Assuming the full volume of the refugium counts, you're closer to 6.5 times turnover through the sump which is what I consider "perfect".  |
probably a lot lower than that in reality, people over estimate there flow by quite a bit, not only the verticle hight adds head, the 50 gpr is not a good "rest of plummbing" figure. you can add 1 foot of head for every 90 degree elbow, add 1 foot of head for every 8 feet of pvc, this will also increase over time as you get crap built up inside your piping.
myself I like a 10x sump turnover rate and I design my sump to handle even more.
