After a long day, you go to your jacuzzi and notice your tub water is green. What do you do now? Why would a spa be green? Hot tubs often turn green, but don't worry - we're here to help!
Green water is most common in pools because of algae, but a lack of sanitizer, high pH, high cyanuric acid level, or a combination of these things most commonly causes a hot tub.
This article explains what causes green hot tub water and how to get rid of it. We also share some tips on how to prevent green water in your spa in the future.
People are often surprised to find out that algae causes the green water in their hot tubs. There are numerous reasons why your water may turn cloudy, foamy, or green, including the following:
Keeping a hot tub clean helps you prevent:
One of the most important reasons to keep your hot tub clean is to reduce the risk of health problems.
Hot tubs can be breeding grounds for bacteria and other microorganisms, which can cause skin infections, respiratory illnesses, and other health problems.
Another reason to keep your spa clean is to avoid the buildup of foam from the hot tub, which can be caused by residue from body products.
Dirty hot tubs can develop scale, a build-up of minerals that can damage the pump, filters, and other components.
Dirty hot tubs are more likely to develop mold and mildew, which can cause staining and structural damage.
If you don't keep your hot tub clean, you may have to pay for costly repairs.
As mentioned above, scale and other build-ups can damage the pump and filters, which can be expensive to replace.
If mold and mildew are allowed to grow unchecked, they can cause extensive damage to the hot tub's shell or liner, which can be very costly to repair.
A fourth reason to keep your spa clean is that it will help to extend its lifespan.
Like any other piece of equipment, a well-maintained hot tub will last longer than one that is not.
By keeping your hot tub clean and using the right techniques, you can also prevent hot tub foam and enjoy your spa for years to come.
Depending on how bad it is, there are several ways to treat cloudy hot tub water and get rid of the green tint:
If algae causes green water, the first thing you need to do is flush the plumbing lines. This process will remove any algae that may be growing in the pipes.
To prevent foaming, ask guests to avoid using body moisturizer and perfume before entering, as these can leave residue in the water.
Turn off the pump and let the spa tub sit for 12 hours. After 12 hours, turn on the pump and let the water circulate for another 30 minutes.
If flushing the plumbing lines doesn't work, you may need to drain and refill the hot tub. It will remove all the water from the hot tub so you can start with fresh, clean water.
Even if you have a new hot tub, it's important to perform regular maintenance like turning off the pump and draining the water.
Then, open the drain valve and let the water drain out. Once the spa is empty, close the drain valve and reconnect the hose.
Using the proper chemicals, you can get rid of green water and prevent it from returning.
There are a lot of different hot tub chemicals available when it comes to choosing the right shock treatment. You can use chlorine, bromine, or even enzymes.

You can buy a hot tub that comes with a self-cleaning system. Or, you can hire a professional hot tub maintenance company to do it for you. Both options will save you time and effort in the long run.
Pink algae will make the water in our hot tubs very pink. Pink algae are not algae in any sense but are rather bacteria interacting similarly to algae. It isn't a regular occurrence in hot baths and has no easy removal.
If you discover pink tubs inside your backyard, they must be cleaned and disinfected immediately after you get them. A powerful shock, filter, and bleach will help you defeat this enemy.
Your tub water will have yellow tinges if the algae have turned yellow. Yellow algae are painful because they resist most disinfectants, even if properly treated. It likes dark, warm water - so you can find it in a bathtub after you leave it on for a long time.
A thorough water balance followed by a high-level chlorine shock will effectively exterminate these pests.
Regular maintenance ensures you always clean your hot tub and keep the water in perfect condition. That means checking the chlorine levels in your water regularly and adding sanitizers as appropriate.
