GPH?

[mark]

Always found the idea of must have X.XX turn overs an hour or or must exactly match your skimmer intake pump little hard to believe. Where's the harm in having your return pump contributing to the overall flow in the display beyond some value through the sump no one can reach a consensus on?

I can a agree there's more efficient ways to get flow in the display than a return pump and so much through the sump you have to put brackets on the skimmer so it doesn't tip over, but I wouldn't be getting overly worked up about matching a magic flow number.

I have probably 4x turn over through my sump. I carefully calculated this based on the cleanest pump I had in my box of pumps, considering clean was more likely to work. MAG12 won, minus head pressure, plumbing restrictions and sludge inside pipes, I figure 4x. Or 5. Or maybe 3.87658. Basically water falls down, water goes back up.

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.

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
