Looks like the new lights have been working well for your tank. It looks great. Just one idea for the foreground and that is just using some moss. Take your choice of what kind, but the dark green moss with the japanica may look good. The mesh you would use to hold it down could be cut to fit in perfectly. That is all I got for now on that.
It looks like you have the adjustable legs on your Coralife and a glass top. Did you have some glass cut to fit or I am just seeing things? Also, how has your fert program changed with the increase in light.
