Enough Filtration?

[Steffyboy]

I always wonder that mate.
I get that much different advice from different people it gets confusing??!!
I just wish there was one rule for every tank and that people sort of had to abide by it!!
People have their own ideas about stuff and it's hard trying to filter out the right answer.
Think it's about trial and error and then in the end you'll get it right...just hope mine is sooner than later!!

A U3 and a U4 together should technically be enough to filter a Roma 200 but you have to rinse the pads every two weeks or so to stop them getting blocked, and check the impeller often. Long term, you might think about replacing them with an external canister filter for ease of maintenance and better filtration. They also take up less room in the tank so look better and you can fit so much more media in them.
