Hey all I was wondering if my filter arrangement was ok? Ive got a 65l nano aquarium with a filter compartment at the back and at the moment almost 3 weeks into cycling My water is crystal clear and params getting better by the day but was just wondering if you would change anything Only got Carbon at the moment but will ad Phosguard and Purigen once the tank is cycled Bit difficult to get a picture because the tank is close to a wall but this is how it looks ?
