Never did post up for my 30G cube..
MP20 = 2000GPH
Return = 500GPH
2500 / 30G = 83x TO...
Got my 105G coming this week though and this is my plan for that:
MP20 x 2 = 4000gph
Koralia 3 = 850gph
Tunze 6045 = 1200gph
Return = 500gph
6550 / 93.5G (act. water volume in DT) = 70x TO
If the sand stays put with that setup, I might add a 2nd K3 or 6045...
