Pics of growth
at 6 or 7 day
First pics looks like not enough light. Second looks like too much.
If there is any yellow, it's too much light.
First pic for amount and second for color.
So yes - color yellow. Second pic describes it rather precise.
What is minimum hours for ATS per day, before I start reducing wats ? Or let I ask differently. Is there ideal light period for algae ? I am afraid algae will not have enough time to grow if I reduce hours too much ?
That is not yellow.
I'd say not enough light then.
