The other day I managed to obtain three 50 gallon cold water tanks. I'm pretty sure that I want to use three of them for growbeds and two as fish tanks.
1). Should I connect them together for convenience in pumping?
2). Should I have different species in each tank?
OR use one as a breeding tank?
50 Litres will only support 8 or 10 fish and that's not really enough for me.
Is 'pea gravel' ok or is it too small for the growbeds? it's typically 6mm diameter.
No doubt I will have more questions as the building and cycling proceeds.
Any guidance much appreciated at this stage.
PS I live in Devon UK, so I think trout is the easiest fish to start with for our cold winters.
