For my new 20g aquarium, I'm going to be running a 4-5 year old Rena Filstar XP1 that I've had sitting around since my old 10g aquarium.
What is the recommended media for a planted tank? I have very hard water that I'd like to soften some. Should I have a bag of peat in the filter?
Bio-media?
Mech media?
Peat?
Filter floss?
And should I put a sponge pre-filter on the Filstar? Or is that not a favored approach?
