During the first year your tank will see all colours and problems it has to learn to stabilize kinda like a child learning to walk, the ultimate solution is patience every reefer wants to solve problems or ditch the real trick us playing things out. Sandbeds have a knack for solving their own problems and messing with it doesn't help and removing it doesn't get rid of the problem, it's all part of becoming established. Some systems establish rather quick some take forever that's where making patient decisions and informed decisions cones in
Someday I'll be doing a bb tank ive seen some real nice ones
