hi to all as you all know that i have a new aquarium of size 6'2'2' so which would be the best filter for it i have 6 oscars in it so it would be a kind of messy
I would probably go with the fx5 they are reasonably priced easy to set up and can handle a 180g tank pretty easy if budget is tight you might find a used one fairly cheap. Another plus is they are fairly simple to work on I had to take ours apart and clean some fine carbon chunks out of the impeller and it was really easy good luck.
