My temp usually hangs around the 77-80 degree range. My alk and calcium I try to keep at 450ppm and 8-10dkh. My salinity is usually around 1.0235 and all my other parameters read 0 (nitrates, amm, phosphates, etc.) My pH is 8.3. Lighting is 2-250 MH SE 20K bulbs. I run a skimmer for 4hrs everyday. I feed my corals reef roids and rotifeast (alternate). I dose B-ionic daily and Lugols once a week. I do water changes at least once a week (~10%). I hope this helps.
