Gravity feed?
Ok, any help would be great, the image below is not to scale and there is more too it but I want to make it as simple as possible.
1. Tank is a wall divider, the returns and drains are on the left side. 2. There is a sump with socks on one side and the pump located on the other side 3. Far right is the refuge. In the drawing the refuge is gravity fed with a hose going back into the the sump once the water is a certain height, there is a ball vale to adjust flow... question, is this the best way to do this? any other ideas? should i add anymore ball-vavles etc to this? |

My suggestion would be to have more than one drain back into the sump in case one gets clogged.
Currently in my tank I have a temporary setup (old sump/fuge cracked) that feeds the sump from the fuge via a HOT overflow. The way I have it set up, even if the overflow fails nothing will overflow but the pump might run partially dry. But I used this overflow on my old 55g for years with no problems so I'm not worried.

I agree, have a backup drain. Also with your design it looks as there is no bubble traps or any other sections in the sump. This can cause a problem with the skimmer. The skimmer will skim out what the fuge puts into the sump. I myslef would like to have a seperate section for the skimmer to help divery and break down bubbles from the skimmers drain, and another section for the return area. I would drain the fuge into the return section of the sump.

You make a good point, and i do have two drains however i put only one in the image just to make it easier to see. So one drain just goes into the sump and the other t's off into the ssump and the refuge, does this setup seem optimal.

You are best to t off the main drain line with two separate ball valves--this way you can adjust the flow individually for the sump and fuge:
My set up is similar to your drawing just in reverse: its hard to notice but the fuge is gravity fed back into the sump

I suggest putting the fuge first in the sequence. You will want less flow to it than the sump. With the sump first, all the water may drain there leaving nothing going to the fuge. With the fuge first, you can adjust it to the corect setting and then let everything else go into the sump. Personally I don't use filter socks because they can decrease the number of pods since many get caught in the sock. They also need changed often and I don't want to deal with that.

Its going to be pretty hard to do that, how would you plumb that? Would i have to put the sump on the left side??

Quick update.
Here is what I have now. Let me know what you think. |

I thought the same thing about the filter socks so I removed it for 2 weeks--big mistake I am now dealing with cyano in the main tank and the fuge I was also corrected in the "misconceptions thread" about the sock removing too many pods--it doesn't: http://www.reefcentral.com/forums/sh...1#post11414721

In this senerio--the flow is greater through the fuge so its function is more for filtration(the chaeato you put in removes the phosphates and nitrates. In my case that I should you--my fuge is dedicated for producing a greater variety of inverts for the main tank. The flow is only 1/10 of the flow through the sump. I have made sure that the gravity return from the fuge enters after the skimming has taken place so inverts are not skimmed out. IMO the way you are diagraming it is a touch more complicated then you need I don't see why you have two return pumps --one is all you need Remember the flow through the sump needs only be between 5-10 times the total water column volume --where as in the tank it should be between 20 - 30 times the volume of the tank. In your case I would either run it with the water entering the fuge first then the sump where it is skimmed and then back to the tank. I either gravity feed with 2 inch lines or use a pump with one inch lines. or in my case the water is only t'ed off once with two ball valves--the greater volume going to the sump, the lesser to the sump One return pump. again only my opionion here.

to answer your question the reason for two pumps is the system is setup for redunducy, I have aa larger pump (1800gph) and a smaller (800gph) running on this system incase one pump fails.
What are youir thoughts on that? |

I have my old coral life 1200gph case that 3600 mag stops. Right now there are alot of battery backups for 80 dollars being offered up here in Canadian Tire. They will run a koralia number 4 for 8 hrs --which is more of a concern in a power outage then if your main pump is done it is more imporant to keep tank circulation going.

Ok I have been thinking about this for a while and maybe I'm just not getting it, I made another drawing again not to scale, also I didnt put the skimmer in or the baffels but labled them.
I'm trying to put the refuge first as suggested, so I switched the placment of the sump and refuge. Pros: The refuge has adjustable flow with the ball-valve and the rest goes to the sump. The refuge is gravity fed back to the sump after the sumps water has beed skimmed. Cons: More 90's on the pump side to get around the fuge. How does this look I'm a close? |

I'd suggest removing the socks, and use sponges on your baffles to trap debris. Socks can become nitrate factories, and trap those oh-so-precious pods that your refuge will be supplying. I didn't see anything wrong with your two pumps, so long as one of your returns can handle the overflow from both pumps pumping.

try to put as many unions and true union ball valves instead of regular ball valves. Later on when you need to service something, it will be impossible withouth them. A little more investment that will save you headaches in the long run

That looks like a good setup now--esp with the separte valve for the fuge and the gravity feed return. I'd leave the socks on until the refug is well established with cheato ect so it is helping with filtration. do you have an overflow in the main tank?

how much head pressure is there going to be?
Remember you only need 5-10 times the total water column in gph going through the sump or it should match the gph of your skimmer. The internal flow in the tank itself should be 20-40 times its volumne in gph which can be solved with power heads.
