Black in Pool Water – Whats it From and How Can I Get Rid of It?
Water colour dis-figurations are a common problem and headache for pool owners. Sometimes, we see that there’s black in pool water, but have a difficult time tracking down information on what causes it and how we can clear it up. This is because it’s not as common of a problem as say, green or cloudy water. However, that doesn’t mean it’s not as bad. We’d all like crystal clear water, so when it’s colour looks a little off we have to worry about staining and so on. Black in pool water is generally caused by a high level of manganese. Most pool colour dis-figurations are actually the result of oxidized metals in the water. These colour changes generally appear when the pool is initially filled or after a shock treatment. This is because if the pool contains metals all ready a shock treatment will oxidize them which makes them easier to see.
