ok I'm sure you have read my beast tank thread. Tank is 90x30x30 for 350 gallons.

I'm building a sump for it and want to run the return pump externally. I found a pair of return pumps today - they are reflow darts but I don't think they have enough power.

What do you recommend. I don't want to blow my brains out on the purchase price but I don't want a POS either. I may also run reactors off it if it has the power.

I'm going to guess that with elbows etc it will likely need 20 ft of head. Thinking of 3-5 TTV per hour which is 1200-1600 gph.

I won't be setting it all up till next fall but will be piecing it all together for a winter project. Stand will be done this summer or by October.

Looking for big halide reflectors I think lol

Run your 2" pipe as far as possible before dropping to 1" to feed the tanks returns. Yes it will cost more. But you won't have as much friction loss in the larger pipe.

There is an iwaki for $100 on the dry goods board that would meet your requirements. I am looking for similar numbers for a similar sized system and have a blue line HD 70 which will yield similar results given that I will be dealing with lower head loss.

Not sure of your budget but I would try to pick based on energy consumption not purchase price, anything that runs 24/7 will give you your biggest cost savings in the long run.

I have a Mag 24 and it is a beast on power at 265 watts. Considering it runs 24 hrs a day that is a lot of power consumption. But it met my needs.

Mag 24 won't handle 20feet of head.

The power numbers may look big but in a high head/pressure application you don't get much more efficient than the iwaki/bluelines although a brushless DC high pressure pump would be nice to see....

Oh i am not saying he should get a Mag 24. I am just saying it is nice to be power conscious but sometimes you have to go with what works.

I have a jebao 12000 running on max and today was vacin sand thru 1/2 vac hose to basement just a little faster then pump could keep up. Total height is 13-15' but with 14 elbows I lose it all. Im going to look at ways to reduce the total run.

Oh yeah...totally agree and reliability is key too....

Reliability is one of the reasons I went with the MAG drive. I used to have a quiet one pump and it only lasted 8 months and just stopped working one day so I switched to the MAG. The MAG 24 is not quiet but it is reliable. As a backup pump I still have my original Laguna that I first got as a sump pump and it ran over 15 years no problem. I only once had to replace the impeller and that was only because it ran dry after my original 180 bottom cracked. :(

When I say 20 ft I think I'm high. The pump will be right below the tank. It's 90 inches long. I'm going to make a sump that's likely 5 or 5 1/2 feet long and 24" wide or a bit wider. That leaves me room for calcium reactor etc.

The stand will be about 40" tall so I can get my skimmer in and out. Lights will be in a hanging canopy.

I figure it will be a run of 6 ft to the top of the tank. A 6 ft run to one side. 2 to the other. Then 6 ft height with 4 to 8 elbows. To maybe only 14 ft including the elbows.

I'm running my skimmer on a mag 24 and it runs so hot! Im trying to get the pumps out of the sump.

I'd ideally like to be able to run reactors off the return as well. I found a dart for 100 bucks that will push 2300 gph @ 0 head. I think it will do around 1500at 10 ft

I'm thinking maybe a barracuda.

Have also read about Dolphins. There's way too much equipment available!

I still think your way high, your height is from the water line of your sump to the water line of your tank.
