Hey guys me again with another question about my 30 gallon tank. I’m think of changing to a theme and pulling the fake rock out. Now I am thinking of doing a kinda beachish theme with a couple pieces of drift wood in the corners with maybe java moss and have fern in the tank (want to attempt plants). So right now I have cheap fake pebbles in there thou I want to empty. What do you guys use for substrate? And how do you clean your substrate?
