How do I remove manganese from my pool?
Superchlorination is the best way to treat manganese staining. The superchlorination oxidizes the manganese completely and allows it to settle to the bottom of the pool. It can then be vacuumed out. The “rust”-like substance that settles on the pool floor should be vacuumed out.
What causes pool discoloration?
Calcium deposits and scaling - This type of pool surface discoloration is caused by high levels of calcium in your pool. Scaling usually happens at the water line where the excess calcium in the water clings to the pool surface and the water gets evaporated by exposure, leaving those less than attractive stains.
Why does my pool water have a blue tint?
Water Turns Light Blue “You notice the blue effect when you have a large volume of water because of the way molecules are slightly absorbing light from the red end of the spectrum,” Coxon says. The deeper the water, the more blue it appears. He also points out that the same thing happens under artificial light.
Do water filters remove manganese?
Precipitated manganese is easily removed by a filter, but it is not removed well by a water softener. It is important to understand that a water softener is an ion exchanger. It deals with un-precipitated ions. Filters can't remove manganese or iron in their un-precipitated state.
What does manganese look like in water?
You may suspect that manganese is in your water if the water is discolored (brownish-red), causes staining of plumbing fixtures (faucets, sinks) or clothing, or has an off-taste or odor. If this is the case, you should have your water tested for manganese by a state-certified laboratory.

Our pool has turned a beautiful shade of purple just in time for Easter. When we shocked it a few days ago it turned green. Pool store checked water and said lots of iron in it (pool is 6 years old and we have never had this problem). Used Bioguard metal remover and 2nd application of Sparkle up today.

I have had this same problem. I have not determined the cause or the solution yet. Have you? Any help would be greatly appreciated.
Guest Bill
I've had the same problem for about a year. At first, the pool vacuum lines were stained purple at the water line and there was purple staining on the tiles at the water line. This season, the purple cast is attaching to parts of the pool plaster, as well as coating the plastic of the pool vacuum housing.

Re: Bright blue to light purple water
I believe that magnesium in the water is generally what causes the purple color, although it's been awhile since anyone here had a problem with it.
Re: Bright blue to light purple water
If minerals are present in the pool water, they can cause the pool water to turn green, brown, yellow, and even purple. The water would look clear but discolored. It can be very difficult to distinguish between green water caused by green algae and green water caused by a mineral problem.

Re: Bright blue to light purple water
I wonder what website THEY got it from. I have seen this same quote almost word for word on about half a dozen sites.
Re: Bright blue to light purple water

How to remove metal stains from pool?
Steps for Clearing Metal Stains in your Pool 1 Get your free chlorine to 0.0 ppm by not adding more chlorine. This might take a few hours or days depending on the level of FC in your water. 2 Add in the Swim's Polyquat 60 Algaecide after getting the chlorine to 0.0 ppm to prevent algae from growing in your pool during the process that might take a few days. Polyquat 60 or 60 Plus is the best algaecide for swimming pools, because it introduces no copper in your water and is also very effective in preventing algae. 3 Get your pH to 7.2 using pH minus. 4 Put your filter on circulation and add 1 pound of ascorbic acid for every 10,000 gallons of water in your pool to get stains away within 24 hours. 5 Get the pH back using pH Plus. Then raise the TA using an alkalinity increaser, since ascorbic acid will reduce both. 6 Add chlorine to raise your FC to around 3 to 4 ppm.
What does it mean when you have little chlorine in your OCLT?
If little chlorine is used up (0–1 ppm), the OCLT result indicates it is not algae or any organism that could have used up a lot of chlorine (above 1 ppm). Thus, it's can only be metal staining as a result of oxidization by chlorine.
