Tan,

I have same problem as you initially. I don't get direct sunlight, so the carpet algea don't grow. Then i use strong PL light (2x36W) for 3'x2 tub. The result seem good, i got carpet algea (not sure is bright green as the tub is blue) and also green water every after 3 days of water change. If algea still not good enough, just add the light or increase lighting time.

Hope this help.

My other problem is time constraint. Can't follow u guys way of feeding...Anyway, i am trying hard to achieve as much as i can.

Regards
eu
