So Mebbid: are you saying that a regular HOB
filter like Aquaclear 110 or Marineland 350 is good enough for a 90g tank for example? No need for an Eheim 2217 or any other canister filter?. I thought the more filtration the better the water quality and less problems with water parameters. I'm no expert on this but people are allways saying that overkill fintration will keep your tank cristal clear and trouble free. I see people with a 110g tank and a Fluval FX5 rated foe 400+ gallons or an Eheim 2262 (rated x 460g) in a 150g tank.
