Ordering New 440/480 any advice?

[dr exum]

Looks like 2” drains -

I requested 10x turn over rate.

sump will be 180g - 6’x2’x2’

two echo tech l2 - 3000gph ea.

I’m 5th in line ?

I like the enlarged sump but those pumps just wont cut it imo. Youre gonna be running them both full power and still be nowhere near 10x.

Ahh, head pressure, flow restrictions n such....

It’ll be near though ya, 8-9x’s

Looks like 3100gph ea -

2” drains,

how will I calculate head pressure loss?

10%? It would still be 5580gph? = 9.3x’s per hour?

If he's willing to sell the pumps to you for $425, that's a good deal. $474.99 is the going price online.

for that pump not for a pump that size i bought every pump i needed for my tank for less then that. Return, algae scrubber, nitrate filter, UV sterilizer. and my return pump is over 5000 GPH and a 31 FT head height

Not arguing with you on pumps. I love Reeflo pumps. I searched for info on the Vectra L2. Comparing the L2 to a Hammerhead/Barracuda Gold hybrid pump might be comparing apples to oranges. The L2 has half the flow rate and half the wattage of the Reeflo pump. There are no comparisons to its wireless features. Reef keepers have always been years ahead of fresh water enthusiasts. They came up with Herbie and bean animal overflow plumbing. Always on the cutting edge of things, I can see that wireless control/monitoring of their pump and system from anywhere in the world would have great appeal to them. With the $$$$$$$$ they put into their systems and fish, and their need to monitor and control their systems from any where, this pump makes sense. I, however, am in the dark ages of fish keeping with no plans to advance out of it, so I'll stick with Reeflo pumps and a whole house generator in case of a power outage. I have a life outside of keeping my fish. When I'm away, my fish are on their own. There are two mentalities here: the Spare no expense, and the try to get the best deal. Those of us in the second group have difficulty understanding the other group. There are worse things people could be spending their money, time and energy on.

I found this flow chart for the vectra l2, which is not a very detailed one


First you have to figure out what your head height will be. With a tank and sump size youre talking, im gonna say its at least 5'. From the chart, you can expect this pump, on full power, in a perfect world, to push around 2300 gph. However, as Siddons11 and others have pointed out, you'll also be dealing with other limiting factors like plumbing and whatnot. For this reason this is why i always tell people to pack about twice as much "rated" pump than theyre planning to use. If you want to push 5000-6000 gph at 5' of head, than youre gonna want a pump or combo of pumps that can push 10000-12000 gph at 0'. This will not only ensure that you overcome head loss and plumbing restrictions, but also that your pumps are not operating at peak power, which can prevent the pumps from radiating excess heat to the water and less wear and tear/extend the lifespan of your pumps.

Like T Tj203 said, i think you have better options for the pumps. To answer your question, they will achieve 8-9x and they will work for your setup but they are expensive and i think they are a pricy, inadequate option long term.

Thanks for info, ya at 5’ (30” tank/30” stand )

8.3 x’s per hr.

3 then?

These are the recommendation of the builder, $500 here and there does add up, I’m generally inclined to use what ever materials are recommend by whom ever is doing the work.

thanks for input all!

Remember every 90° elbow you use is suppose to count as 1 foot so even if your return plumbing is 5 feet in height, if it takes 5 90° elbows to achieve that, it would be calculated as 10 feet
