406 is out so shops have 405on sale for $ 299.

I am thinking of using it for 200l or 300l water(already deduct for substrate)

Any comments please? A bit worry about if it is too strong for 200l or not enough for 300l?

It has Max flow of 1300l/hr, circulation flow of 850l/hr, and it is rated for 400l max.

I have one on a 254 ltr tank. Nice filter.

how long do you maintain it?

About 2 feet :dunno:

Sorry I mean how often

Possibly only every 3 or 4 months.

Basically when the flow starts to slow down the the filter pads require cleaning.

I have 7 of the fluval x05 filters in total. Never had any issues.

I have several of these, they are great and you won't have any trouble with the flow. You can adjust it to be lower flow if you need to.

What size tank do u ran them on? Would it be ok for a 300l?

In my opinion you cant have to much filtration on a tank, in fact i prefer to over filter my tanks. The only problem you you might have is to much flow. This is easy to solve as mentioned earlier by reducing the flow out of the filter. Personally I say if you cant afford it, get it.

On my 300L tank I have a filter rated for 400L and one ratted for 200L both running on it.

I have a 406 running a 200L tank and a 405 running an 80L tank.

OK thanks very much guys, it is very helpful :-).....so hard to deceide if I want a 350L or 240L new thank >_

If that is supposed to be tank, go 350, as on the whole I find big tanks more fun, easier, and look more impressive.

Awesome filters.
