  1. Too Much Chlorine in Your Hot Tub? Here’s How to Fix It

    Leave a Comment

    You only need a small amount of chlorine to successfully sanitize your spa, so it’s possible to overdo it if you’re not careful. Too much chlorine can damage your hot tub and irritate your skin, eyes and lungs. Thankfully, reducing the chlorine levels in your hot tub is very easy to do. In fact, you may not even have to do anything at all.

    How to Figure Out If You Have Too Much Chlorine in Your Hot Tub

    Some people assume that their chlorine levels are too high without actually checking. They think they can detect high levels of chlorine by noticing a specific smell, skin irritation, a change in their hair color or eye discomfort. But in reality, these sensations usually aren’t caused by chlorine at all. It’s much more likely that other substances, like chloramines, pH and copper, cause these changes in the water.

    The only way to truly know if you have too much chlorine in your hot tub is to test the water with chlorine test strips. The Center for Disease Control and Prevention (CDC) recommends that chlorine levels be between 1.0 and 3.0 ppm for safe hot tub use. You’ll want to add or reduce chlorine if the tests strips read that your water is above or below this range.

    How to Reduce Chlorine Levels in Your Hot Tub

    Let the Hot Tub Reduce Chlorine Levels on its Own

    If your chlorine levels are higher than 3 ppm and you don’t need to use the hot tub any time soon, you don’t have to do anything to reduce your levels. Just don’t use the hot tub for a day or so and refrain from adding any more chlorine. Eventually, the chlorine will drop to safe levels on its own. To speed up this process, you can run your jets and remove the hot tub cover, as direct sunlight can help to deplete chlorine. It doesn’t get much easier than that!

    Refill Your Spa with Fresh Water

    Another simple way to reduce your chlorine levels is by draining your spa. After you refill it with fresh water, you can add the required chemicals again by carefully testing the water. If you need help figuring out the correct amount to chlorine to add to your ThermoSpas® hot tub water, feel free to give our customer care representatives a call at 1-800-876-0158. We would love to help.

    Use a Chlorine Neutralizer

    If your chlorine levels are very high after a shock or after adding too many chlorinating granules and you need to use your hot tub soon, you can use a chlorine neutralizer. We recommend letting the chlorine levels deplete naturally with the methods above if possible. But if you must deplete levels quickly, you can use sodium thiosulfate. Make sure to add the neutralizer gradually and carefully follow directions and dosages based on your test strip reading.

    We hope these tips help you to get the chlorine in your hot tub water back to safe levels again. After you’ve balanced out your chlorine levels, make sure to check your other chemical levels too. A rise or fall in chlorine levels can affect the other chemical levels.

  2. What Are the White Flakes in My Hot Tub Water?

    Leave a Comment

    Regularly cleaning and sanitizing your hot tub helps to keep strange things from happening, like seeing white flakes in your hot tub water. White flakes are usually caused by calcium scale deposits. But they may also be a sign that your hot tub contains white water mold, which is an overgrowth of biofilm. Either way, you’ll want to get rid of them. As long as you consistently maintain your hot tub with a simple and quick cleaning routine, you shouldn’t run into these problems. But if you do, we’re here to help.

    How to Find Out if the White Flakes Are Caused By Calcium or Biofilm

    To determine whether the flakes are a result of calcium scale deposits or biofilm, you need to find out if they are organic or inorganic. All you have to do to figure this out is fill up 8 ounces of spa water with the flakes inside. Then, pour 20 drops of bleach or liquid chlorine in the water you collected. Gently stir the water and sanitizer, and wait for 30 minutes.

    If the flakes remain in the water after 30 minutes, they are most likely caused by calcium scale deposits. If they aren’t there anymore, they are probably a result of biofilm.

    How To Get Rid of White Flakes Caused by Calcium Scale Deposits

    Good news! Getting rid of calcium scale deposits is easy. Just follow the two simple steps below.

    • First, make sure to keep your pH alkalinity properly balanced. Scale begins to form when your pH is too high.

    • Then, use a scale preventer, like ThermoSpas Spa Stain & Scale Preventer, every week. If you have a high mineral content, add 4 ounces per 100 gallons on initial fill and 2 ounces per 100 gallons weekly. For water with a low mineral content, add 2 ounces per 100 gallons on initial fill and 1 ounce per 100 gallons weekly.

    The scale preventer will work to break down the existing particles, peeling the scale away from your spa. Both balancing your spa’s chemicals and using a scale inhibitor should also keep this problem from happening again.

    How to Prevent & Get Rid of White Flakes Cause by White Water Mold & Biofilm

    When compared to calcium scale deposits, biofilm is a tougher and more serious issue. As long as you take proper care of your hot tub, you shouldn’t run into a biofilm problem. Biofilm usually forms as a result of a spa that hasn’t been used for a while or improper cleaning techniques when the spa is being used. If you do get biofilm, take the steps that are detailed in this blog post and make sure to start following a simple and regular cleaning schedule.

    As long as you take care of your hot tub, you shouldn’t have to deal with white flakes of any kind in your water. Maintaining your spa is easy to do and takes very little time out of your day. If you have any more questions about white flakes in your ThermoSpas® hot tub, feel free to contact our customer service representatives today by calling 1-800-876-0158. We would love to help you make your spa water clear again.

  3. What To Do With Your Hot Tub While You’re On Vacation

    Leave a Comment

    We’d all like to take our hot tub with us when on vacation. But unfortunately, it’s not really practical. Since you can’t take your hot tub with you, we’re here to help you prepare your hot tub before you go out of town. This way, it will be ready for you to jump right back into when you get home, saving you time and energy. All you have to do is take a few minutes to follow the simple steps below.

    Test the Chemical Balance

    Before leaving your hot tub, you’ll want to analyze the chemical balance to determine if the properties are too alkaline or too acidic. By maintaining your water chemistry, you’ll be minimizing the amount of bacteria that survives in the water while you’re gone.

    Thankfully, testing your chemical balance and then adding the proper chemicals is easy! Testing strip instructions vary in their steps, so read your bottle’s instructions carefully. That being said, the basic procedure should be the same. Here are the simple general steps:

    • Before testing, turn your bubbling system or jets on for 1 to 2 minutes and let the water circulate.
    • After your water has moved around, use a clean plastic bucket to take a sample of the water.
    • Dip your test pad into the bucket’s water. Let it sit in the water for about 15 seconds. Try not to place your fingers on the pad because this may contaminate the test pad and give you a false reading.
    • Remove the test strip from the bucket and shake off any excess water that may still be on the strip.
    • The strip’s pad should change color. Compare this color to your bottle’s testing chart.
    • The testing chart will help you understand your water’s chemistry. By looking at the color, you should be able to identify if it’s too acidic or alkaline.
    • Once you’ve identified the water’s chemical levels, you can adjust them by adding the appropriate chemicals.

    Consider Using ThermoClear

    ThermoClear™ is one of the simplest ways to purify your hot tub water, especially when you’re not using your hot tub. If you have a 300 to 400 gallon spa, all you have to do is add 2 ounces of spa activator to the cartridge before you leave for vacation. It’s as easy as that. You should add 2 ounces of spa activator to your cartridge every week while you’re not using your hot tub. If you’re going to be on vacation for longer than a week, ask a neighbor to add the spa activator for you.

    While you’re gone, the spa activator will work to reduce scum lines, minimize foam, keep your water clear and enhance the efficiency of your Ozonator. With ThermoClear, you won’t have to worry about your spa being clean when you get back.

    Turn the Temperature Down

    Usually, you want to keep your hot tub at a steady temperature to help save energy. If you’re going on vacation, however, and aren’t going to use your hot tub for a while, it’s best to keep your temperature about 15 degrees lower than normal.  This way, you’ll save energy and money.

    ThermoSpas® hot tubs feature an economy mode, which you should turn on before you go out of town. It’s the easiest and most efficient way to save energy with your hot tub while you’re not using it. While your hot tub is in economy mode, its water temperature will automatically lower until it is 15 degrees cooler than the set temperature. When you get back home, all you have to do is set your hot tub back to standard mode. The water temperature will then rise back to its original setting.

    Securely Lock Your Cover

    Though it’s always best to lock your hot tub covers after use, it can be easy to forget sometimes. Before you leave, double check that your hot tub cover is securely locked in place. Gently tug on the strap to make sure it doesn’t come loose. Then, try moving your hot tub cover to check if the straps need tightening.

    A tightly secured hot tub cover will help keep your hot tub safe from outside debris, weather and bacteria. High quality hot tub covers also help insulate your hot tub, so that your hot tub will be using less energy while you’re out of town.

    We hope these steps help to make your vacation preparation a little bit easier. If you have any more questions about hot tub maintenance, feel free to give our customer service representatives a call at 1-800-876-0158. We’d love to help.

  4. Preparing Your Hot Tub for Winter

    Leave a Comment

    Soaking in your hot tub during a snowy winter evening is a beautiful and relaxing experience. You keep warm in the heated hot tub water while ice-cold snow surrounds you, steam rising up. It’s a picturesque moment.

    Even if it doesn’t snow where you live during the winter, a hot tub helps you to keep toasty on the chilly evenings. We suggest you use your hot tub in every season, including winter.

    We have put together some steps you should take to prepare your spa for winter, whether you’re planning to use it or not. If you’re not planning to use your hot tub regularly during the freezing cold winter or are going out of town, you’ll have to follow simple steps to winterize and close your spa to avoid freezing damage.

    Replace Your Hot Tub Cover if You Need To

    You always want to make sure your hot tub is well covered up, but it’s especially important to do during the winter. A good quality hot tub cover will keep your water warm and keep snow and rain outside. If your cover is sagging or bowed, you’ll want to replace it before winter, even if you’re not planning to use your hot tub. Puddles of rain or snow can form on bowed or sagging hot tub covers, causing them to sag even more and possibly even crack.

    Make sure to clean and condition your hot tub cover regularly during winter, and always push water off of your cover after rainfall, snowfall or your time in the hot tub.

    Drain, Inspect and Clean Your Hot Tub

    Whether you plan to close your hot tub for the winter months or not, you’ll want to drain and clean it. You’ll be creating a safe and clean environment for all of the relaxation you’ll be having throughout the winter months, or for when you begin using your hot tub again. It’s better to clean your hot tub before the cold winter months than during.

    To drain your hot tub, follow these simple steps:

    1. Close all therapy control valves and open all jets.

    2. Then, turn the spa breaker off.

    3. Now it’s time to drain the water out. We recommend doing this with a submersible pump. If you don’t have one of those, you can attach a garden hose to the hose spigot, which is on the primary water pump within the spa interior.

    4. Finally, open the spigot to allow your spa to drain.

    When your spa is drained of all water, inspect the jets, pumps, valves, pipes and filters for any damage and built up dirt. You should also check your shell and the mechanics behind the panels of your tub for any cracks or leaks. If you do find any damaged parts, you can replace them or contact us. Our representatives are available for service and repairs year-round.

    After you have inspected your hot tub for any problems, dry it off and clean the shell’s surface with an all-purpose cleaner. Then, apply ThermoGloss to your shell to polish and protect its acrylic surface. Next, clean your hot tub filters to ensure that they work effectively during the winter. Finally, if you plan to use your hot tub during winter, detach your hose, close the spigot tightly and refill your hot tub with fresh, clean water. When you’re spa is filled up to normal operating levels, turn your spa’s circuit breaker back on.

    If you’re not going to use your hot tub regularly in the winter, skip down to the Winterize Your Spa section of the article.

    Check Up on Your Hot Tub Regularly if You’re Using It

    The winter season is the perfect time to use your hot tub regularly because it keeps you warm! If you’re planning to use your hot tub during the winter (which we hope you do), it’s important check the water temperature everyday to make sure the heater is working properly. If you detect a problem, contact ThermoSpas’ Customer Care department right away.

    If your hot tub is not working properly or a power failure occurs during freezing cold weather, you’ll need to winterize your spa by taking the steps below. You can also contact our service department to come fix your hot tub. Just give us a call at 1-800-876-0158 to make an appointment. While you’re waiting for service, you’ll want to make sure your hot tub doesn’t freeze. A good trick is to place the submersible pump in the hot tub and let it circulate the water so that it doesn’t freeze up.

    Winterize Your Spa if You’re Not Using It

    Many people go out of town during the winter months and won’t be using their hot tub regularly. If this is the case for you, you will want to winterize your hot tub. It’s an easy, but important process.

    If you don’t want to winterize your hot tub yourself, ThermoSpas can do it for you! Our service department can  You can give us a call at 1-800-876-0158 to make an appointment. In

    Follow these simple steps to winterize your spa after you’re already drained and cleaned it:

    1. Remove the cabinet panel in front of the spa’s equipment compartment.

    2. Open the hose spigot, if you haven’t already, to drain any leftover water and keep it open. You can find the hose spigot near the primary pump.

    3. View your owner’s manual to locate the heater. Then, turn the heater unions counter-clockwise to open them at both ends.

    4. Use a canister-type wet vacuum to clear all of the water from the water pumps suction and return lines.

      1. You must use a canister-type wet vacuum to ensure that the lines are emptied of all remaining water.

    5. Remove the drain plugs from all of the water pumps.

    6. After all of the water has been drained from the water pumps, replace the pump plugs.

    7. Turn the heater unions on the heater clockwise to reconnect them. Turn until tight. Make sure the O-ring gaskets are sealed properly so as to not pinch O-rings. Do not over-tighten.

    8. Replace the cabinet panel in front of the spa’s equipment compartment.

    9. Turn on the spa circuit breaker.

    10. Turn on the blower to expel water from the plumbing and air channels.

    11. Turn off the spa circuit breaker.

    12. Remove the insulated hot tub cover from the spa.

    13. At each fitting, use a wet vacuum to assist in removing any remaining water in the fittings, water lines and spa shell.

    14. Sponge out any remaining water from the spa shell.

    15. Replace your hot tub cover and make sure that rain water and/or snow is not entering the spa through the cover.
