Return Pump Recommendation Poll

[ensquire]

Looks like my Quiet One 4000 is going to be too small for a 90 Gallon tank.
There is a 30 gallon sump as well. 2 - 90 elbows , 1 - 45 elbow, 2 line manifold on a 1" return line. also a ball valve.
2 ft of horizontal and 4" of vertical.


Pumps I am looking at are:

#1 Sedra KSP-20000A
http://www.conceptaquatics.ca/index....p-1000a-8.html

#2 Water Blaster HY-7000W Pump
http://www.conceptaquatics.ca/index....0w-pump-1.html

#3 Lifegard Aquatics Quiet One 9000 Water Pumphttp://www.conceptaquatics.ca/index.php/lifegard-aquatics-quiet-one-1200-water-pump-6.html

or Your suggestions on #4

Waveline DC5000 would be my choice, go to www.rlss.ca to check it out. I believe or a least hope Mr. Dave @ concepts will be bringing some of these in as well as the larger size pump that is supposed to be coming out.

i run a 4000 on my 90 but i would go with a bit less for flow than what your planning your sump may not handle that much flow through it try an ehiem 3000 would be good for that tank. ideal flow is 5 to 7 times through sump total water volume. so if you have 90 blus say 10 in sump makes times 7.. you wouldwant a pump that could flow 700gph ish at 4 or 5' of head. keep in mind as well what your overflow ccan handle in terms of flow as well if your overflow can only handle 600 gph and your pushing 700 things could get wet.

HMMMMMMMMMM nice pump and DC to boot, controller would be awesome, but I wonder if it would be big enough with only 1320 GPH. There would be a fair bit of head loss and I think I should be looking for 10x turnover. Yes - No ???

Have you looked at this yet ?
Not all pumps are listed, but it's still useful

Do you run your 4000 wide open or throttled back ???
Using your formula, the 4000 would work on mine, as it calculates out at around 660, using RC calculator.

6-7x turnover is ideal. Keep in mind the purpose of the return pump is to feed the skimmer (in the sump), not to provide flow for the tank.

I have a Poseidon PS3 on my 90, and it is a good match. I'm replacing this tank with one that is about 100 gallons, and I will continue to use the PS3. They are great pumps and deadly silent. These pumps are now called Blueline Velocity T3. If you want an internal pump though, I would recommend the Eheim 1262 or the Eheim Compact 3000 (or maybe the 4000? I don't have time to do the math for you) if you want a cheaper model.
