Medicdude Posted November 15, 2010 Report Share Posted November 15, 2010 As a minimum sump should be at least 1/3 the size of the main tank. Quote Link to comment Share on other sites More sharing options...
hustler Posted November 15, 2010 Report Share Posted November 15, 2010 All depends how many baffles, What you plan to put into it (bio/mech filtration), and the flow you will have with the pump you choose..... Ive seen 230's running 35 gallon tanks no problem with heavy bio loads..... Quote Link to comment Share on other sites More sharing options...
hustler Posted November 15, 2010 Report Share Posted November 15, 2010 (edited) The trick would be to use jap mats with foam sponge, ceramic rings and or Ultra bio media (anything with high surface area) and the biggest pump you can afford and you will be set. The more compartments/baffels you have the better you will be using the space in the sump as well as better oxygenation for all the bio media I am still switching my media over but the tried and true scrubbies still work too My 180 gallon sump My 300g sump Edited November 15, 2010 by hustler Quote Link to comment Share on other sites More sharing options...
