The filter in my little shrimp tank died a while ago. I've just kinda left it, doing weekly water changes and thinking 'well it's only shrimp, they're not much bioload anyway.' Now I'd like to be a bit kinder to my shrimp and I am considering putting 3 scarlet badis in the tank for a bit of fishy movement.
The tank is a 19l (I think) triangle. Previously the tank had a Rena Superclean 40 which did the job but the flow was a bit on the high side and buffetted the shrimp about. It also took up some space in an already tiny tank. To make life even more interesting the tank is in a bedroom and thus needs to be as quiet as possible. I have considered a HOB but the tank has a raised plastic part over the top of the tank glass and I can't find any of these of a suitable size, they're all too long!
Does anyone have any advice about the filter possibilities? I'm not averse to a bit of DIY when it comes to either the filter or the tank.
Cheers for your help!
