No, it's Suzy from SWPlantedTank.com!
There actually are some vascular plants, with root systems and stems and the like. My only plants are mangrove trees. Some people have tanks with only plants, but we like to call them seagrasses. They can make a stunning display, but I do not think they give us the vivid colors that algae can.
I do not add CO2 or fertilizer persay, but I do overfeed my seahorses and add iron.
A few of these specimens are from the genus Caulerpa. They are actually the most finicky. The other genus are much easier to care for but they do not grow nearly as fast.
Do some people here have sw planted tanks?
