also can your tank overflows handle the 3000+gph? like your plan shows, most overflows are rated for 650gph

My current overflow is 650gph and I just bought a dual 1"overflow that I believe is 1100gph so both together should be fine if I do as you said with the reactor water going back to the first chamber of my sump? Correct? Plus it's a dc pump and I don't plan to run it full boar.

in my 180 I have a rio hf 2600 with head pressure it is pushing around 1300-1400gph into my display even with mega flow pipes on my rr tank it is loud from the amount of water running threw the 2 pipes
with your tank I wouldnt push more than 800-1000 gph threw dual overflows this will let the water spend more time in the sump getting polished and give time for large particles to settle so you can manually remove them
more often than not ppl try to get flow from there return this causes allot of "what ifs". usually "what ifs" cause lots of problems in the long run

The way I see it is if I run the pump at 75% it'll be 2300gph and half that will go to my reactors to get recalculated so I'd be looking at about 1150 going back into the tank at anytime witch is about where I'd like to be.
I'm sure that number well be a little lower with head pressure and when the pump slows after time.

imo- still to much for a 75g.
I would keep return flow around the same as your skimmer,reactors. all about 500gph so they all have time to work like they are supposed to....
I referenced my 180g because 1300gph+ is to much I couldnt imagine that much flow threw the sump on the 75g display

I use a reef octopus water blaster 5000, that's rated for 1300 gph in my 90. I like it better than my the hydor that's rated for 750 gph on my 40 frag tank. But a good pump is going to be more true to the gph and head loss. I don't think I'm getting anywhere near 750 gph in the frag tank and the water is too clean in the sump and not so clean in the display. I'm having nutrient problems in the frag tank and dying cheto in the sump. I need more flow. But that's my story. Every tank setup has different stories. Only problem with higher flow through the sump is the noise. I was told i need to get the tank out of the living room.

As always I'm the exception to the rule. Water blaster 10000 -2600 GPH pump, same pump I had on my 75 gallon pushing water through my 40 breeder sump and the only noise is usually my pro tine skimmer humming. Just proves that every system is different when they are setup by different people.

More flow, More flow and more flow!!! That's what I want more flow:)
I think I'm going to buy the dc 9000 it's flow rates are 2,377, 2,136, 2,020, 1,901, 1,663 and 1,426 gph and that's without the 3' head pressure. So weather I put it on 100% or 60% I think I'll be fine and I still have 4 settings in between.
Also thinking about Trashing the manifold and putting the Hydor on my bio pellet reactor. I'm going to be the guinea pig and try the new all in one bio pellets. So fingers crossed hopefully only 1 reactor.

biggest mistake newbe reefers make is trying to use there return for flow in the tank. (been there done that)
you want high flow in the tank and low flow threw the sump
by havng high flow threw the sump, it makes the skimmer and reactors about useless...
with 2000gph (or even on the lowest setting about 1400gph) going threw the sump how much of that water actually gets skimmed or run threw the reactor? with a skimmer and reactor that runs on less than 500gph I would say you are only going to be able to polish about 1/6th or less of the water after it leaves the display tank. not to mention the nasties will settle in the display tank instead of settling in the sump, making allot more maintenance for you in the long run...
all I can say is good luck!

I don't consider my self a newbie. I don't have the experience you do.
I know I have plenty of flow in my tank probably to much at times. I plan to reroute about half the flow from the return back into the first chamber allowing it to get a second chance at contact time.
At the lowest setting with head pressure I'm guessing the gph to be about 1000gph and with half of that going back into the first chamber that's leaving 500gph back to the display? Keep things moving and also allow for maximum filtration.
If it doesn't work I'll take it off line and go back but I have seen many systems with very high flow through their sump with great success, I've also seen many tanks with low flow through there sump and a tank full of algae and vice versa. There isn't a right or a wrong way imo.

not saying you are a newbe, just thats the plan for allot of newbe's to try and save $$ on equipment. then they give up in the first year because of problems...
not saying it wont work just my experience in the past 16 years... heck you can push all that flow threw a downdraft skimmer it will remove another pump (your skimmer) and the skimmer will keep up with the flow from the display
algae has to do with nutrients not flow

This is probably one area we will always disagree, which is perfectly fine. Regardless, even having the massive amount of flow through my sump that I do, my tank is pretty much clear of detritus. On the other hand my Super reef octopus 3000 skimmer fills the cup about every week or so with a mix of thick brown sludge and dark liquid. Everything else that it doesn't catch settles in the three chambers of my sump before heading to my main pump. I'm actually considering teeing off my return line with a valve so I can isolate my sump from the display tank and use toe full force of the pump to flush out the entire sump so that my skimmer and a filter sock can pull everything out when I want it to. |

Don't get me wrong I agree with the fact that your skimmer/reactors need contact time and I believe I'm getting that atm but from some recent things I've read doc (dissolved organic compounds) tend to float at the top with low flow and with higher current/flow in the sump doc stay mixed up in the water column. Now this is kind of important because my skimmer like most I'm sure pulls water from roughly 8"below the surface so if doc stay suspended on the top portion of the water my skimmer won't get most of them the first time no matter what but if I'm recirculating water back from the end of my sump back to the front that should give second contact as well as mix up the surface of the water to allow my skimmer to pull as much doc as possible??
Isn't that why overflows take water from the surface of your tank? Because that's where proteins,doc and other nasties settle?
I love the debate though it's awesome to get some discussion going and healthy debating is never a bad thing imo. I'm talking about things I've read and want to try because I believe they make sense, that doesn't make them all right:)

I have never seen fish poop or left over fish food float....thats why wr get "dead spots" in the sand bed from low flow
with high flow in the display,solids get mixed in the water coulmn for your skimmer to remove them with low flow threw the sump what your skimmer dosnt get will settle for manual removal.
high flow threw the sump means solids will stay in the water column and get returned to the display till they find a spot to settle

Any thoughts on putting a jebao dc3000 pump on my sca-302, external? Kinda like the reef octopus?
