lighting a 90g advice wanted :)
will duel 175w mh with actinics be enough for a 90g for sps corals (acros etc)?
if its not should i just go with coral lifes pc 260w and keep lps instead i would like to keep a mix of both but from what ive seen a read sps for the most part need min of 250w mh with actincs,any thoughts or ideas would be helpfull thanks john..
