Really good and value for money. One of the best filters. It is a bit big and you have to have space to store it. Excellent product and highly recommended

The Sera fil 250+UV is a very quiet and effective outer filter, easy to install and maintain. Though, it seems to be somewhat hard to find replacements for the mechanical filter media, i.e. the filter mat and filter sponge ...

Sono molto soddisfatto del prodotto, il filtraggio è efficace e la lampada UV anche. Veramente un ottimo acquisto anche se sulle pareti si forma qualche colonia algale

Bought the SERA Fil 400+UV and am really happy with the results it's giving. I have a 300ltr aquarium and keeps the water crystal clear. Very powerful too. Service and shipping to Malta was EXCELLENT. Will buy again.

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.
