Hi. I was told by two fish stores (one expert store and one big box) that
you need to buy a filter that is sized for twice the size of your tank.
So
if you have a 55 gal tank, you need a filter that is sized for a 110 gal
tank. In other words, ignore the recommendations on the box. This didn't
sound right, but two different places recommended the same thing.

Any comments?

thanks,

Hello,

my filter is dimensioned that about one tank content pass it in one hour. I
heard this is good for the bacteria culture which lives in it.

greetings
