Greetings! I've been keeping freshwater planted tanks for a couple years now, and after much hesitation, decided to try put saltwater! I currently only have a 2 month old 20 gallon, where I plan on keeping macroalgae, some softies, and a couple small fish and inverts. I'm hoping I can apply some of my skills growing freshwater plants to macroalgae, as it's what got me interested in saltwater from the start.
