Help with a sump

[Saaqib_Ansari]

Hi I have a 300 L tank currently with no sump. I run a external filter (crystal profi e902). I really want to get a sump but I don’t know what size I should get? Any suggestions?

I would get the bigest one you can do.
In the end the more water volume the better.
I have a 140g DT with a 150g sump.
Calculating everything a run a total volume of 240G.
