Consensus of overflow placement

Hi, I’m in the process of having a custom 75g (36”L x 24”W x 20”H) acrylic made. I am wondering if there’s a “rule of thumb” on where to have the overflow placed. Left back corner? Middle? Right back corner? Are there any advantages/disadvantages on any of these locations? I want to make sure that I have everything right before I give my plans to SocalCreations.
 
IMO, Left if your left handed. Right if your Right handed. <--Your sump can be the type were its


|___Drain-Skimmer___I|_____Refugium____|I___Return___|


Center Overflow like me. You'll need to have a T or Y drain to seperate the drain ='lly.

|__Drain+Skimmer__I|__Return+Heater__|I__Drain+Refugium__|

Whatever you want really...

Check out www.melevsreef.com for sump styles...Your drain is what powers your sump. Makes it so much easier to enjoy your tank.

IMO:
If you place overflow on left side then return have to be on right side ,vice versa. So The flow will travel along the length of your tank.
 
I was thinking about center originally but then thought about the left side. It would actually make sense since my sump intake is on the left as well. Slight change of subject, Filter sock or no filter sock? I designed my sump and was wondering if I should allow space for a filter sock. Due to the limited amount of space in the stand I opted out of the refugium and will end up using a denitrator.

My current sump plan.

Yeah I can have a fuge in there, which was my original design but I was afraid that the fuge would be too small to be worthwhile. I think the total water volume in the fuge was 6-7 gallons according to my calculations. Is that big enough for a 75g display?
 
The stand will be 36" high. There will be room for bends to allow two drain outputs with a ball valve to limit flow to a fuge.
 
Personally, for my next tank I'm going with an external overflow. It'll give you more realeastate inside the display and not take up much more room on the back of the tank since you're going to have return pipes coming up from the sump anyways. It'll give a much cleaner look. Check out

Also, I'd go with a separate fuge in case you have to service it you won't be stuck under the tank stand for a lon time. Besides, it'll make a pretty nice display if you keep some invert in there like hermits and shrimps and keep the algae trimmed. People prefer chaeto, but if you plant some caulerpa and keep it in control it's actually quite beautiful to look at.

You never posted a link. I want to see!

Yeah external overflow is absolutely on my mind. Are there any risks involved in having it external compared to having it internal? I'm really into the clean look as well since what I've had in the past 6 yrs reefing is a 40g UniQuarium which doesn't allow me much options. This will be my first "real" set up with filtration under the tank and I want to get everything correct and planned out ahead of time so I don't have to kick myself in the ***. Any help by you guys with this type of filtration would help me a lot since I don't the little tricks you guys know.

I can't go with a seperate fuse since I don't have enough space length wise. The tank area is in a recessed corner in the livingroom. It used to be a closet that I had converted to a tank area 2 yrs ago when I bought the house. Here's a pic to get an idea on what I'm talking about.

Behind that back wall is the guest bathroom. When I first saw this, first thing came to mind was OMG IN WALL TANK! But my wife didn't seem to like that idea. Oh well.

Here's a couple of sketches I made with the same dimensions as above but with a refugium added on. I took this design from another person on a different forum and modified it. Please let me know what you think.

Sorry, I thought I had bookmarked the link, but no can do :( I'll keep looking for it. Someone who has a link for external overflow tank please post also.

The sump, I'd avoid having the fuge output going into the skimmer area, you'll be skimming out the pods. And don't have it go directly into the return area or you'll have bubbles. It's best to have a set of baffles for the fuge output also.

The fuge is seperate from the skimmer area and does not flow to it. It only slow flows to the return area. The fuge will be fed from a T and a ball valve from the main drain to restrict flow. The other portion of the T will be feeding the skimmer area unrestricted.

Updated, tell me what you think.
