This is my new 75gal. tank. It will be SPS only. I put 75lbs of LR (45lbs fiji, 30lbs lalo) in 10 days ago. I have been running the lights on there regular schedule. I was wodnering (after reading) should I let the rock sit in the dark for some time? All parameters in tank are not testable with salifert equipment. any recomendations would be helpful as this will be my first BB tank. I have a 20 gal sump also BB(used to be a fuge) that I will make a frag tank.
