Is your hot tub water green?

If your hot tub water is green and you’ve tried the usual to try and get rid of the green water, we’re here to help. We’re here to share some helpful advice on how to keep your hot tub clean. So, with that said, let’s look at the causes of green hot tub water and how you can avoid this from happening.

What’s causing my hot tub water to be green?

Green hot tub water is commonly caused by a simple, non-flowering aquatic plant. Ok, that’s just a nicer way of saying that it’s highly probable that you have algae in your water after all, algae love to grow under the cover of your hot tub in the dark yet warm water environment.

One of the simplest methods to test if it is algae causing this problem is to touch the inside of your hot tub walls, if it feels slightly slimy to the touch, then the chances are its algae. The likelihood is that this has happened due to either insufficient sanitiser levels (Chlorine or Bromine) in your hot tub or your filter is not performing at its best.

Minerals such as copper, iron and manganese can also make the water turn green. These minerals could be from corrosion of equipment, from copper pipes or just minerals from your household water.

Is green hot tub water safe?

If you’ve opened your hot tub cover to discover green spa water or a green tint to the water, it’s not advisable to use it. However, this can be easily fixed and isn’t a huge issue. If the hot tub water has been green for over 24 hours you will need to conduct a deep and thorough clean.

You should firstly have a deep clean of your hot tub. This includes draining the hot tub and giving it a thorough clean.

You will need to use your garden hose to clear away the green tinge to the hot tub and remove any algae growth. Once the hot tub has been treated for the algae growth and green water, you will then be able to refill the hot tub with the appropriate treatment.

How to solve it.

Test the pH and alkalinity of your hot tub water and try a Hot Tub Shock / Non-Chlorine Oxy Shock. After filtering out the dead algae we would recommend that you look to clean your filter to remove any loitering algae.

If the above has not rectified the problem and 24 hours later, your water is far from crystal clear, then it’s time to drain your water, thoroughly wipe all of the internal surfaces of your hot tub (to remove any remaining algae), replace your filter and refill with fresh water, not forgetting to balance your waters Total Alkalinity, then pH which will ensure you are giving your sanitiser the best water environment to work at its best.

Other considerations.

There are other causes of green water such as the presence of minerals (copper, manganese, and iron is the main culprits) from the pipes that fill your hot tub, or even present in your household water and don’t forget the no-go rules around fake tan. The chemicals in your hot tub will react with the fake tan and result in some interesting shades of brown and green on the sides of your hot tub and in the water!
