How big??

[Mudbeaver]

-For a closed loop how big my holes for the return for a 100 G , and another 100 g seperated in two compartiment. plus a 70G sump.

- And for the intake how big should they be never done this any place i can find this info as well. Can't head or tail of this.

My external pump will be a Velocity T3 pump
Max Head 28′ MAX HEAD
Flow 850gph @ 0′
In 3/4″ MPT
Out 3/4″ MPT
Watts 140 WATTS

Here's the plan

I don't see a closed loop line, the one you have labeled as a closed loop is functioning as a return line. A closed loop will have the intake and output on the same tank. With the return pump in the sump, pumping to two different tanks, it is a return line.

Ok so i'm missing the intake line then? The pump is an exterior one a Velocity T3 pumps ;This Blue Line External Water Pump is the exact equivalent of the Poseidon PS3.
Its very very quiet and was recommended to me since my system is going to have 0ver 200 G to pump. so i was told to exceed that by far.

Where would you place the intake and connect to what the sump, do i bypass the skimmer? And go directly to the mid section of the sump to feed the pump if so how big the holes, thats my problem with this system i can't figure out the size and positions of those holes.:blown:

**** If you could copy my picture and use your paint programg and put it where you would think they should go i know i'm asking alot. Thanks for your time. ****And tell me the size you would do them.

The feed is under the overflow box 2 holes, and connects directly to the sump feed to the pump going to the return and loop, hows that. The color schemm could of been better but...

I would forget the closed loop, set it up the way you have it. For the return lines, go one to two pipe sizes larger than the output of the pump. Because of the tank on top of a tank design, make sure that the drain for the top tank is high enough to keep too much water from draining into the bottom tank and the sump can handle all of the water that will drain wi a power out. Same goes for the return plumbing, it must not be allowed to drain much back when the power is off.

Ok but this sucker takes 850gph it must be fed, so the drain should be bigger no?? or some kina feed right. Or my sump will be empty in a second.

Your drain will have to be able to handle the flow from the pump, I don't see the details on the drain so I can't help. If it is an open channel (air assisted) drain you will need a large diameter pipe, if it is a siphon the pipe can be smaller but you will need a backup drain as well.

It will be an open channel drain , i'll make it large then to supply my sump but the skimmer will have to be kicking too lol. I put a filter sock 2 microns at the end of my drain anyway it helps alot and change it every day amazing the job it does and it eliminates lots of bubbles and noises.

That would be the general desing; the overflow will be "L" shape and not "V" shaped , the box is external and the drain is as is.

One large one should suffice, now how large is my question, 2"- 2"1/2?

[sirreal63]

You have three holes but only using one as a drain? Are you going to cap off the other two? If using one, the 2" should be plenty.

I took this design from another post to show you the direction i going the box, the 3 conecting holes with the oveflow but their will be only one drain . So 2" thanks very much for your patience and info. I'll be using spawflex to reduce noise, do you have better?

The overflow is coast to coast going to an external box 30" long 5"wide 5"deep ;How low should i put the drain under the line.
