I spent 2 days to find out the cause of why my tank (water) is tainted green. alot of you guys suggested that it would be algae but it's a new tank (with old sand). anyways if you look at the tank (with the water inside), the water looks green but if I just look straight the water (no glass), it's all clear and good. Now i'm 75% sure it's chlorine cuz it smells of it (there's chlorine in my tapwater) and I read that chlorine chemical are green (not so sure because it was just one sentence with no explenation). Also pool water is blue right??? My tank setup is a day old and I changed 30% of the water today. It's not blury anymore, just a slight but extingustable green colour.
thanks
