i HAVE two 204's and clean them out weekly, fortnightly only when pushed for time. They perform better with regular cleaning and like a car - last longer IMO. The fluvals are great. The newer ones have the valve shut-off so that you can take the hoses off without a flood.
I have two medium tanks and both are fully stocked - this means regular cleaning minimises any potential problems.
If the day ever comes that I can get a six foot tank I will be looking at the Jebo which seems to be an excellent filter at a cost most people can afford.
