k i would bring up the salinity to 1.024-1.026 (i like 1.026) and u need the PH to be around 8.3 but then again ur new with the LR well i never had a problem keeping it there. also u want to pick a day of the week to do a 20 percent water change. i like sunday so i do it every sunday every single week even when i was cycling=P
so far so good trust me once u keep the water at those levels u'll see it growing with ur own eyes, like with me it started from a few specs to circles now as big as a dime and some even started to grow on the glass=P
