One thing to consider about noise in a overflow section or box...
..."if you hear noise, your kinda' doing it wrong".
Research the quiet mods for both Bean-Animal 3 pipe and the Herbie 2 pipe.
Even the quiet ones have noise when improperly adjusted
Learn how to do it correctly.
The quick ball valve with a handle will allow for quick shut off of a pipes flow.
The gate valve is the one with the threads for tuning like a garden hose shut off valve on the side of most homes.
The gate valve is truly the one needed for the tuning.
A ball valve is just there for quick shut down.
Remember to properly size the main gate valve so that the pipes water is running down a pipe that has an open path tuned slightly down from 100% full open.
If your pipe has a huge oversized gate valve, then the pipe may have to get turned down 50-75% and that would create a "ledge or shoulder" for things to sit on if Murphys Law ever came in to ruin the day.
A pipe that is turned down 5-10% should not have a such a big shelf to catch anything running by such as a bunch of plant material and snails.
Make sure to have screen properly placed before the pipes on some systems to catch snails and leaves.
A paint strainer bag of the 50-200 microns placed on the tip of the main drain like a condom will catch all that you need before in hits the first chamber of the sump.
A filter sock is just a pain in the rear in my opinion.
The thin strainer bag can be rinsed in seconds or rotated out with clean bag #2.
The main part of the sump can have lots of open porosity foam for the biological heart of the system.
The last chamber can have the fine foam or media for cleaning out more often.
When properly made, the sump can run very silent and easy to maintain.
Make sure not to trap yourself in a corner by cramming too much in tight spaces.
I was running a Deep Blue 80gal. rimless with the main Gate valve drain being a 3/4 inch turned down slightly on a Ecotech Marine M1 Vectra 2,100 gph DC powered sump pump.
One the way down, the ball valve above the gate was a 1 inch because I liked the way it felt as for usage, but could have been a 3/4 inch too.
The 2,100 gph pump was running at 50% and sometimes around 90%.
If the high flow is too much...don't turn it down in my opinion.
Learn how not to shoot the return water in such a nozzle-like stream and test different diffuser-style fittings on the output end to calm in down.
Keeping the high volume turnover rate will suck in plenty of unwanted detritus in the water column.
Tunze makes some expensive whisper quiet wave pumps that will help with deadspots in the tank and can be shut down with a feed timer build into them.
I tried the $125 Tunze brand model 6040 water mover and have two that work well.
The Tunze model 6020 ($40) with no feed timer had trouble on restarting.
They can be shut down for feeding your fish while the sump pump is left on.
Some sump pumps can have feed timers, but that usually leads to more stuff to talk about.
As for quality valves, the Home Depot/ Lowes/ hardware store trash valves are hard to turn.
Look into companies Like spears and Cepex for truly a better product.
I wanted to have a future dream peninsula build with a tank that looked like it was out in the room more as the sump was hidden in a box behind the rear of the peninsula.
The top off water and space under the display would house a crud ton of water for most of the water changes etc.
Below are some of my favs from the photo bookmark collection for future ideas.
