Help with sump

[Tankr75]

Hello I am attempting my first diy fish related thing lol. So I am curious about baffles in my sump. I am aiming to attempt the triton method with a diy sump. I have a dt of 75 gallons and and using a 20 gallon long for my sump. My questions are do I need to have a baffle in between my skimmer and return pump. If so how many. Also if I need to have some in between them how do I control the water volume in the return pump section. I have some photos attached of my sump and I apologize for the glare off the tank. The first baffle is siliconed in place the other two are not and that’s why there not straight up and down lol. Any feedback is much appreciated and than you for reading.

Yes, you should have an "over" baffle between skimmer and return because you want a constant water level in your skimmer section. The return section is the one where the evaporation will show and where you put an ATO if you are going to run one. The height of the baffle should be around the height of what your skimmer wants, at least not any lower.

Ok thank you for that I will get that baffle put in today. And I have another question about the return pump. I purchased the jeabo dc 6000 and the pump came with three different size return line barbed attachments is there a reason to use a smaller one vs a bigger one or vice a versa. Sorry I have never plumed anything before. And my last question is I’m building a diy pvc overflow and am using the design by Joey Mullin when he talks about flow rates he says a 1.25” pipe will get x amount of gph flow through it but they never say if that’s inside diameter or outside diameter would you have any idea about that.

The reason to go with a bigger diameter pipe from a return pump is to have less loss of flow due to friction, etc, etc. So if you for instance have your sump and return pump in another room than the display tank you could choose a bigger diameter pipe and not lose as much flow as you would with a smaller pipe. If you're worried about flow go bigger, otherwise go with 3/4" all the way. If you're going to use loc line at the outlet in the tank that is 3/4" too. But you can go bigger and then just put a reduction on the pipe to mount the loc line.

The one I've seen Joey build was a Herbie style overflow, with two drain pipes. Google that for a lot more info on how to set that up. But usually when you talk about pipe diameter you talk about the inner diameter. Different materials and qualities have different wall thicknesses so the outside diam can vary. There's flow charts for pipes you can reference. Just remember that what you should look at is flow when it's gravity fed under low pressure. In high pressure the flow is a lot higher naturally and not what you would see in an overflow or even with our normal return pumps.

For 1" pipe that's gravity fed: 960 gph
FOr 1.5" pipe that's gravity fed: 2100 gph

If you're making a Herbie style overflow you should choose a pipe that can handle ALL of your flow by itself (and then some) even if you have two drains. One of those drains is more of a security/back up drain.

Ok thank you for your help I appreciate it. And is this the herbie style you mentioned

No it's not the one I was thinking about. Can't remember on which build he used a Herbie but I know I've seen it. For the 375 he did a Beananimal style. To run a Herbie you need to drill your tank in some way and not go over the top. Going over the top has some cons and even if I know people use them I wouldn't feel safe enough with one. If you haven't yet set up your tank with water I would recommend drilling it now while you can do it and do a proper overflow, either Herbie or a Beananimal. Those are really safe and they are really quiet.

Oh ok. Well unfortunately it’s a tempered glass tank and I am in able to drill. And it’s also got all my fish and coral already inside it lol.

I was running a tom rapids pro rp3 wet dry filter on it and after a year the return pump went out and I bought a replacement pump and it lasted two weeks and I got a third one and it lasted almost three weeks and they kept flooding my floor so I decided to go with a sump and a dc return pump but honestly can’t dish out 100+ for a HOB overflow lol (wife’s going to kill me when she sees the skimmer,lights, return pump, and all the other goodies lol)

Ok, I get it. I can't really give any advice on over the top overflows as I'm not really familiar with them.

Are all of your panels tempered? You could make a diy overflow box for far less than they cost to buy pre made. But it would require drilling the side of the tank...
