Amazing.
I like how towards the end their you changed up your plant choices to have less broad-leafed plants such as swords and replaced them with a fine-leafed plant like rotala. It probably made better use of the Co2 system, and made it easier to balance nutrient levels?
What was the second electrical device you added in the background on the Feb07 picture. More Co2 or something?
Lets get some specs! I am guessing those are 2 HOT Magnums, with a nice digital Co2 system running. Maybe a canister or two underneath. The lighting is probably like 2x 250w halides or something crazy with 6500k pc's as supplemental.. edit: Theres actually TWO FIXTURES on that tank, no wonder. Like 8x96w pc 6500k's..?
