Sorry for being so inactive lately. The tank has been seriously neglected and has only seen a 75l water change in the last 5 months or so. Corals have lost a lot of color but most seem to be growing at a rapid rate. Here's a few pics I snapped today.
Tank still terrible neglected but growing. 1x 60-80l water change in 6 months. Planning on redoing the entire scape soon. Pic from this evening. If you look at the coral on top right hand side, there are now 4 branches hitting the water surface in less than a month
