Less likely than an overflow design!! That being said maybe I might still do it!

DIY Over Flow design

Hydrocyanide:
that is my video.... I ran duel 3/4"overflow T-ing to 1 inch to the sump... It flowed 400 to 450 GPH. If i would make it again I would T it to 1-1/2" to the sump and it would have gotten more flow,, maybe 600 to 700 GPH ... Yes the shorter you make the overflow the less GPH you will get.... This one in the video was for a 220G tank... but it was my first overflow I made. I have upgrade to a bigger overflow... Dual 1-1/2" T ing to 2" with a flow of 900gph .. And yes it is short and doesn't run to the bottom of the tank.

Well thanks for posting it on YouTube for others like me to see 
I just wanted to make an overflow that doesnt take much space up in my tank and still has at least 600gph. That would be 6x turnover for my tank + 3x with my canister.. + I wanted to add current from the return enough to eliminate some of my circulation pumps in my tank and lower electric use from my tanks. I had and accident yesterday and lacerated my knuckle down through my tendon so I won't be building and putting sump up for at least 3 weeks! 
:thumbdown: the information ive recieved about sumps over the last few weeks, I feel capable of building a reliable sump and overflow! Thanks to everyone on MFK

This will be my design for my sump. I know some things will change but this is my basic idea. I've got the glass and acrylic pieces for the build. Waiting on the sock and I'll buy the pump when I know what gph I'm getting.

This is just my opinion.
1st The second chamber with the filter is gonna be hard to change.
And with the glass divider all the way to the top of the sump, if the filter on the bottom clogs you are going to be cleaning up some water off the floor.
2nd I have a 25G sump on my 220G Tank. With the unit running it takes up half the sump. When the electricity shuts OFF the overflow drains until it reaches the inlet of the overflow and stops. So My sump when the electricity shuts off is about 1-1/2" to 2" from the top.
When the overflow and pump are running the water level is about 1/4" to 1/2" above the overflow inlet. So when the electricity shuts off you need room in the sump to accommodate the water in the tank to the sump.
In your set up you have the Tank and 10G with duck weed so when electricity shuts off the duck weed tank will drain down the the outlet and the 100g will drain down to the outlet. So you need enough room for the water to fill the sump when electricity shuts off.

Thanks for the advice ruddybop. That all makes perfect sense. Its just a rough sketch before the final design. I drew that up in like 5 minutes to show my wife how a sump works haha! I do know that I will have to accommodate for the water being lost in the tank down to the sump, but didn't really show that In the drawing I made, so maybe for MFK purpose I could have drawn a better more thought out design haha! and the overflow obviously don't work the way I drew it. ill get the sump built and then add the duckweed tank after I get the sump up and running.
I do apologize for my absence, I have a bad habit of disappearing lol! not in my nature to do otherwise I suppose. I have all the gear except the return pump and a chiller to set my sump idea up. the only problem is Christmas and all the fun stuff I like to do during this month of snow and laughter. Ive drained my bank on tires, xmas presents for my kids and wife, and snowboarding gear. I would have had it all up and going but due to my figure being lacerated and loosing my tendon into my finger and hand, that pretty much halted my work on the sump and pretty much any use of my left hand. I assure you its not a waist to wait on me a bit longer, cause I will build it. Im currently in the process of building a water vat for my tanks. I use RO and with it -2 degrees here, its very hard to do an up to temp water change when I buy my water at my lfs in 5gal buckets. give me a month or so and this thread will be back up and running with my design. I am also just finishing college so my source of income will stop for about 3 weeks until my soon to have job pays me! ill be playing catch up on bills and my lively-hood for a bit before I continue and finish the sump build. Thank you for being patient as well as checking in to see what Ive come up with, I am sorry again for the long dely on getting back to this thread!! -Hydro
