Can anybody pls tell me,why am i struggling to grow a xenia,gsp colony?I am running 2x150w mh's(14k),4x54w T5(2xatinic). I have medium waterflow,waterprams look good,i'm also having phosgaurd and purigen. The current corals are doing well,these are zoa's,2xbubble tips,some brown unknown softies(kinda looks like xenia,but collected it from kzn). Any idea why i'm struggling,coz ultimately i want my rear pane covered with gsp.:blush::yeahdude::whistling::whistling:
