Green Hot Tub Water
Sitting in your hot tub is a great way to relax and unwind, especially with someone you love.
To make sure your spa experience meets your expectations each time you use it will involve some maintenance to make sure it always operates efficiently.
At times you may experience issues with the water turning green that are pretty easy to resolve with just a bit of tender loving care.
There are several reasons why your hot tub water may turn green, and there are simple and effective measures you can take for a quick fix that will have you enjoying your spa in no time.
The following questions and concerns will be covered concerning why green water happens:
– Why does water go green in my hot tub?
– Hot tub water is green and smells
– Hot tub water green after filling up
– Hot tub green foam
– Hot tub water turns green after adding bromine
Why Does Water Go Green in Your Hot Tub?
This can occur because your pool has not been cleaned properly, sanitizer levels are too low, improper ph balance, excessive metal content, bromine was added, or an algae issue.
The probability that your green water is due to algae is very rare unless you’ve recently visited a beach or ocean.
If you discover that algae are indeed your issue, you can tackle it with a spa algaecide clarifier or algae control.
The most common causes of green spa water are excessive metal content due to well water and low sanitation levels.
Oxidation during shocking reacts with copper turning it green.
Spa Shock Oxidizer and Spa Guard products are affordable options.
Hot Tub Water Green after Filling
When you fill your tub with water, the plumbing and garden hose can carry metal from the waterline.
The temperature can also affect the water, causing the metal to become more apparent which may be one reason the hot tub is green after filling.
If this happens, the metal can be removed by testing the pH and calcium hardness to make sure that it will adjust to its normal level.
Once this is done the problem should quickly clear up inside of your spa.
Adding CuLator Spa Pack metal eliminator to the filter and skimmer area will aid in treating your water.
Always try to maintain a proper level of sanitizer for your hot tub by using bromine or chlorine, but as a general rule of thumb, bromine is the main culprit for turning your water green as acid water tends to kill off most of the bacteria present and bromine tends to have less of an acidic effect on the water in your hot tub.
Not shocking the water frequently enough could be another reason for green water as shocking helps the sanitizer work at peak performance.
Low pH levels (that’s the alkaline side of neutral) cause an imbalance in the water and allow bacteria build-up making the water green. Using test strips is the easiest way to monitor your pH levels.
My Hot Tub Water Turns Green After Adding Bromine
This may happen due to a dirty filter cartridge. Also, because bromine is a chemical, that may add a slight hint of green color to your water anyway.
Bromine requires less maintenance than chlorine, and if you are not good at monitoring your water chemistry this is the cleaner you want to choose.
You will have to monitor your levels more if you use chlorine, and bromine is also the more stable and effective choice between the two.
It’s the pHin Smart Water Care Monitor for Pools, Hot Tubs and Spas.
It floats in the water and communicates with your phone, telling you what chemicals are needed as and when, so making life easier for any hot tub owner and taking any doubts away immediately.
Is Bromine Safe to Use?
Bromine is equally as effective to use as chlorine. Both are considered safe and healthy for spa and human use.
It comes in tablet form and works with contaminants in the water to help sanitize.
Again, bromine does not have to be added to your spa as often as chlorine as it evaporates out less vigorously and is better at destroying bacteria and viruses. It’s also slightly less irritating to the skin and has a milder scent than chlorine.
Chlorine, on the other hand, is the main ingredient for shock treatments even when Bromine is the main sanitizer, as the shock (making your water temporarily more acidic) is the best way to kill off any bacteria in your hot tub.
Skin Problems Caused by Using Bromine?
Simply put – the salt compounds used in bromine can dry out your skin.
This may cause folliculitis, which is swelling of the hair follicle, leading to itchiness, skin irritation or rash.
Such skin conditions can be avoided by cleaning your spa and cover regularly.
For a quick and natural alternative for relief of these symptoms, you can apply warm water and white vinegar to a clean washcloth, then apply to the affected area.
Using topical medications prescribed by your doctor such as Silver or antibiotic creams will help to clear these up.
These ailments may be prolonged if left untreated.
Is Green Hot Tub Water Safe To Use?
To avoid many unwanted skin conditions that may occur, it is not recommended that you use your hot tub if the water is green.
Your hot tub will be back to normal in no time once you take the necessary steps in properly caring for and treating the water.
So, is green hot tub water safe?
You may get a natural green tint from bromine that will generally clear up after your jets are on for a while. If you’ve tested your water’s pH and cleaned and prepped your hot tub regularly to manufacturer’s instructions, there shouldn’t be any issues with green water, and you can enjoy your spa safely.
If you’ve got your doubts, try shocking your spa to give it a boost of acid, that way making any bacteria or algae unlikely to return for at least a week.
If these steps are followed and green water does continue, call your manufacturer.
Hot Tub Green Foam/Hot Tub Water is Green and Smells
Green foam can occur because of product build-up such as shampoos or lotions as well as bacteria and residue left behind from the hair and skin.
Foam, itself, will die down naturally over time, but the safest option is to drain your hot tub and start all over again after rinsing it out.
The smell that’s coming from your water is either because the pH level is too high or low, or the chemistry of the water is off – check out our recent Hot Tub Smells Bad post on this condition.
Applying these methods to care for and maintain your spa will give you the best outcome for longevity of use and long-term enjoyment.
