Here is my first draft of the 100 gallon I want to build.
Tank 48"x21"24" (104 gallons)
Stand 49"x22"x37 1/2" (4x4 post(3.5"x3.5" actual))

What are your thoughts on the closed loop placement?
Two 1.5" outs and four 1" returns from an Iwaki 40RXT (1290gph @ 2')

Have a quiet one for sump return to two .75" returns (might get replaced to keep up with dual 1.25" dursos).

Let me know what you think.
Thanks
--Eric

looks pretty good to me, but wait for the real plumbing experts to chime in..

It sounds pretty good, but I would lean toward a larger pump such as a sequence or ampmaster on a tank of that size.

What is the rule of thumb when deciding how much flow. I dont want so much that it makes it hard for the fish to swim:D . I am also leaning towards the Oceansmotions 4 way for wave action, that might warrant a larger pump.

thanks for the replies and keep em' comming.

What it all depends on is what type of of biotope you are trying to replicate. If you plan on keeping fish, softies and lps corals, I am sure that pump would be very good for you application. If however you would like to have a sps dominated tank, a larger pump wouldn't be a bad idea. I am not saying that w/ the iwaki you wouldn't be able to keep the sps corals, they just would like the larger volume of flow, of a ampmaster or sequence. The nice think about the ampmaster is that it draws about the same current as the iwaki, but offers over 2 times the flow if my memory serves me correctly

I would eventually like to get to the SPS level of reefing but would start of with the softies and fish until I have perfected my water quality. I looked after your first reply and they do draw much less current and could double my flow. I just am not sure how much pressure would come out of four 1" outlets. It might be diffused enought where I am worrying about nothing. I also think my Iwaki has the American motor which from what I have read is not a efficient as the Japenese counterpart. I will keep a larger pump in mind though, thanks.

You could always run bigger plumbing and set yourself up for the bigger pump now, and then use bushings to reduce it to the 1" your pump needs. That way it would be easier in the future to just upsize the pump if need be.

Your plan looks great to me. I have to agree with Tom, a little bigger pump on the closed loop would be better. 4 outputs all at one inch will suck the power out of the Iwalkie. that and spray bars are flow suckers to. ampmaster 2100 sounds like a good size for it.

Thanks for your input, I was actually looking at that very pump yesterday. I am also considering using the 4 way Oceansmotions device but have some concernes about the short cycle between outputs or at least that is what I have read.

Would dual 1" drains keep up with the Iwaki with a single 1 inch return? Secondly I have an AquaC EV150 skimmer and the pump recommendations for that skimmer are a Rio 2500 and I am trying to get all heat producing elements out of the water. Could I split the return from the Iwaki return to power the skimmer and keep up with the dual 1" drains?

Thanks for all of your insight, your setup speaks volumes for what you know and undertand about this very diverse hobby.

yea they would. dual 1 inch will handle aroud 2000gph., I dont understand the single 1 inch return though? whats the plan thier.

I cant remember what the rio pushes ??? do you have that. One thing to concider with this plan also is that for the skimmer you want to pull the water from the area of the sump where the water first dumps in from the tank. thats where all the stuff is that you want skimm out.

I will have a one inch return come up through the overflow and then maybe split it into 2 3/4" outs on either side of the overflow box. This would be my insurance for a power outage or pump failure. :)

I think the Rio 2500HP pushed around 750gph. Good point on the skimmer pump location but then that leads me to having 3 pumps!! I guess if you going to do it, do it right.

Sump design for 120.

I have finally surveyed all of my "stuff" in the garage. Here is what I think I want to do for a filter on my new setup. Please comment on all aspects both good and bad.

Thanks.

Eric I dont think that rio will run both skimmer and return so another pump for sure dedicated to the skimmer. On your plan if I read it correct (refuge on top of sump, all water though the refuge then to sump) is that the way it worsk???
