![]() I would go as big as you can fit/afford. The bigger the sump the better. More water volume means a more stable system, more space for skimmers, reactors, heaters etc. I have seen some tanks where the sump is actually bigger than the display.
More water does have a down side though, it will cost more for salt and electricity to heat/chill the water. But to me the benefits of a larger volume sump outweigh the disadvantages. |

![]() go big, even if you can get it bigger than your display. I have a 70g under my 180g and im still drawing out plans to build a shed and have a massive 300g or something setup for my sump. ive ran out of space and i cant even put my reactor in with my 70 but then again i got tons of live rock so its filling up my sump.
