I have a RR aquarium (36'x18'x21.5', about 52 actual gallons) with a standard corner internal overflow box, I believe it is 1' out & 3/4' in. It has 5.5' of open teeth space and I will be using the oceanic trickle filter model 75, seen HERE. Going to be used for Cichlids (FW). I would like to add a under gravel jet system to aid in bringing the feces to the overflow and keeping the rock structure clean.

I'd like to run the UGJ from the output pump of the trickle filter to eliminate extras IN the tank. Does this sound reasonable? Should I run it from the output's default height or could I drill a hole lower in the overflow box to reduce head loss and hide the output behind the rocks? I'm thinking the overflow itself services the surface water and the trickle filter oxygenates the water so a low entering output should be fine and a DIY bulkhead would keep the overflow box water tight, also pluggable if I changed the setup. My real concern with this is ensuring the flow from the filter is enough to make the jets effective without overloading the overflow. Should prove interesting as a complete upflow setup.....

What size pump? Of course this depends on whether I do the output at the top or lower but I am aiming for the lower output. I can get about 300gph through the overflow teeth (I think!) so I am thinking something like a rio 1400 (420gph) after head loss from the height, all the elbows and about 5 jets should be about right.

I am pretty sure my plans will work but I have never had a sump or W/D type setup before and I of course want to do it in a complicated way! :D
 
According to the head loss calculator at reefcentral.com I may need more like the Rio 2100 (692gph). My results But I don't think that is actual accurate considering my unique setup.

Aww, come on, nobody? I know you guys must at least have SOME opinions on this. I think it will all work great and is very doable, I just wanna know if you guys agree and I just like talking about this stuff but I need someone to talk back! :D The pump size is the only thing of difficulty, getting the perfect size pump seems to be impossible because of all the variables. Easy solution, a valve on the return line of a slightly over sized pump.
 
so you are planning on routing the existing out flow to run the UGJ? sounds doable.
plenty of DIY UGJ set ups ou there..

I say go for it and adjust as needed.
I guess you are planning on building out the ugj frame bury it in substrate and place jeta along the perimieter.
 
Yes, frame, substrate, perimeter, you got it. I've made the UGJ part before so no trouble there it's just the other details that are slowing me down.
 
drill near the bottom of the overflow panel run 90 to the plumbing from the outflow pipe?

question would be how large a pump....
you shooting for around 10x turn over?

Yes, I will try to do a 45 if I can.

The overflow box can only handle about 300 gph so I am shooting for as much as the overflow and drain pipe can handle. The drain pipe can handle more like 600gph so I could modify the overflow teeth but since the entire output will be coming out of the jets I also do not want to make the jets too strong. My old UGJ was about 84gph per jet and even the furthest from the pump would still have quite a bit of push when a fish swam by.
 
sounds like yo have a plan..

I would go for it ..set it up sans the substrate and test.

personally I would modify the overflow to handle more
