hey whats up i have a40 gallon flat back hex tank and it is acylic tank this tank is used for fresh water fish. for about 2 weeks now i have noticed that my water is looking greenish and its not going away i did a 25% water change and did't go anyting. i have just a flu light above it so i have no clue what it could be.
 
Is the tank near a window? Excess sunlight can cause this.
 
i have the same problem before, it doesn't matter how much water it change, the green water will come back.
i went and purchase a stuff call fincare 1 or 3 (not very sure), it remove the algae in the water, 2 days later is all clear.
hope it work for you.
