substrate for a beginner's small tank?
I've decided to make the transition to live plants in my 10 gallon betta + ghost shrimp tank. I've been using regular aquarium gravel from the local petsmart, and I don't know what I should do when I get my plants...Right now I only have a java fern and moss ball, so it's not really a problem (because the java fern is tied to rock), but I have anubias, dwarf sag, and java moss coming. What's the simplest solution so I can have healthy, growing/propagating dwarf sag? I've also ordered some root tabs, as my plan was to just add that in the gravel. Would that work? I'd rather not empty my entire tank and completely change my substrate...Would mixing in some laterite work well?
Also, I use flourish comprehensive, but no co2.
