3000Gallons thru sump - new pump plans

[krish]

Folks,

I am planning to purchase the sequence Reef Dart, the

3000+GPH saltwater pump offered by customaquatics.

The total cost including shipping is $193.

This pump runs with under 200Watts.

 

Here is the scoop.

The tank is a 120G.

I have a 29G sump that i run at say may be 1/3 volume,

currently running a velocity T4.

 

My choices are

a) Plumb the sequence to the sump - afraid that the

sump might be at high water levels and noisy water flow.

The plumbing to the tank is already 1.5" returns, but are

static( no water current devices hooked up)

 

Total flow would be

3000 + 400 = 3400 Gph

 

b) Plumb it in a closed loop.

 If i go this route, i would have the velocity T4 pushing

say 900Gph via the sump and the sequence doing 3000Gph.

 

The closed loop would terminate into 3 outlets.

2 - 1" seaswirls

1 - 1/2" tubing flowing to chiller and back to another

sea swirl. I might just leave this 1/2" static and

might drop the 1/2" seaswirl.

 

This would mean a total flow of

1000 + 3000 + 400 = 4400Gph

 

The 400 Gph is a hagen 802 that is on a backup UPS

 device that will switch over if the power goes out. This

one is running all the time.

 

what do folks think is the best option.

 

I have SPS that are doing good, but since they are growing,

they are begging for more flow.

 

Would also like to know if folks have used a small sump like

mine on a pump this size.?

 

tnx

The closed loop.  I have something similar on my 180 - but I use a Ampmaster 3000 and I have a drilled tank.  You could use two over the tank inlets to your pump, adn then return it exactly as you described.  I'll try to take some pics of my setup so you can see what I did, if you think it would help.  

 

As far as the sump return goes, If I did it again (and I might!) I would use a SCWD on my sump return.  Just put unions on the inputs and outputs so you can remove it for soaking or replacement.

What size is the overflow going into the sump.  I had a GRI pump 2100 gph with 3 2" bulkheads plumbed to the sump.  I have 1.5" return that t'd off to 4 returns into the tank.  The valve on the return side could only be opened halfway or the sump would run dry and or the water would go over the side of the tank due to high current.  Tank is a 150.  You will need a lot of water coming out of the tank to keep up with the pump return.
