Macroalgae
Macroalgae are the plants of a saltwater tank, grown in a refugium or the display to pull nitrate and phosphate out of the water. Chaeto is the workhorse, growing into a ball under a grow light, while caulerpa and others add form but can go sexual and crash if left too long. Each profile lists light, flow and how to harvest.
