Interpet Two Month Service Pack for Nano LED Aquariums,12 x 19 inch

This size is not very common so I was pleased to find them, not as good quality as they were a few years ago the top filter material could be more dense, they fit well

Says to change every month but filter needs changed sooner.

it's ok, however, as someone said, i find that I need to change it every week rather than once a month as it recommends.... too expensive for changing it so often..i have decided to add another filter to my 19l tank and see if this can keep it better

Does exactly what it’s meant to. Great!

Shame it has to be replaced every month. Quite expensive hobby it is.

Does what it says. Best price I could find was on amazon

Clean water and very happy fish!! 😆

Bargain price and good quality filter, will be back for more.
