Having your hot tub water turn green can be a bit of a shock, particularly if you haven’t checked on your hot tub in a while.
However, if this does happen to you it’s important to recognize why it’s happening and what you can do about it.
This way you can fix the problem and prevent it from happening again.
So if you would like to learn why hot tub water turns green and how you can avoid it, then read on.
Why Hot Tub Water Turns Green
When people report that hot tubs have turned green typically they may describe it as cloudy or foamy.
There are a number of reasons why your hot tub water may turn green and it’s important to pinpoint exactly why it has happened.
One of the most common reasons for hot tubs turning green is because of algae build-up. Algae can build up in your hot tub if it hasn’t been cleaned properly for a while.
Usually when algae begin to accumulate it’s a sign that the sanitation level in your hot tub isn’t high enough.
This means that within your hot tub you may not be using chlorine and bromine, if you are using it then you may want to consider altering your dosage.
Another reason for your hot tub water turning green is when the minerals in your water aren’t right.
For example, if the iron, manganese, and copper aren’t right it can cause your water to turn green.
How To Get Rid Of Green Water In Your Hot Tub
Getting rid of your hot tub’s green water isn’t as difficult as you might think. However, there are some things that you should be aware of.
One of these things is that the earlier you can get rid of the green water, the better.
If your hot tub has had green water for a while then this can make it harder to get rid of it, although there are still some methods that you can use.
1. Drain The Green Water
To start, you should drain the water out of your hot tub, oftentimes once the water turns green itself difficult to see what is actually in it.
This is because the water can turn cloudy making it more difficult to see into it so if there is anything clogging up the pipes or excess residue it may not be visible.
Also, the green water needs to be drained so you can start cleaning the rest of the hot tub.
2. Start Cleaning
Once your water is drained, now it’s time to start cleaning the hot tub the whole way through.
You should start by getting rid of any large amounts of excess residue, if there are any algae then you should remove it from the drains.
Also, if there are any build-in pipes or thick residue then it needs to be removed, a pair of cleaning gloves and a sponge can help with this.
After you have got rid of any of the bigger bits of residue, you want to do a more thorough clean.
To do this you can take a clean cloth and use some hot tub cleaning solution.
It’s really important that you cover every single part of the hot tub with a cloth to remove any bacteria which may still exist.
3. Refill Your Hot Tub
Now that you have cleaned your hot tub thoroughly, you can start refilling it again.
We would recommend that you leave 12-24 hours after thoroughly cleaning your hot tub before you fill it up again.
This is because the cleaning solutions can take some time to settle before the hot tub is ready to use again.
Other Cleaning Solutions
There are some instances when your water may have turned green quite suddenly, if you notice that this does happen then it may be reversible without needing to drain the water.
In this case, you should remove your hot tub pillows and add roughly 60g of bromine or chlorine per 1500ml of water.
Then you should remove the hot tub cover and put the jets on a cycle. Once you see the water has gone clear, leave it for 12-24 hours then you can enjoy relaxing in your hot tub again.
When using hot tub cleaning solutions, it’s always important to use a solution that is from a reputable supplier and that you follow the instructions.
How To Prevent Your Hot Tub Water From Turning Green
The process of preventing your hot tub water from turning green is quite simple, you need to clean it regularly.
While most hot tub owners do have cleaning products and a general schedule, it’s sometimes hard to stick to it.
So to keep your hot tub cleaner, make sure you set out a day and time that suits you roughly once a week.
If you are using your hot tub regularly then you will also need to shock your hot tub once weekly too.
And every month it’s a good idea to drain your hot tub so that it doesn’t get an excess build-up of algae.
