In a few months my 960L Tank will be built and ready. The dimensions are: 200cm x 80cm x 60cm (LxWxH). My first question is if I should run a sump made by me which would be about 150L or so or if I should run a fluval FX5 or two or something similar?? How hard are sumps to make and run? Does anyone have any designs that I can have a look at? And also, how does the water get to the sump from the tank? I hear there are a few different methods, but I don't like the idea of space in my tank being used up by one of those overflow boxes in the corner...
Secondly, what kind of fish are suitable? Arowana, ornate bichir, fire eel, oscar, clown knife, black ghost knife?? Are all of these fish OK together??
Sorry for all the questions :oops:
TIA
