I will soon have a long shallow frag intended for SPS - Its a waterbox frag 155 (150x54x41cm). I have a large overhang island scape and I want high flow both above and below the platform. But i want a thin fine sand look and I am concerned about bare spots.
My plan was to have a fake sand bed to achieve the fine grain white sand look but with big flow and no bare patches but I read that it will soon get covered in coraline algae. I love the shallow sand bed look but i dont like the crushed alage look. What is the smallest particle size i can get away with? I have one Al nero 5 and i plan a second when i have filled it up a bit. I understand this will be quite a lot of flow for such a shallow tank.
