Ok, while designing the sump/refugium for my new 150 several related questions have arisen and I'm wondering if I've got them right or not. First is line sizing: my drains are for 1.5" bulkheads & my returns are for 3/4" bulkheads, so 1.5" PVC in the input side of the pump & 3/4" PVC on the return side? What if I made the return 1" coming out of the pump?
Next, according to the RC sump calculator you get ~ 1300 gph from a 1.5" drain, so with 2 1.5" drains I'll be flowing ~ 2600 gph through the sump, therefore, in order not to flood my house my main pump (after head loss) needs to be able to pump at least 2600 gph, right? I was looking at the Reeflo Dart as my main pump at 3600 gph at 0 head. So, depending on total head loss then this pump should be sufficient, right?
Since I'm having my sump custom made I need to locate the hole for the bulkhead fitting coming out of the sump at the exact same height as the input side of the Dart so that my PVC is straight into the pump. Anyone know the height of the input side of a Dart so I can locate my sump bulkhead correctly? I'm asking because I'm probably going to have the sump built before I buy the Dart ...
Last question (for now): according to the RC calculator the sump volume needed to handle my tank overflow is ~12.5 gals and the min sum vol for my tank is 39 gals. I assume this number is 'total' including overflow? Also, what is a typical refugium size if your sump is 40 gals and is there any kind of sizing method for refugiums? (My sump & refugium will be physically separate tanks with one part of one of my drains as the input to the fuge and the output from the fuge will be an overflow back into the sump ...)
