i just got my 542watt light for my 100gal
everything went good setting up...the fan is quiet, balast is quiet. looks like you can add another fan, i think i am going to do that when it starts getting hotter. anyone else add another 3" fan?
little hard to get the plastic cover off to get at the bulbs. the light looks great, glad i went with MH i love the shimmer and i should be able to keep anything i want with 5.4 wpg and for the price $360 shipped, ordered it on sunday, arrived today.
now i need to get some timers
good to hear about the 150/175 bulbs, not looking forward to paying $70 for a 175 when a 150 is $20
