Ok what kind of design do you suggest? Three chambers? Two small ones at the end 18" each for intake and outake? And on large one in the middle for the sand bed, rock, and macro algae?
Also I got a concern, with this drilled, if the power went out then the overflow would still pump out water into the sump, but no water would be pumped out of the sump so that would cause an overflow. Should I just pump it into the sump in case an electrical outage the room won't be flooded? By the way if the room did flood, I wouldn't be talking and my mom would be in jail, just to let you know.

No with drilled overflows it can never run over. Water only runs out as fast as it gets pumped in. Power goes out no water gets pumped up so there is no water to run down the overflow. You should really go to a lfs and see how it all works.

So I take it the holes are at the very top? Anyway to keep the water level not full in the sump? just incase?

No the holes are in the bottom then you out a overflow where the holes are. This is acrilic it has holes in the top of it. You build a standpipe off the bulkhead. Water can only get in throug the holes when the pump stops it run. Down until the water is through the holes than I can't get any lower. Heck give me 15 min and I will post some pics if I can find the camera.

Ok can't find my camera look some where you will find a picture and the you will get it or go the lfs and look at one.

Ok thanks Rslinger. You're saving me a trip to the lfs. And looking like an idiot, no offense to anyone who suggested that.

Yeah its all right but for real I could not understand how overflows could ever work until I saw one the it clicked in. You make your sump to run less then full so when you shut it off some water has room to run in. When it is shut off the DT will be a inch or so lower that when it is running but it can't drain lower than the holes. Also the water that is held in your pipes will empty in the sump. You will get it. When you see it you will be like oh it is that simple.

Hopefully. I just randomly figured out how the closed loop system worked dreaming of a huge shark pond one day. I said, oh that was simple then too. I searched for images and didn't get any that looked like what you're talking about on yahoo search.

Ok that kinda makes sense. The water goes throung the..., wait who am I kinding. That doesn't make a lot of sense to me at all. Can you go through a step by step of how the water goes through that? Where does it lead? To a sump below? I'm confused, but what's new.

Ok the black box looking thing is the overflow. there are like teeth in the top of it where water can come through. ok the pipe is he standpipe. the water goes down that and in to the sump the bulkhead is the fitting you use to keep the pipe water tight so nothing leaks around it. ok so the ater in the main tank cannot drop lower that the lowest part of the teeth. the reason the pipe is on there is so tall is for noise control you make he pipe so the water doesn't have to fall very far down from the teeth. when you turn the pump on it sucks water from the sump and puts it in the display. then when it gets high enough to hit the teeth the water flow back through them and into the overflow when the overflow gets full it emptys to the sump.and starts the procces all over again.
but for real they aren't kidding and either am i. i am not sure you will completely understand until you see it in action.

Ok well I need to make a trip to a lfs and get some algae sheets soon. I'll say I'm thinking of setting up a tank. Can I see an example of an overflow into a sump? Is that what I should ask? Also how quite is this tank. My mom is refusing to give up her daybead so it will likely share a room with that. Nobody ever uses it but if they had too, is it noisey? Or it may be in my room, I hope not but maybe.

Ok well I think I'm going to make the stand 5' widex7'long so the 125g sump is going to be directly behind the 270g. Will that be an easier? Oh also I got good news. It is going to only cost 100$ for shipping so the total is
$1,000 for the tank. I'm going to ask about it being drilled after I figure how big the holes need to be, etc.
Anyone got a pic of how there overflow works?

you realize what a tank and sump that large weigh right? you need it on a concrete slab, or one heck of a foundation

Ok so leave the 125g underneath? That will save me a lot of space so I'll leave it under. Kinda was thinking about that. What would the noise level be? And the pic that Rslinger showed me of a durso stand pipe, that's an overflow right? Is that different from being drilled? I'm soo confused. Can anyone show me by paint shop? Thanks Mike

Why can't it just have a drilled hole that water comes down to the sump by pvc pipe? Like this:
It wouldn't flood because the holes would be at the top so if the water didn't get pumped back up the water line would drop below the hole and the sump would be all the way full. How big and how many holes would equal 900gph? How can the pvc pipe stay in place?
