We all find ourselves looking at an aquascape and wondering "How on the earth do he/she do it?" We're talking about perfectly healthy plants trimmed to perfection, fish swimming in tight formations, eye popping photography, and most importantly for many aquacapers, the tank appears to be algae-free. Well, we all know nutrient balance within the system is a key component to a healthy tank. However, sometimes there are some hidden secrets that advanced hobbyists are not sharing with the rest of us. For example, maybe some of the great Iwagumi HC layouts are initially grown emersed, and simply filled filled up with water for the photo shoot. None would be the wiser. Do you think we are not being told something that sets the average person apart from these "gurus"? :ehhh: -John N.
