Need help understanding sump filtration please

Yeah I think thats what he meant. If using a diy overflow the T off the rise of the low U would be where the high U is in that pic.

After looking at the various styles of overflow, I think beananimal's provides the most peace of mind and would probably work for what im trying to achieve. The overflow wouldnt be very large and could be easily disguised or just framed out of sight if the tank ends up being in wall. A small price to pay for keeping a couple hundred gallons of water off the floor. As long as the tank isnt too tall, I could use a Calflo style overflow, but have it spanning the width instead of the length. The tank will likely be 72x30x18? Not sure on height yet but it wont be extremely deep and that much width should give a good amount of pull. I could always design the interior to have a lower flow area like a pool on that side. I know thats a complete 360 from the original idea but it will be a lot safer and probably easier. Not too mention quiet.

Guess I should have listened to blazingwolf in the first place lol

FOR PIECE OF MIND

i've been doing some research myself

do NOT be fooled into thinking a 1 inch drain line is enough. OVERSIZE
look up. myth of the one inch beats on google
and also bulkhead flow rates
wetwebmedia has some good writeups. AND i've found they are true. my overflow is sooooo much louder on my 75 gallon UNTIL i get the flow rates down to around the 300 gph range. same as my 29 gallon
this can be done with ball valve or by swapping pumps..
not only that but its killing my co2 consumption
so ima shoot for a 1.5 inch drain which should allow for a safe gravity siphon, with low noise, and less air actually being forced into my sump.. should result in less co2 loss, less, noise, and the same oxygenation benefits

i throttled back the 29 about 50 gph so that the line doesn't suck in tons of air, my co2 consumption dropped in HALF so, when ur building. GO BIG ON DRAIN LINES

thanks for the info. When i get around to actually building this monster, everything is going to be big. It will likely be in the 500-1000 gallon range, so the pipes are gonna be huge. Not worried about co2 since it wont be a planted tank, persay. Maybe some willow moss since its native to Ohio, but any other vegetation will be strictly riparian. The goal is to put a slice of central ohio streams right in the wall of my home. The best part is i get to catch all the fish.

It may seem a little far fetched but this is my dream tank and really my only hobby that costs me money besides fishin' lol. I love our native fish and love catching them. even if i cant keep them right now, snorkeling in rivers with nets all day is a blast and something i do every summer Gonna be a long time before it can be achieved but when it does.... its gonna be EPIC.
