Filters

[abesapian]

Just wanted some opinions. I have a 55 gal tank with a AC 300 filter. Where should I position the filter? It is currently as far right as I can put it within the space cut out on the back of my left canopy. Also I bought a AC 300 specificaly because it's good for up to 100 gallons but in the past I've recieved advice to put on another AC 300 or AC 200. How much is to much as far as filters go and how they effect the fish ie. noise and water flow?

Thanks for any replies

It doesn't matter too much. Left, right, its all the same.

On my 55g i've got an AC 500 and an XP3. The AC is the noisiest (a slight rattle) and the current isn't too bad. The way i've placed the Filstars spray bar and the output of the AC makes it so its not super strong.
