thanks everyone for the compliments.
ivan - i don't have any problem with the evap. i have a 4 inch fan from radio shack in the hood, avg. temp is 74. the fan is on the same timer as the mh. i'd highly recommend MH on the nano, best decision i ever made.
flatzboy- all the equipment is from my old 55 so no, no corners cut. everything on there is rated for 75 gal. plus. ca/alk/ph is maintained w/ b-ionic. when i tried to replace it with something else, all my corals shriveled. when you got a stable system, don't f with it.
robchuck- keep the glass clean with a stanley paint scraper. new metal blade for every cleaning. the salt makes blades rust easily, so you got to replace them.
swim - i got the cb from a shady shop that was ich infected. i treated w/ kent rx-p and he's never been happier. he doesn't eat on my corals or clam or anything. meanwhile, there's way more than the avg. 5 gals. per inch of fish, so they all have plenty of room. i wouldn't think of putting any more fish in there.
thanks for your praises. any constructive criticisms or suggestions welcome.
