GPH?

you just cant argue with this mans logic !

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.

Im maybe 2x per hour if that. Its the electrically cheapest pump I can run from my basement sump to my display.

I have had reef tank for 6 year 6X Turn over is good.

What is the purpose of the refuge? Nitrate reduction or pod production?

As you are setting thing up just make sure you have enough room to vacuum out the skimmer and return section . Diatoms collect there and it's pain to clean if you don't have enough space.

Post some pics

In my refuge I have gorgonians, seahorses, a box fish, lots of LR Rubble, Macro Algae, some frags.. It has a very nice, slow movement.. It's purpose is just filtration & growing of cocapods <- don't mind my spelling.

As already stated, 6ish gph is a magic #, but that's based on info I've only read here in the past. Having enough flow to feed your skimmer is the point, without overdoing it

Unless I missed it, what I haven't seen mentioned yet is GPH in the DT, and this will depend on what coral critters you plan on keeping
