Are you seeing a white substance forming on the surfaces of your hot tub and maybe even in the water itself? If so, there’s a good chance that you have white water mold growing in your hot tub.
Don’t worry, it’s a common problem, but one you need to solve as quickly as possible. First, let’s talk about what white mold in your hot tub and what causes it. Then, we will move on to treatment and prevention.
It always helps to understand what you are dealing with, so first I want to discuss what it is and how it ended up in your hot tub. White water mold in a hot tub is not algae, although some may tell you otherwise. It’s actually a naturally occurring fungus. While it causes some of the same problems in your tub, water mold is more animal than vegetable.
Because it’s naturally occurring, it is a problem that all hot tub owners must be aware of. If let your hot tub go without thorough cleanings and regular water checks, this mold could begin to grow and flourish in your hot tub. Once you get it, it can be tough to get rid of it. However, if you do things right, you should be able to get rid of it once and for all.
If you find yourself with a white water mold problem, you will have a little work ahead of you. Whatever you do, don’t wait. The longer you let the mold grow the harder it will be to get rid of it for good.
Once you have finished this process, regularly test your water and watch for any more growth of this fungus. If you see any at all, repeat the process above.

As I said, once you get white water mold, it is a pain to get rid of. If you took the time to read the steps to get rid of it you know what I mean. The key to white water mold is prevention. If you properly maintain your hot tub and regularly test the water, then you shouldn’t have any problem. Here’s what you need to do:
A chlorine-based hot tub shock helps treat cloudy water, kill bacteria and algae, and remove contaminants after heavy hot tub usage. This formula also contains an oxidizer, which will help break apart any combined chlorine or bromine that's been used up in the water.
If you make these maintenance tasks regular parts of your days and weeks, you probably won’t ever have to worry about white water mold again. White water mold doesn’t fair to well against a hot tub that is properly maintained. So remember, prevention is the key to stopping white water mold in its tracks.
Let’s be honest, white water mold is gross, and no one wants to have to deal with it in their hot tubs. Still, it is a common problem and one that is growing as more and more people bring hot tubs home to enjoy. If you are a new hot tub owner, I cannot stress enough how important proper maintenance is to a healthy hot tub.
If you don’t maintain your water, white water mold and other contaminants can flourish in your hot tub. Over time, this can lead to a nasty contamination that is hard to get rid of without a lot of hard work on your part. However, if you properly maintain your hot tub, you shouldn’t have anything to worry about.
If you do end up with white water mold, don’t worry. You will be able to get rid of it, but it will take work. Once you do clean out your hot tub, remember to keep the water properly maintained and clean so you won’t have to worry about it ever again.
