What is the black stuff coming out of my Jacuzzi jets? If you own an excellent hot tub, you should know that the hot tub is going to last you for several years to come without costing a lot in terms of maintenance.

You must follow a simple maintenance routine to ensure that your hot tub remains in prime condition. Consistent maintenance doesn’t require a lot of effort or energy.

Mainly it requires a few simple tasks such as cleaning the filters, draining and refilling the water after a few months, and then making sure that you follow the maintenance schedule as required by the water system.

As long as you keep the hot tub neat and clean and make sure you carry out regular maintenance, you won’t have to worry about mold, mildew, or algae growing in the hot tub. But, these things can occur from time to time.

If you notice even the smallest hint of mildew, mold, or algae growth in your hot tub, it is important that you take action right away. In some cases, you might not even see the visible signs of mold or mildew, but a musty smell may hang over the hot tub.

If you can smell this odor, it’s important that you take action as quickly as possible and then take appropriate steps to prevent the mildew from coming back.

One of the first things that you should know about mold, mildew, and algae is that they all have a very different structure organically. An algae is a plant, whereas the two others are part of the fungal kingdom.

Needless to say, you wouldn’t want either in your hot tub. The combination of chemicals in your hot tub can cause the algae to take on many different appearances.

It may look its natural green, or it may look yellow, black, or even white. With time, the texture of the water is going to change as well. It may look cloudy or greenish over time, and you will notice a slimy feel every time you touch the shell of the hot tub.

Algae usually appears in hot tubs when the pH levels are not properly balanced. If you do not use appropriate amounts of sanitizers in the water, such as chlorine or bromine, it could eventually cause algae to grow.

If your hot tub is kept under the open sky, it’s going to promote the growth of algae. Needless to say, it would not be a wise idea to leave your hot tub uncovered for longer time periods, as that’s just going to increase the growth of algae.

On the other hand, the appearance of mold and mildew can cause other problems. You might notice something white floating on the top surface of the water in your hot tub.

You might even notice patches of discoloration appearing on the shell of your hot tub. Mildew is generally apparent on the surface, so it doesn’t take a lot of effort to wipe it away on your own.

However, mold generally appears on spas that are not properly maintained. Neglect is a major issue. Mold can be caused due to lotions, cleaners, soaps, and a bunch of other things that are usually transmitted through a person’s skin.

With time, the mildew is going to get stuck in the jets, the filters, and the pipes. Keep in mind that the mildew and mold won’t appear directly in the water, it will first appear on the cover before moving toward the water.

What Is the Black Stuff Coming Out of My Jacuzzi Jets?

The black stuff coming out of your Jacuzzi jets is likely a mixture of mold and mildew. Apart from that, other things such as oils and bacteria are likely to cause problems and may eventually turn black.

Even moisturizer can wash off your skin when you get into a hot tub, and will eventually accumulate in the pipes. You have to understand that these substances usually leave a residual effect, and this is what eventually comes out of the jets.

It can be obviously infinitely disgusting to see some black substance oozing out of the hot tub, so you need to take appropriate action right away.

How Do I Get Rid of Black Mold in My Jacuzzi Tub?

If you can see black mold coming out of your Jacuzzi, it’s a clear sign that your hot tub has not been cleaned properly. You need to follow a series of steps to clean the Jacuzzi.

Thankfully, you should know that it doesn’t require a great deal of effort to clean the hot tub all on your own. Here are a few steps that you should follow when cleaning your hot tub.

Fill it up

The first step is to fill up the hot tub with water. You will need to make sure that the hot tub is full; there should be a minimum of two inches between the water level and the jets, so you need to make sure that you continue filling it up.

The hot water is going to assist in getting rid of the gunk. Once you have filled up the hot tub, add around two liters of distilled white vinegar in the mix. Vinegar is one of the most effective substances that you can use to clean up the gunk naturally.


Next, you just have to activate the jets and let them run for around 20 minutes. You will want to make sure that you close the site valve if there is one. This is going to ensure that the water continues to run through the pipes instead of escaping.

The vinegar is going to continue cleaning the gunk from within the pipes, and the jets will be cleaned out as well. Once you are done with the jets, you will then have to wait for around 20 minutes for the water to become still.

Once you are done, you need to get all of the vinegar-laden water from the hot tub. You just have to drain it out of the Jacuzzi, and then fill it up with cold water.

Let it pass for around 10 to 15 minutes, thus allowing all of the vinegar to escape from the plumbing of the tub as well. Now that there’s no vinegar in the hot tub, you need to clean it up.

Drain out all the water and use a soft microfiber cloth to wipe it clean. Once you are done, you will notice that there will no longer be any slimy texture on the shell, nor will you have to worry about black flakes from the jets.

Ideally, it’s best if you clean the hot tub after regular intervals; usually once a month. Hot tubs are an excellent investment and provide a lot of benefits, but you have to understand that these things require maintenance.

If you want the hot tub to run smoothly and avoid such issues, you need to make sure that you keep the tub neat and clean. If you want, you can also use bio cleaners to keep the hot tub sparkly clean.
