cheers, Charley

no... I rarely if ever recommend drilling the bottom of an aquarium. Undue risk and no practical service in most cases.

Feed/flood the pump from a 2" bulkhead that is about 1/3 down from the top of the tank. We don;t want to go down any further than we need to be safe in case of a bulkhead leak. But we do need to be down low enough to prevent the strong pump from sucking air.

As for the Dart on a manifold... do see if you can get at least 400gph from each 1/2-3/4 outlet (more if you are using larger tees). And see if you can come close to having one tee per ten gallons of water on the manifold loop.
