  Please follow directions on the bottle.
  8. Maintain a chlorine residual of at least 1-3 ppm. With the use of the Spa Frog you do not need to keep it higher than that. This will allow a more enjoyable environment for you. A good routine to follow is to add a small amount of granular chlorine each time you are finished using your tub, between 1 and 3 teaspoons depending on the size of your tub (i.e.: 140 add 1 teaspoon, 220 add 2 teaspoons, 300 add 3 teaspoons). Adjust this amount based on your usage and how your tub looks weekly. Without the Spa Frog you will need to maintain 3-5 ppm of chlorine in your tub.
  9. Within a week or two of filling your Softub, we advise taking a pint-sized water sample to your nearest pool/spa store. If you live near our Rochester, NY locations, we will happily provide this service free of charge. A professional pool/spa store will perform a comprehensive water analysis and advise you if there is anything you may need. If not having your water tested by Pettis Pools, please call the Softub Express office if any chemical is recommended that was not in your original kit or if you have any questions regarding suggestions for keeping your water clean. Do not add anything you are not sure of to your Softub.  Failure to use appropriate chemicals in your Softub will void your warranty.
  10. Depending on your water source, quite often you will need to add Calcium Hardness Increaser to your Softub.  Please check your test strip for the amount of calcium in your water within the first few days of filling your tub. The line that reads “hardness” is the one that tells you your calcium hardness level. A level of 180-400 ppm is recommended for your Softub. When adding calcium hardness increaser, only add it in 1/3 cup increments; 1/3 cup total for a 140, 2/3 cup total for a 220, and 1 cup total for a 300+ – add no sooner than 2 hours apart. Adding more than 1/3 cup at a time can cause your water to become cloudy. ***VERY IMPORTANT*** Failure to maintain the proper level of Calcium Hardness in your Softub could cause permanent wrinkles and/or bagging of your liner. This is not covered by the warranty.
  11. Always have the water circulating when adding chemicals to your Softub. This will prevent the chemicals from falling to the bottom, settling and possibly staining your liner.
  12. Do not use a floating dispenser for adding chemicals to your Softub. They do not dispense the chemicals properly due to how the tub circulates and could discolor your liner. Also, only granular chlorine is recommended for use in your Softub – since it is almost pH neutral. Do not use chlorine in liquid or tablet form.
  13. The Chlor (chlorine) that comes with your Softub is the correct chemical composition that is recommended for your Softub (Sodium Di-chloro-s-triazetrione dehydrate – 95 – 99%). Please take your chlorine bottle when you need to replace your products or better yet, call us and allow us to care for your chemical needs, or shop on-line at www.softubexpress.com.
  14. Do Not Use Bromine in your Softub. Bromine can and will discolor your liner and cause it to become brittle and crack over time. This is considered chemical abuse and will not be covered under your warranty.

Note: Use of BaquaSpa in older Softubs could cause cracking of your light lens.  If your tub serial number is 102365 or higher, this is not a concern for you.   This occurs approximately 30% of the time in older Softubs and is not covered under warranty.  Please call us with any questions and we will connect you with one of our chemical experts. Again, please do not add any chemicals to your Softub that you are unsure of or not recommended to by an authorized Softub Dealer.

Your Softub will take great care of you for years to come as long as you also take care of it. Routine maintenance is essential to keeping your Softub running properly and in good shape. Our simple routine maintenance guidelines include the following:

1. Drain your Softub every 3-4 months, even if the water still looks clear
Whether it’s a Softub or traditional hard tub, all hot tubs need to be drained periodically for the same reasons. The small body of water, combined with the body oils, perspiration, lotion and makeup bathers leave behind, as well as the chemical residuals, can saturate the water in three to four months. Warning signs that signal a change include cloudy water, excessive foaming, smelly water or difficulty maintaining water balance. We recommend saving yourself any struggle and keeping the water at its best by putting regular Softub draining on your calendar.

2. Replace your cartridge filter yearly and rinse it thoroughly once a month (or more frequently for brand new Softubs) 
Having a clean cartridge filter is a critical part of maintaining water clarity. After all, your vacuum cleaner wouldn’t pick up much dirt with a full bag. Even if the pleats of the cartridge don’t look discolored, after a year’s worth of use the fibers will start to come apart and the filter can no longer catch fine particles. For more thorough cleaning, we suggest the use of our filter cleaner, which chemically dissolves body oils off your filter cartridge for increased performance as these don’t rinse off.

3. Use Swirl Away yearly to thoroughly clean out your plumbing lines
Have you ever cut open an older plumbing line and seen the build up of bio-film and sludge? The same thing happens to hot tub plumbing lines , whether its a traditional hot tub or a Softub. Swirl Away is an impressive liquid that mimics roto-rootering your plumbing lines and will purge all buildup. Add Swirl Away the day you’re planning on draining your Softub. Drain your tub, rinse thoroughly and you’ll be good as new!

4. Use Aerospace 303 Vinyl Protectant on your tub and lid
Depending on the sun exposure your tub receives, you may need to add this product monthly or just three to four times per year. this anywhere from monthly to just 3 or 4 times a year. Even though the marine grade vinyl has a UV stabilizer built into it, a year’s worth of sitting in the sun can still have an impact. Show your tub some love and help keep it looking showroom new by simply spraying on and wiping in with a paper towel. For the ultimate in sun protection, consider purchasing a TubGuard Protective Cover.
*Never use Armor All on your Softub as it will deteriorate the seams.

5. Test your spa water at least weekly and adjust chlorine, pH, alkalinity and calcium as needed
This important step is not to be overlooked. Just like anything else, routine preventative care is the key to long-term health, and in this case, it’s the long-term health of your Softub’s interior liner. Allowing these balance parameters to drift too far outside of the recommended ranges for extended periods of time can cause permanent damage to your Softub and it is not covered under the warranty.

The great thing about owning a Softub: It can go just about anywhere! Indoors, it is safe to put a Softub anywhere where an adult can safely stand, so second floors are not off limits! Here are a few more tips to help when deciding where to place your tub inside:

  1. Your Softub should should always be placed on a structurally strong, relatively smooth and level surface (please see load specs in your owner’s manual).
  2. Consider setting up your Softub only on floors or areas that can withstand repeated exposure to water, such as tile and brick. Splashing, dripping, filling and draining are routine operations, so water spillage is going to happen. In the event of equipment failure, you may experience substantial water spillage. You should be careful that what’s underneath your spa will not warp or suffer damage in the event of a water spill. If located in a multiple floor structure, objects on the floor below should be protected in the event of a major spill.
  3. Make sure you have adequate ventilation in the room. Room humidity will exist when you are using your Softub due to the high water temperatures. Providing natural (open window or door) or forced ventilation (exhaust fan) in the room will help maintain comfort and minimize moisture exposure to the surrounding environment. In addition, you may want to consider using a dehumidifier to remove excess moisture.
  4. The underside of the Softub lid will have condensation on it that will drip down when the lid is propped up during use. You may want to consider placing a mat beneath the lid so as not to create a slippery spot on the floor.
  5. Your Softub needs a dedicated 110v 15amp circuit. Do not run any other appliances off of this circuit. A 20amp circuit is also fine. We highly suggest that you do not use an extension cord with your tub, so before you place the tub, be sure you are within reach of an outlet. If you must use an extension cord, please purchase a 12 gauge cord rated heavy duty for outdoor use in the shortest length possible. We strongly recommend that the use of an extension cord be temporary.

Your Softub can be used outdoors year-round! Yes, that means cold, snowy winters too. To help get your tub settled outside, follow these tips:

  1. Although your Softub can be placed on any surface, the area should be cleaned and debris removed prior to filling it with water. Remember that once your Softub is filled, it cannot be moved without emptying, so place it where you want it to remain until the next time you change the water. The surface should also be structurally strong, relatively level and capable of supporting your Softub (see owner’s manual for current load specs). Grass is an acceptable surface, but not for long term placement.
  2. Place your locking straps under your tub and connect them to your lid prior to filling with water. Make sure to leave yourself a small amount of excess length.
  3. It is highly recommended to use a Softub TubGuard Cover to protect your investment. This will protect your tub from the elements and keep your vinyl looking new for years to come. This is especially true if you live in areas where the sun is very strong. See accessories for options.
  4. Aerospace 303 is a vinyl protectant that will keep your Softub vinyl supple and beautiful. This should be sprayed on your tub once monthly if you live in areas where the sun is strong. It will condition the vinyl and maintain the UV protection in your tub, extending its life.
  5. During particularly windy conditions, it is prudent to use your locking straps to keep your Softub lid attached.
  6. Please do not shovel snow off your Softub. Instead brush it off for use as shoveling can rip the vinyl. Snow is a wonderful insulator, so it does not need to be removed from around your tub, except for where it can be a safety concern.
  7. When removing the lid from your Softub, if you will be resting it on an abrasive surface such as brick, concrete, or stone, it is recommended you put a towel or bath mat between the lid and the surface to protect it from scuffs and scratches. You may also want to invest in one of our handy cover lifters.
  8. It is completely acceptable and enjoyable to use your Softub outside all winter long. However, if you choose not to use it in the winter, there are some important steps you still should take to protect it from the harsh winter environment:
    • If you’re not using your Softub at all and wish to empty it and store it for the winter, make sure to bring your power pack inside to a place that remains above 50 degrees Fahrenheit. Otherwise, the coils could freeze, causing leaks and operating failure.
    • Dry the Softub out completely. Try to remove as much water as you can from the internal plumbing by putting the tub on its side and rolling it slightly in both directions. Then simply wipe the tub dry. If at all possible, leave the lid open in the sunshine for an hour or so to be sure it is dry.
    • If leaving your empty Softub outside, protect it from the elements with a travel cover or a tarp. Remember to brush off large amounts of snow.
