Will this pump be strong enough?

I'm trying to figure out if the pump I have is good enough for my tank.

The tank is about 65 gallons with eshopps eclipse large overflow box (I got it second hand predrilled so I don't think i can change the pipe sizes) Sump is about 18 gallons. There is a icecape 2k gyre pump in the tank as well. I'm planning on only doing soft and a few LPS coral.


Vertical lift (sump → tank): 4.0 ft

Horizontal pipe (4 ft): ~0.4 ft

4 x 90° elbows: ~2.0 ft (0.5 ft each)

1 Tee fitting: ~0.5 ft

Total: ~7 ft

From the pump to the tee it is 2ft of 1 inch silicone tube and the rest is 1/2" pvc.

What would be an appropriate turnover? I hear 5x-10x and then I saw a BRS video saying something like 3x is fine as well.

If I understand correctly if I go for 5x turnover, the pump should deliver 325GPH at 7ft of head.

The pump I was looking at was the Jebao DXP 2500 DC pump where I couldn't find a chart for it just that it's 660GPH that goes up 9.8 ft according to their table.
With the head pressure would a DC pump rated for 660GPH be enough or should I go bigger?

3x turn over is plenty, imo, and what I run on all systems.
So you would need approximately 200gph through the system. That pump should work fine for your system. If worried it won't be enough then get the next size up and run it at a slower speed.

I’d go the next size up. For me id rather run the pump at a lower setting than be close to running it at close to max.

Ok sounds like that would be the best option. Next one up is rated for 925 GPH so I'll get that then. Thanks!
