Week 4.5 !
I did some changes.
1-Trimmed the Cardamine and moved some of it around.
2-Moved the Ludwigia to the front and the Aponogeton to the back. I think it looks better this way.
3-Changed the bulb from 10,000k to 6,700K. Also, I moved the light fixture from 18" from water surface to 10". It brings in way more light intensity, but because of the plants mass now, after 4 weeks, I think they are doing very well to keep the algae in control. A lot of bubbling from the plants (; .
