Aquarium Water Abnormally Green

[TheRedDiscus]

Hello Everyone! I'm back from my 1 month vacation to Germany! Such a wonderful place! But when I came back, (The tank was cared for and water changed regularly, water is tested regularly, Ammonia 0, Nitrate 0, Nitrite 0, Ph 6, Chlorine 0, chlorimanes 0, water hardness=soft, the typical from a well cared for tank.) the water was abnormally green! Usually you would excpect a minor green in aquarium water, but [bThis![/]b] is abnormal!





Comparison

Please Help me!!
