Return or closed loop manifold

I had been asked for pics of the return manifold so here they are.

In short, on the other side of the wall I split the return to 2-1" hoses which reduce down to 3/4" just before the unions. Then there are 2 manifold feeds. That loop connects all the way around with 9 pvc T's. Those pvc t's are 3/4" on the 3 sides but the T off of it is threaded 1/2". On those I have locline w/o any actual lines, just the beginning one with threads and then the small sized fan output.

Right now I have only 4 of them with the locline outputs and 5 with ugly white pvc 45's and then a cap on those with a hole drilled in them. I went to GWA last night and scrummaged but they only had 4 that I could make outputs with and had to order from premium aquatics the other 5.

Here are the pics:

Showing the union coming through the wall on the left:

Shot from one end to show most the structure, the other end is the same:

Showing what sticks down into the water. Note the pic is close up and I only used the 1 1/4" fan to keep the amount sticking in the water to a minimum. On overall view of the tank you really don't see them.

One nice thing about bringing the return over the top is it free's up both bulkheads for returns. Thus having more drain available than I even send up there and less chance of clogging etc.

The drains are the standard aga 1 and 3/4" with the 3/4" not having a stand pipe and the 1" having a durso on it. By the 3/4" not having a stand pipe it "should" keep down debris etc. by having flow in the overflow box down low. If the return pump would be too weak then this would keep up with the pump and make noises but I overpower it and it comes up and runs on the durso.

This works great on closed loop systems too btw.
 
I havent' cleaned those in awhile! :lol: Also, when I drained the old tank they were out of water about 6 hours and all the purple started dying off so they were flaking at first. Now they're just ugly. I think I'll clean them this eve.
 
Oh, the return is an Iwaki40 but I'm going to get a bigger one I think. I split it and it also feeds the frag tank but I have that output slowed down with a gate valve. I have this one on a gate valve but it's wide open. I wouldn't mind also having the main pump feed my phosban and carbon reactors too. I'm thinking about maybe something in the Iwaki 70 or 100 size. I have my skimmer on an Iwaki70 so maybe I could even incorporate that one into the mix as well and only have 1 really big pump.
 
Does the pipe seem to get in the way getting in and out of the tank?

Also does the flow seem to come out of other spots more than others not being controlled by a ball Valve?
 
Oh yeah Like the Magfloat SIEO Combo.. That looks like it works pretty good. What size SIEO are they?
 
Those are 1500's. There may be some difference in flow but not a huge amount. Either way it has a pressure and allows me to aim flow from different directions. Right now I have 2 capped off on the ends of the tank and just the 4 across the front and 3 across the back are open. That probably will change according to coral growth etc.
 
I usually use a vinegar bath and a stiff plastic bristle brush. This growth now has really jumped in the past couple of months. I've cleaned that one I think 3 times since the beginning of the year, mostly because I modded the mount one time and then the last time was when I got the magnet mounts and went ahead and cleaned them then too.
 
I use a 3:1 water:muriatic acid bath. I just drop the pump into it and let it run for 15 min. Then pull it out and toothbrush the outside off. Drop it in and let run another 10 minutes or so and then put it in a saltbucket of water and run for about 10 minutes. I try to do that every couple months and maybe every 3 or 4 times I'll also pull the pump apart and clean the insides with a toothbrush too.
 
I got it at a pool supply store on the NW corner of Lindbergh and Gravois. I happened to be at the St. Louis Dart shop and looked over and walked to it. I think I saw some at Lowes but I only glanced over at them as I went down the aisle so it may have been a different acid.
 
Looks good Roy. I have been thinking about building something similar except breaking it into 4 sections for my ocean motion unit.

How is the ETSS on an iwaki 70?
 
You can get muriatic acid at just about any hardware store. We, err, I mean, those pool companies will bend you over like a congressional page.
 
Much better. I'm getting a good amount and I fill the scrum bucket (I believe it's the one made by them) every 4 days or so. I need to get out the measuring cup and see how much that is. I think I'm using a little larger pump than I would have to in a normal setup because my pump feed is up and over the sump. So I imagine there's a little bit of flow loss from that. Possibly only doing as well as a 55 if it was fed in a normal way through the side of the sump. The body of the skimmer toward the top gets pretty dirty as well as the collection cup on top. So I have to wipe it when I clean the cup. As thick as it gets I feel like I'm wiping the A%$ of my fish. It did nothing for me in that setup with the 40.
 
The pump seems to be the key with these. I run mine up and over with a panworld 200ps. Due to overflowing issues I no longer run it as hard as I used to. I now get about a gallon of skim every 4-5 days.
 
I made little marks on my scrum bucket for cups and it looks like 1 cup today off a fresh clean.

I told you I'd clean it! :D
