eaglefan-its my understanding that monit caps will be ok under vhos or pcs. they dont get the same growth as metal halides (side note, bummer about TO, but the eagles still have a good chance)
ricky, if you are serious about doing montis or any sps then look into metal halide lights. i personally like having metal halide bulbs (between 10,000k to 14, 000k) as my "white lights" and vhos as actinics. with your tank only being 15 in deep then either 150 or 250 wt HQIs or 175 or 250 wt mogul sockets would be awesome, with 2 36 in vho bulbs. hth, but look in the equip forum or do some searches. lots of folks as about lighting and there are many opinons about it. again, if you want sps corals and clams, get the MH bulbs.
shawnts- dude dont worry, your frag will grow out before you know it, especially with high kalk/alk and mh. good luck with them
again thanks for the comments!
