What external filter would you recommend for a tank that holds about 180 litres? I have always used the X04 range from fluval but noticed that after a year or two they get quite noisy. Does anyone have a Rio 180 or similar that could recommend an external to me? I tend to agree with George, that filters needs high levels of turnover. So I tend to go for about 5-7x the tank volume per hour.
