Changing Hot Tub Water
Ask any hot tub owner, and they will tell you that one of the worst things about owning a hot tub is that sooner or later you are going to need to drain the water out of it. This is something which is going to take a long time, and it isn’t going to be too kind to your water bills either. So, obviously, you will want to keep how often you change your hot tub water to the absolute minimum, right? Let’s look at how often you should change your hot tub water.
How often should you change your hot tub water?
Generally speaking, you should be replacing every drop of water in your hot tub at least once every three months. Although, you may need to empty it far more often than this if your hot tub is getting a lot of use. Likewise, if you are barely using your hot tub and it remains covered, with the right balance of chemicals inside, then you may be able to keep the water in it for longer than three months.
Obviously, you do not want to be changing the water in your hot tub more than you actually need to do so. If you do, then you will be looking at massive water and energy bills. In a short while, we are going to provide you with a few tips to make it easier for you to determine when your hot tub water actually needs to be changed.
Why do you need to change your hot tub water?
As brilliant as your hot tub filters and the chemicals you use are, they are not going to be able to remove everything from the water. Sure, they will be able to get rid of bacteria and algae. However, the chemicals are not going to be able to clean flakes of skin and makeup that comes off of your body (or whatever else you are putting on your skin). They are not going to be able to remove fabric that has fallen off your clothing. Dropped some food in the hot tub? That is going to still be kicking around. Throw in some natural body oils, and your hot tub is going to very quickly start to fill up with dirt and grime.
It won’t take long before your hot tub water starts to get filthy. Remember; hot tubs are quite small. All that dirt is not going to be spread throughout a large area like it would be if you were in a swimming pool. It is all going to be in the same place. Turn the hot tub on, and you are going to essentially be stewing in your own filth. It isn’t pleasant at all.
Remember; your filter is going to be able to remove some of the dirt and grime, but there will eventually be a point where there is just so much in the water that it becomes impossible, no matter how good your filter is and no matter how hard it works!
What can you do to keep the water clean?
You will eventually need to empty the hot tub. That is something that you simply can’t avoid. However, you may be able to delay the grime starting to build up in your hot tub by following these tips:
- Make sure that you shower before you get into the hot tub.
- If you are wearing makeup or any sort of lotion on your skin, then clean it off.
- Make sure that you regularly clean the filters on your hot tub
- Ensure that all of the chemicals in the hot tub water are kept in check.
As we said; these tips are not going to reduce how often you need to clean your hot tub, but they will certainly reduce how often you need to do it. If anything, it will at least ensure that the water continues to look clean.
Remember; the more people that are using the hot tub, the more unclean the water will get. If the hot tub is packed to the brim, then there will be very little water per person. This means the body oils don’t really have anywhere to float off to. They will all start to congregate in the same place, and this means that the water can become cloudy rather quickly.
Knowing when to change your water
So, how do you know when you change your water? There are a few things that can tell you when the water needs changing. You should probably use a combination of them to know exactly when the right time to clean the water is.
Use Testing Strips
If you have a hot tub, then you need to get your hands on a good number of TDS testing strips. These strips are designed to test how much dirt and grime is in your water (TDS stands for Total Dissolved Solids!). Basically, this is going to be the ‘ultimate’ way to know whether your hot tub water needs to be changed or not.
With the testing strips, you put them in the water, then read the result. Compare this to the manufacturer of the strip’s guidelines and you can see whether the water needs to be replaced or not. This is a test that is going to take no more than a few minutes. We recommend that you carry this test out at least once every three months, or more if your hot tub is going to be getting a lot of use.
Carry out a visual test
If your water looks cloudy or foamy, then you may need to change the water. Some people will add some extra chemicals into the water to try and remove the cloudiness. However, to be honest, if you haven’t changed your water for a few months already, then this is probably not going to be worth it. It can just be a waste of chemicals. Sooner or later, that water is just going to end up being cloudy again.
Remember; cloudy water doesn’t always mean that your water needs changing. For example; if you have changed the water of your hot tub recently, then you may find that the PH levels of the water are out of sync. You may also find that you are not using enough chemicals in your water. You should carry out the relevant tests to see what could potentially be causing these issues.
Carry out the ‘smell’ test
If your water smells funky, then just completely drain it. There is nothing that you can do chemical wise to improve the smell. If there is a smell coming from the water in your hot tub, then it indicates that you are long overdue for a cleaning. Hopefully, your hot tub is never going to get to this point. If it does, then the smells will start clinging to you, and this is not going to be a pleasant experience by any stretch of the imagination!
Cleaning Your Hot Tub
Once you have determined that you need to change the hot tub water, then completely drain every last drop from the hot tub. Don’t refill it right away, though.
If you want to prevent your hot tub from needing to be emptied any time soon, then it is vital that you clean it properly. This means getting inside the hot tub and using a proper hot tub cleaner to scrub down every last inch of it. Yes. This is something that is going to take a bit of time, but it is going to be nothing in comparison to how often you will need to be emptying your hot tub if you do not do this.
At the same time, it is also important that you clean off the filters in the hot tub. If your hot tub hasn’t been emptied for months, then there will be a lot of dirt and grime in the filters and the housing for the filters. You should look into ways in which you can clean out your filters. At the very minimum, you will need to spray them down, as well as cut them in cleaning solution (not literally cut them, don’t worry!). If you have had your filters for a good while, then you may even want to think about replacing them. Remember; filters do get a lot less effective over time!
So, there you have it. You now know exactly how often you should be cleaning your hot tub. This should be, roughly, every three months. However, if you find that the water is starting to get a bit grimy, then you may want to change the water more often than this. Some people with hot tubs that are getting a lot of use may find that changing the water once a month is good for them. This is normally going to be the case if you are using the hot tub every single day.
