I am ditching my too-loud Iwaki MD40 RT external pump. I just bought a quieter external pump, the Reeflo Dart 3600. My Dart pump should arrive in a few days. The Reeflo Dart 3600 pump has a whopping 2.0" inlet, which allows it to take in a fair amount of water with each gulp. By contrast, the Iwaki MD 40 RT has a .75" inlet, which is kind of cramped and water-noisy.
My system: I have two small aquariums draining to, and receiving water from, a common sump: (a) a 28-gallon Nano Cube; and (b) a 14-gallon Bio Cube.
Question: should I upsize my sump drain hole to accommodate the larger plumbing inlet of the Reeflo Dart 3600? Currently the sump drain hole, which leads water to the Iwaki MD40 RT pump, is 1.5" in diameter. It's a cinch to re-drill the hole. I have a glass-hole cutter. I could drill the hole to a 2.0" diameter. Then I could run a drainline staight to the pump, with no downsizing in diameter. (Compare: currently, I have to downsize the drain flow from 1.5" to .75" to accommodate my Iwaki.)
Alternative: or should I just leave the drain hole of the sump where it is: at 1.5", on the theory that my very small system will do just fine with 1.5"?
I like the idea of a monster 2.0" drain hole to evacuate more water more quickly from the sump to the pump, to avoid any hint of water congestion at the pump. But what do you all think? What are the pros and cons?
Thanks.
