Flow recomendations for my 120 (with diagrams)

[wetWolger]

I am not sure what flow setup I should use for my CL. So maybe you guys can give me some suggestions. Ether way the pump will be a 950gph pump that I already got.

The first idea is using a SCWD. I know about all the people who have had there units fail and all that. I am not too concerned with that aspect. But it would have 1 of the cycles for the SCWD output next to my overflow (the yellow box in the diagram). I think it would most likely point almost straight forward. The output for the SCWD's other cycle would be 4 nozels that come off the center brace. Two of them would point to the short ends of the aquarium. The other two would be at a 45 deggree angle so that one of the jets will hit the current from the sump return.

The second idea would use a deice there was a resent thread on (thats what got me thinking about it all)....it is like a seaswirl

There are a couple spots I think I could put this. Spot A, and Spot B. The areas it would cover are within the square on the diagram. If you like this idea let me know what spot you think it should be in. My biggest concern is having a little over 900gph coming out of one 3/4in outlet. The scwd would have that in 1 cycle, but in the other it would give a nice disperced flow.

Any ideas are welcome, but I do know that I want some sort of wave action from the CL. The sump is about 700gph and with this 950gph pump for the CL I hope to have all the flow I need, so also consider that I will need compleat coverage with what ever option (don't want any powerheads). Thanks for the input

A 120 is a nice size tank, but what do you plan on keeping in the tank? I personally think you might need to up the flow in your tank for a reef. A fish only or some soft corals shouldn't be a problem though.
With that said I think the scwd is not appropriate for a tank this size. Its only going to reduce your pumps output even more. The wavysea looks nice and would be much better if you had more then one and a larger pump. The you could split the pump to two wavyseas.
I personally use a www.oceansmotions.com unit and it works good also. I also have 10 different outlets in the tank to spread out the water flow so its not so strong from each nozzle. That's just for the closed loop plus I have 2 more for the main return. I use a mag 12 for the return and a sequence DART for the closed loop. That's probley around 3000-3300 GPH actual.
It really depends on what you plan on keeping. I think you might have 1000-1100gph actual with your current setup idea. That's less then 10x the turn over rate. The more you can spread out and increase the flow the better you'll be.

it will be a mostly softie tank....with a few choice placed SPS....sorry should have said that earlier

Heres a pic to give you some ideas to where the outlets are. This was before the tank was finished and running.

yea, i don't have the $$$ right now for a super amazing CL. The sump 750gph is giving a ton fo flow right now anyways. I am accually worried that the 950gph will be too much flow for some of my softies. I would like to wavysea but I can't aford that. Maybe later I will be able a second if I am not getting enough flow. But right now that wont work.

Any input of having the whole 950gph come out of the single 3/4in nozel of a wavysea?

Well then i would just add what you have to the tank then. The flow you have now is not going to be to much for softies. I have plenty in over 3 times the flow. I wouldnt put the scwd tho. I would just hook up the closed loop to 2 different outlets and probley would also put the main return on 2 different outlets. That way you will spread out the flow. Aim some of the nozzles toward the glass or the other nozzles to spread it out and create diff water motions.
