Yellow Stains In Pool

Yellow stains in pool.

I have a yellow stain as well and i know what caused it. Our products are specifically formulated to identify and treat a variety of pool stains no matter the cause. Pool steps can leave stains and rust on the finish and age can take a toll on the finish. I have read some other posts pertaining to this but still a bit confused on what to do.

The most common blemish however is usually fading caused by sun damage and tears caused by equipment or debris in the pool. So it only ran for 3 or 4 hours which may have helped to cause the problem. I have a bunch of yellow staining on my pool liner. Shades of yellow can be a sign of excessive iron.

I am stuck with two issues. When there is too much of a mineral present in the water it can begin to stain the pool. Iron can be introduced into a pool by well water or pipe corrosion somewhere in the pool system. I used an algaecide and the next day there was a yellow stain on the wall from my return line all the way around to my skimmer.

It looks a lot like it would if you had mustard algae but when you brush it doesn t come off. For more information download a copy of our complete pool care guide. Sometimes it can be fairly easy to get rid of stains but other times those hard to remove spots can take a bit more than a simple scrub. I also forgot to switch the pump from auto to manual.

Unlike algae iron deposits resist scrubbing and take a lot of elbow grease to remove. If a yellow or reddish color occurs it is an indication that the stain is copper.
