hi all bros,she's a newbie,so with those terms dat goes btw bro,think she getting confused.HAHA!!!Sis why don't u try changing ur light bulb to a lower wattage,cos u r not having many corals.When water evaporates,its parameter fluatuates (water chemistry goes haywire)cos u gotta topup freshwater.IMO i think don't try any coral.Few rocks/fishes also looks nice
