billfish Posted February 27, 2014 Report Share Posted February 27, 2014 Is there a mathematical way to work out what is the minimum size sump required for tanks? I'm not doing one but was asked this question today . Litres , media area all that sort of stuff:frusty: Link to comment Share on other sites More sharing options...
M&J Fabulously Fish Posted February 27, 2014 Report Share Posted February 27, 2014 I think the absolute minimum you want is 10% of the total tank volume. Bigger the better I think. On my blue dolphin tanks I have 3 4x2x2 tanks and a 4x2x2 sump running them But that's just my opinion. Link to comment Share on other sites More sharing options...

The only sumps I have had was a 300litre that sat under a metre cube and a couple of 3 footers that were attached to racks with 2foot cubes Link to comment Share on other sites More sharing options...
