I have coralife ballasts they are 150's should i replace them without there being a need to.Also, is there anyone out there that would say its better to go and get new reflectors and bulbs to greatly incrase the PAR values. Over getting a new light unit. I have a 120 48x24x24 and im trying to do a budget being that i have the misses to try to explain the costs to :givebeer:...so in everyones mind stay with the 150's and get new reflectors and better bulbs or just go with 2-250 watters and call it a day. The guy that is selling the unit is hooking it up as far as price goes im just lost and wanting ask questions first. Im getting decent growth now i have a huge colony of TRI-Color acro but i bought it like that its growing but my other frags are slowly taking off,is this an affect of unsing lower watt lighting ? or using sub par equipment? I kno that i can almost get the same par values if i used the best of the best for a reflector and bulb .And is there a optimum level of PAR that must be achived before the corals grow like weeds?
