500gph might not be much once you calculate head loss. Head loss is the amount of pressure your pump will have when pushing water through pipe, fittings, in the upward direction, etc. This can cut down the actual flow by significant amounts. I would say you prob want at least 500gph AFTER head loss. One way to figure out what kind of flow you're looking to actually get is to try the RC head loss calculator.

I personally prefer the Quiet One series of pumps. They are relatively cheap, have low energy consumption, little heat transfer, and MOST of the time are very quiet. Compared to the MAG series, these are the best bang for the buck. I would look into either the QO 3000 or 4000. If you do a little searching online, you can find both for cheaper than the link below.

I too use a mag 9.5 in my sump....it is a quick way to get up and running....using the head loss calculator I have about 780 gallons an hour return....an external is better if you have room for it...I have a 75 gal RR with a 40 gal sump...it works fine for me.....Dave

I don't think I would want to run a mag externally...the whole o-ring and cover thing scares me...one of these days I would like to drill my sump and add an external.....I should have done it last year when I upgraded my sump...but I didn't have patience enough to wait...and settled with the mag....I think maybe for cruella, the mag would be best to get her up and running...but if she has the means and time I agree that an external is the best option.....
Mag2 on my CaRxn has seal problems. Even with a new cap and seal, its difficult to maintain leak-free.
I don't think cruella needs to deal with an external at the moment...remember, sounded like cruella was reluctant to go with a sump to begin with. Go with a quality internal (submerged) pump (sorry, no suggestions from me on which)...get your system running for "a while"...relax and enjoy!
Forgot: What do you intend to keep???

For a quality in-sump return pump I recommend using either a Rio Hyperflow model # 12HF or 14HF or an Eheim model #1260
Basing this on the fact that you probably have a 600 gph HOB overflow? Is wise to get a head loss calculation before choosing
Do not want to pump your sump dry, exceeding the flow of your overflow. Thats your biggest worry IMO
Thats my .02

ok my tank is coming reef ready. the holes are drilled. there is only going to be about 3 feet between the tank and the sump. I am making this easy. no bends and turns . Where would I put the external pump?? I am worried about heat, I don't want to cook my fish. in the summer my house is about 70. I have central air running at all time.
Theres always bends and turns. Will it be 1 or 2 overflows? Need more system info! ? If an external pump you will need to drill your sump. Easy if acrylic? Glass is another story.... Pump will sit next to the sump externally on your tank stand base.
Depending on tank size? At 70 deg's and having cetral air i don't see your tank cooking your fish. Reef is another story though. What kind of lights are you planning on using>? All important information that needs to be included before being able to assist you in anyway..

Cruella,
You shouldn't have to worry about heat if you have central air running in the summer. I also agree with Tony, you shouldn't worry about an external pump at this point in time. When you calculate your head loss, you will have at least one 90degree bend to calculate in. Do you happen to know the exact model of the tank? We can probably figure out how much flow your overflow can handle.
Michael, I have not had any problems with the QOs. Right now I have one 4000 and two 3000s. One of the 3000s is a little noisy, but it isn't a big deal. The other two are very quiet with only a slight hum.
I also think the Eheims are great pumps (have one myself), but they are definately more expensive. You're probably looking at double the cost for the equivelent flow of a QO or MAG.

ok I go the tank from toney at swamp bottom. it a reef ready ocean 75 tank. The holes and are on the bottom . As for lights I have a jebo t-5 lights. I know they are not good. I plan to upgrade soon. I can only spend so much at once. Also I do Not like cancer causing MH lights. plus they kill you electric bill. All I want in there are fish,mushrooms and zoos. I am not going to jump in and go crazy with coral yet.
Agree. Heat should not be a problem at this point. Best to keep things relatively simple. An in-sump pump would be best. For the Price $$ I would go with the Rio-Hyperflow. They are very quiet, reliable-will start back up after a power failure. They are $50 to $65 bucks. Easily adapted to PVC with barb adaptors.
I have used Hyperflow pumps as well as Eheim and Mag drives. I believe i have read the Quiet ones sometimes do not restart after a power failure?

Cancer causing???? Where te hell did you get that one from???? MH bulbs will not cause cancer by any means. The single ended bulbs are UV sealed and the HQI bulbs are used with a UV shield to protect the tank and you.
For what its worth, the T5 bulbs you use are the same as a tanning bed.......So, you still want to talk about cancer causing lights?
Chris
ROFLMAO!!!
Some bulbs can give off excessive UV-m fried some corals over the years- but they let you know imediatly.
Lots of pump recs here, but not enough discussion on what you want to keep>>>>>>>>
Maybe rio fixed probs with their pumps. Way too many people lost tanks from the pumps melting down.
My comments on quietone pumps are based on reliability, and again maybe this has been fixed.
for a 75g, shoot for a min 10x tank turn over (I have 1200 gph on my overflow itself). More pumps for the specific animals (anothe 3000 gph).
While you can change out the pump down the road, It is better to try to figure it out right from the start.
without that base starting point, the rest is uselesss/guesswork.
Don't use a damsel to cycle you tank....

If you are using a 20g for sump and don't want to drill it, then a mag pump would be a good choice. If you are getting live rock, then you can drop in some powerheads for the 3 week cure time and just not fill the tank alll the way. If you want to put sand in, then this is a good way not to mess up the main return pump.
