Thanks much. And ya, exactly, can always add on a small hob on there if you find you need it. Been purchasing just a few small frags lately to add a bit more life to it eventually. All seem to be growing at a slow pace, which is fine, I've got time to wait. Will need to add a bit more rockwork soon though just to give some height and some space to transplant corals.Sweeeet! Yeah like I was saying in above comments if stuff got to out of control I can throw a hob filter on to help keep things under control. Love the tank Everything looks happy in it
