well if any of you guys remember a while back i was gonna buy a mh set up for the good ol 29 gallon well, i i changed my mind and bought a 4 x 65 watt power compact retro fit which = 260 watts of pc lighting

now my actuall question is with 260 watts of lighting will i finally get my xenia to start growing like weeds, the thing is prior to the new lights i had 110 watts of pc lighting and the growth was horrible for everything exept the encrusting gorgonian which ive had to frag and flush many a time and my pom pom xena which spread but very very very slowly
pluss when i had the 110 on a 20 gallon before i went with the 29 i had awsome coraline growth, well since i upgraded the tank the only spot that seems to grow coraline is indide the overflow, hopefully the new lights might have it spread onto my rock work because looking at green and brown rocks
makes the tank look pretty boring imo

i might gut the the 110 watt system and figure out a way to wire that into the canopy granted i can make room for it

also how often should i change the pc bulbs, i been doing it every 8 months give or take a month
