Overflow Pipe Size and Return Pump on Custom 60 Gallon

[HandsyLobster]

Hi All,

Im in the process on building my tank and need to help in regards to what size bulk heads / hole size I should use for the over flow / return. Also for the return pump and recommendations would be great!

My tank will be a 30x30x16 with a 20 gallon sump. Im going to do a Herbie over flow that will be drilled at the bottom on the tank. This tank will mainly be a SPS tank so high flow is what I'm planning on.

Any Help would be amazing.

Thanks!

I would do at least 1" pipes for the drains and 3/4" for the returns.

That size pipe would be more then adequate for that flow rate. You'd have to dial in the full siphon drain with a gate valve reducing the size anyway but the emergency would be able to more than handle that flow with no issues.

I have a bean animal overflow setup with 1" drains. I would prefer bigger but it works. It handles around 800-900gph that I push through it just fine. For the return I have 1" pipe from the pump split via a T to two 3/4" inlets in the tank.

Perfect!

This has been a great help. Im planning on getting the

Jebao (DCW-3500) for a return pump rated to 900 GPH do you think this may be overkill as I want to run the pump at around 50%​

Thanks,

You may want bigger then that. You have head height to deal with. Total = hight + fittings + pipe size etc. That will reduce your flow a good bit. Probably like the 6000.

I had a Jebao DCT-15000 and ran perfect for I think 5 or more years. I took it offline to try out one of their new smart pump the EP-10000. I run my sump in the basement so have a couple more feet of head hight to deal with.

Gotcha! Thats a big help I'm glad I didn't order it yet. I'm going to look into their smart pumps.
