Hey guys kind of a new to the hobby but definitely committed...small pockets but a big heart...I'm looking to buy a rather large tank to house my silver aro.i was thinking 265-300g. I was wondering if someone could let me know what are some good filters. I read up on a couple online I was hoping someone with experience could recommend a brand/model. Canister,hang over, sponge, etc? Also how does a sump work?
