Hi everybody, need some advise here, hope you could advise me. I have a 3ft tank of the following configuration;

atman cf1200 cannister filter(ceramic rings;substrate pro;biohome)
2 roka boy filter (additional mechanical filter)
1 uv light
contents: orandas, ryukins & black moor

The water in the tank is crystal clear; but cannot understand why is there a tinge of green color in the water; tank is not under direct sunlight unsure.gif

PH is around 7 - 8. Can anyone please advise? Thank you.

hi goofy, sorry, i am not too sure how u could managed to get a green tint in your water. Initially thought your UV could be a blue light, but now a different story. Probably a photo of your tank would help us understand.

Do provide as much information as possible.
