... water as it will effect the balance (well a rusting tank will!) I suggest doing a lot of calculating as to how many fish you hope to put in it and then designing the rest of the system on paper before committing. Maybe you've already done a drawing? If so put it here and I'm sure we'll all try ...

Well maybe if we add solids filter on that bypass then we make use of the energy expended. :thumbleft: I have a question, how would a ball valve differ from head height? or are they the same?

Hi Perklis, I just read your post and agree with 1 2 and 3 and then got a little confused on 4. Did I misunderstand or are you saying you will start with 572 fish at 450g each. If that is correct then 572 fish in 4294 litres is only 7.5 litres per fish ...
