Easier and doesn't hurt as much!

Not a bunch of pics yet but...A few for advice. This is what Im thinking for the closed loop outlets. Would the 90 and then 45 coming off of a 2-1.5" reducer kill a lot of flow? How does this look design wise?

I'm not 100% positive on this but I think you will get a slight pinching effect, but, I think you actually want this because of the multiple outlets. You want the manifold line to be slightly pressurized so that each nozzle outputs more or less the same flow as any other. Otherwise, water will just mostly go out the first nozzle and the further away each nozzle will have less and less flow.

Overall the multiple outlets will compensate for each individual outlet having a slight reduction, so it's not like you're not getting the most bang for the buck on the pump.

Yeah thats exactly what I was thinking. Each outlet will get that slight pinching effect but after thinking about it, I thought that might help, especially because the pump is fed up on the right side. I was worried that most of the flow will be just the right. I still think the right will get more flow from the closed loop BUT the return from the sump will be on the left and should even things out.

Anyways, I hope this works because I am out of ideas if not and I really like how this looks...Or really how its not very noticable. The ABS is very easy to work with and is much smaller and thinner than PVC. Already black too!

If anyone else thinks theres a problem though, can you please let me know soon because I want to cement the parts that will be cemented. I should be able to do a fresh water test of the whole system on saturday!

Looks good. But, I wouldnt rule out the possibility of having to go to even smaller nozzles. Basically, to pressurize the loop a bit, the are of all the nozzles will have to add up to less than the area of the feed pipe. You might even get good results going to 3/4" outlets?? Freshwater test will tell you, and as long as you dont cement the nozzles in, which I wouldnt anyways for cleaning purposes, you can adapt down to smaller real easily. I'd fill tank to just below nozzles and try it, if your drain/overflow will allow that. That way you can see the water coming from each pipe easily.

Yeah I can probably fill it a bit lower for the test. Im not so sure about anything lower than 1.5" nozzles though. I really don't want to reduce from 2" to something like 3/4" or I may as well have used a much smaller pump too. I think this pump at 6000 GPH can give good flow to all the outlets even at 1.5". I could be wrong though.

The nozzles will not be cemented in either because I do not want them stuck in one place. The tank is so shallow that Im sure this will give more than enough flow to the whole thing and then some.

Ahh yes, 6000GPH Somehow I missed that. I will be interested to see how she works Just got my top loop for the 45g done tonight. Most of the other plumbing done as well. Just need to find a reasonably priced 36" tank for my Freshwater fish, so I can steal their present tank for the sump LOL
