Need Some Drain & Sump Wisdom
- Thread starter ReyDeFarts

Thanks for the responses and help. I agree about the small drain with a valve will cause more restriction. I laughed at your response because of these two sentences! It's slowly getting there. We finally agreed on a spot where the tank is going!
Now to get it into the spot, redo some electrical to protect the outlet, level it out, fill it, and test out the drains.
After hearing to use the small drain as the primary, it definitely messed with my understanding of how they designed the tank. I'm still stuck on using the larger drain on the primary.
@Coral reefer I get what you're saying about not even using those drains and start from scratch with new overflow. Or get a different tank. We're doing this hobby on a strict budget to say the least. So we're trying to not go crazy with additional purchases. I have seen in other forums, some kickass setups with this tank, plumbed the way the way they intended it and sold to customers. That's why I keep going back to why not use the larger drain as the primary. Just trying to make this work with what I've got the best I can.

You can use the larger drain as the primary drain, but I would use it as a durso drain and not put a valve on it. Durso drains are hard if not impossible to silence though.
Thanks again for this Marcos. I forgot you posted it. I was curious last night about how to approach the setup for this. Definitely had it backwards in my head on how to use the chambers.
I think I will be adding some live rocks or media bags to the return area as was suggested. I'm not too sure about adding filter socks to this sump though. I'd rather have some sort of course sponge for mechanical filtration.
The past couple days I have been able to put in some time on the tank and prepped the area where it will go. What a mess!
Amazon did not come through with getting the 40mm x 1¼" adapter delivered though. So for now, the larger stock drain will have to do for testing.
Finally got it wet to test out the drains! The ½" is able to handle the full flow. So that's a big plus.
This appears to be the highest the sump will get. The middle baffles is what controls the level, correct? Is this enough sump volume for this tank?
In the return area, I used a Sicce Syncra Silent 3.0 to test it out. It was a bit too much flow than what the drain was providing. I tried it fully open and the minimum. I'll be ordering a new DC pump and installing a valve as well for further flow control on the return line.
So with all that said, I don't see why I would add any kind of valve to the small drain line if I were to use that as the primary since it cannot keep up with this pump. Now to wait for the adapter for the large drain so I can get that switched to 1¼" pipes.
I was able to test multiple positions of the return nozzle to let it back siphon and see how full the sump would fill. If the nozzle was pushed down too far, that would definitely become an issue. I think I'll be adding a y-fitting on the locline and reducing the length. Hopefully minimizing that hazard.
Any other considerations I should be thinking about?

The Sump needs enough volume left open to ensure it doesn't overflow with a power outage. Easy to test unplug return pump when tank is full and note water level in sump once it stops draining . If it over flows to much water, if not you can use that to figure out max water you can add to 5he system. I keep 3 inches from top of my sump without power to return.
The level of sump after return pump is running again gives me the water mark of where to put the ato sensor at. Most likely you know this already, just mentioning it because I had to figure it out from flooding my stand a few times.
I did test that out a couple times tonight. It never came close to the top of the sump thankfully.
I will have to get that figured out after I get the new pump then. Thanks for the info. I'm just now learning about how to use a sump.

You can increase the amount of water in sump if it's not close. I guess water level in sump may matter for skimmer as well.
Still learning them myself. Trying out filter socks this week. They clogged up on me so i swaped to the other pair. There are so many little things you learn from just doing it, that everyone doesn’t bother mentioning as it seems common knowledge to them. Watch a million videos get lots of advice and you will still have tons of on the job training lol.
Since i'm getting the larger tank I scraped my originally plan to make more rock structures to replace fake rocks in my 65gal. I finished the first one last week and today said screw it and tossed the other rocks I was gonna build the other structures into my sump today. Hopefully it will be well seeded for the next tank.
Can't wait to see your tank up and running. It's looking great so far.
Usually you want the sump water height high enough that you're not hearing a waterfall from the water going into the return, but low enough that water is pouring over the edge.
The reasons for having it pour over the edge are because that ensures your ATO is only refilling based on small water changes in the return section, and not the entire width of your sump.
For example, think how much water is in 1cm vertically of the entire sump, versus how much is in 1cm of the return area. You can do l*w*h math to know exactly how much, but it's a very big difference. That means if you lose a cup of water, your return section's level will lower a lot more than if your entire sump was filled and you took a cup out. That then means it's much more precise for an ATO to keep things consistent.
Other benefits include helping break micro-bubbles if you have a skimmer, another small bit of aeration, and a convenient, high flow, place to put bags of carbon and such.
The setup of the drains I won't get into again since I'm pretty sure that topic has been covered to death.

I appreciate it. This tank belongs to the wife. Lol. I'm looking forward to seeing her put together a scape with all those rocks we picked from you. After it's up and running, we'll get a proper journal put together.
Quick thanks to @Srt4eric for a great deal on a skimmer for this tank.
I had another sump sitting around that was going to be used for another build, but that may not happen any time soon. So I figured I'd pull it out and see if it would be a good option. It's a Trigger Systems Sapphire 26.
The drain is a 1" inlet. The nice thing is I have a gate valve I could use on it. So the plan is to get this plumbed up and test it out with the new pump.

That's the same sump I have under my tank right now.
