Well you have a second subscriber now! This tank is awesome, I really love your choice of plants and hard-scape. It is clear that a lot of thought went into your layout.
I am also setting up a 1.5g cube myself and was hoping you could fill in a few more details about your tank. You mentioned you ordered LEDs for this tank, do you have them on it yet? What LEDs did you order for a tank this small? I'm also curious about your CO2 setup, any details you can share would be helpful.
Thanks, and again, great tank!
