New to the hobby…. Making the switch from freshwater planted tanks. I am considering buying a 200 gallon tank because I know me and I don’t want to outgrow this tank in one year and have to start over. My question is…. I learned the hard way that more is better when it comes to a planted tank...

Hey y'all, I've had my reef for a few months now, and this substance has started growing on the rocks and glass.
