Ok so, i know im pretty new to the hobby, but i recently got money for an old project back home and was almost immediatly offered a 55 gallon tank, stand and refug for a ludicrous price from a good friend of mine. Question being the lighting alone. I have a 175w MH over my 30 gallon now but would that be enough to light the 55? and i really wish that i had picked up that second metal halide when it was offered. Furthermore anyone that has a 55 gallon, how hard is it to keep up? ive never worked with a fuge before, and how hard are water changes? thanks for any input you have and if anyone is selling enough MH to lignt up a 55 gallon i will steal it from you. thanks!
