Hello, I've set up a 58 with 250hqi pendent. Added 45lbs live rock going on 3 months. Lawnmower blenny is only fish and wide assortment of snail,cukes,hermits,conch etc. for clean up. My alkalinity is 4.5 meq/l, Ca.4oo+ppm, no measurable amonia or nitrates via salifert test kits. I'm planning on keeping a BTA,pair of tomatoe clowns,6 green chromis, 6 line wrasse, along with clams and some montipora sps. Anyway, how long should I wait to start adding the clams. I've got a blue maxima that's been in a 30 w/96w CF's for 3 months and just don't want to loose it to impatience. Thanks in advance for advice, Rob.
