The filter (250) works very well, is easy to cut off access to water and its maintenance. You only need to be careful to isolate some of the noise.

I have had Sera Bio Fil 130 + UV” external filter installed for a couple of month by now and it can be easily noticed a difference in water condition and its quality. I would not say there would have been previously any problem with having the water clear enough thanks to the effective hood trickle bio filter and internal filter I have used. However, now with the new “Sera” filtration system the water quality and its transparency have become even better. The same to be said about the extent of water purification now, thanks to Sera Siporax filter media and its ability to host beneficial bacteria the total capacity of breaking down the pollutants has significantly raised. To be able to keep such a quality of water permanently, additionally a regular partial water change is still required and that is what I fortnightly do. I would also like to mention quietness the filtration system is functioning with; my aquarium (130 Lit.) is in the bedroom and the filter in the cabinet below it, so it can only be heard a bit when I open the cabinet’s door and put the ear close to it. So far I have been very satisfied with my choice, besides, there was not any problem with ordering the mechanical replacement media for the filter when I asked for it ordered it from “Sera” just for me and it was sent to me with the rest of my order.

My 250 has been in and working for a few days now and it does exactly what its supposed to, water is clean and clear. Its a bit on the noisy side, but it seams to be quiter now than when it first started, probably less air in the system. But its not that noisy either, its only when the room is quite that I can hear it. But for the price I am not going to complain.
