Sump help

Use the headloss calculator.

When in doubt go over and throttle back with a valve on return lines.

Youre looking at maybe a mag 7 I think with that overflow. Youre overflow will only handle as much water as what the pump sends up to the tank. If the pump is slower than the overflow then it will work still. But you are aiming for as much flow as you can get so yeah, measure out how far the pump has to push the water and take into account any bends or tees in the return line.

So I'd be better off with the mag 7 pump (700gph)
With a head height of 12 feet

I'm gonna use flex tubing so I won't have any bends and I have to pump the water about 4.5 feet vertically

Yes get the 7.

12 foot head height just means it can push water up a maximum of twelve feet before you there is no more flow. It starts out max flow(700gph) 0-1' and then every vertical foot after that the amount of flow decreases till it reaches 0 at 12-13' high.

Make sure you get either ball or gate valve in there so you can throttle the flow back to match your overflow.

Ok and yeah I was just gonna but the valve in the middle of the flex tubing

Ok another question what kind of sand should I use for the bottom of the sump where my live rock and stuff goes

 

[Grizz]

I wouldnt add any sand it makes it harder to remove the mulm that builds up in there.

 

[Droneshooter]

Mulm? What is that and ok so just rock and algae

 

[Grizz]

It's what i call the stuff that builds up in the sump it's easier to siphon it out with a bare bottom

 

[Droneshooter]

Ok I'll start with a bare bottom see if I like it can always add sand later
