Is saltwater algae alive? Also, is saltwater algae that disgusting green stuff you see in swamps?
Hi, and welcome to the site!
Algae is like what I call marine plant life, but it really isn't. It is alive, and it grows if it has the right food. That means the water in your tank is not pristine. Regular water changes, don't overfeed, have good water flow from your power heads, and never using tap water for your SW mix is the only way to prevent the nasty stuff from growing.
Some algae such as hair algae is ugly and very much looks like the swamp stuff...it is called hair algae because it grows in thin ugly hair looking streams. Then there is microalgae, it's kind of a film on rocks, snails will eat that stuff and keep the tank clean for you..
The ugly hair algae is a macroalgae. It's a
very invasive ugly type. However there are also some very beautiful algae...reds and browns (gold) and some very pretty greens. Check out "Golf Coast ecosystems" macoalgae if you have the right type for your system, is very good for your tank water. It feeds on Phosphates, nitrates, and ammonia...Then as it feeds on, and grows from those bad nasty tank parameters, you remove it from your tank when you remove the overgrowth....We call it harvesting.
If you have the pretty macroalgae, it will also out compete hair algae for food, and prevent the nasty stuff from getting a foothold,
