So, i've relented on my 'i can get away with a small internal filter' thoughts... my water was perpetually full of bits... which i didn't like.
Anyway, The tank now has a tetratec 1200 and a 900lph hydor koralia nano pump....
What's the best arrangement of my outputs...? The koralia is great, but i have valis along the back of the tank now and it keeps getting wrapped around the pump if i put it in each of the rear corners... I've currently got the tetra inlet a one end and the oulet at the other end using one section of the spraybar with drilled out holes facing the glass. I did this to ensure that the water has to flow right across the length of the tank to the filter....
What to do with the nano though?!
