Spa and hot tub color problems can appear out of nowhere and they can be very problematic most of the time. The thing you have to keep in mind is that the color can change to yellow, green and other colors. So you have to figure out what causes the color change. And once you know that you can handle the issue a lot easier and eventually solve it in a proper manner. Yes it’s going to be a bit tricky to achieve that, but it all comes down to knowing the cause first.
Pink water
Most of the time pink water is caused by pink algae. This is not a common color, but when it does appear it shows that there are some mature pink algae colonies. The problem is that this is not easy to remove. You have to hit it hard with shock and you can also use a purge product in order to clean crevices and lines. Replacing the spa filter and bleaching all spa items is crucial if you want to avoid any problems here.
White water
It might seem fine, but white water is a problem. Things like air in the system that causes micro-bubbles, bad pumping and filtering, even high alkalinity or calcium can be a problem and you really want to figure out how that happens. You can also have white mold, and that’s the usual suspect here. Raise the chlorine levels to 30 PPM and while there try to run the spa for several hours with that solution inside before you drain it. Rinse all the removable items and replace the filter. You can even use a biofilm remover to clean pipes.
Brown water
This appears from contaminated water or it can have high levels of iron oxide. Even if the filter cartridge should remove some of it, this will not do a great job every time, so try to keep it in mind if possible. Ideally you want to use a pre-filter on the hose, it should work.
Yellow water
This one appears because there’s a lot of pollen in the springtime and that can enter your water. There can also be iron oxide in your water. Again, it’s a good idea to use a pre-filter if possible as this will remove minerals. And in case the bromine levels are way too high, you can use a shock treatment and then scrub and bleach wash your spa.
Green water
An excess of copper can lead to green water. And on top of that, you can also have algae growing in your spa water, especially if you don’t have a good protector above your spa. You need to use products like the CuLator packets or Metal Gon.
Using these treatments is a very good idea if you want to keep the spa water safe. Yes, sometimes colors can shift really fast and you have to figure out what method you can use to solve this. It’s not going to be easy, but if you do it right results will be great and that’s all you need in the end!
