I'm leaning towards the Dart not being to much for the return, since planning on the sump to be at least 48"x30"x20". The Dart is also going to be used to feed (2) reactors as well.
Crusty Old Shellback any pics of your sump to give me some ideas??? Skimmer wise for the tank I'm planning on the Reeflo skimmer....Still haven't finalized the overall tank dimensions as of yet, but considering going 60"x48"x30?
Mflamb and Nautica4 does the 1250 transfer much heat to the water?
