    I did a water change and found that the water is blue tinted instead of greenish or clear. Any idea why that is?

    How much of the water did you change? Was it greenish/clear before and then blue after?

    I did a 50% water change. Yes, it was greenish before and now it's blueish

    Is it strongly tinted? Is it possible that the appearance is just a change in the intensity of the before colour?

    I wouldn't say it's strong, but its noticeable. I suppose it's possible.

    Water is actually blue,you can tell if you look at the ocean,people might say that its just a reflection of the sky,but thats not all there is to it.

    Water actually has a very slight blue tint to it.When seen in a small volume it seems colourless to humans,but when seen in a large volume,for example;the ocean,it will be blue.Its because in larger volumes the blue tint will be denser and it will be appear blue.When you go under the ocean,it appears blue right?
