ok. what i see here is a lot of softies and lps
, neither of which are high light. i would use 3 of those lumenbrite pendants and hook them to the wall like you did your halides. i would put them at about the same height and use 250 watt, 20k lamps. that would look awesome. (750 watts)
or, i would go the t-5 route and use a 12 x 39 watt fixture. (468 watts)
nice looking tank!
oh...i would also lose the lids. your evaporation will get worse, but light penetration will get better, along with gas exchange, and overall health of the tank.
