Return pump for basement

[brandon78]

OK so I am planning my basement sump build. Mt is a 93 cube 1st floor, sump will be a 40b in the basement. I think the distance from pump to return ovwrflow will be about 12 ft. With probabaly two elbows in it on the way up, then the 90 elbow where it empties out into the tank. I wanna keep it under $200 if possible. I've had my eye on the danners. That's what I have now is a danner 5. Would the 18 cut it? It's rated for 1800gph. Thanks in advance.

That's a lot of capital for a fairly little tank just so you can have a sump.

If an under-tank sump won't work, by any chance did you consider doing the tank sump-less? Tunze has some nice gear for that. Check out the Reefpack 500. It's $600, but comes with skimmer, media filter and ATO system that integrates with the media filter. Pretty sweet and a heck of a lot less bother and ongoing cost than a basement install.

Just a thought, I know it doesn't work for every case.

For a 90 gallon tank, you'd want something like 180 GPH (2x) up to around 360 GPH (4x).

We'll assume 12' of head pressure, 14' of plumbing total with three 90º elbows and one outlet and 360 GPH.

1.5" PVC would be well worth it to mostly-eliminate friction losses. With the 3/4" and 1" options, you're adding onto the head pressure.

You'd need a Mag 12 or 18, depending how accurate these assumptions are.

Optionally a Sicce Syncra 3.0 on the low end, up to a 5.0 on the high end would do it. Syncra Pro 5500's have the right flow as well and should be more quiet than just about any other option.

Panworld 100 is perfect. I ran my sump i the basement for my 93g cube lsst yr. I was using the psn world 100 pressure rated pump and it was more than enough. .you do t need a lot of turn over to the sump.

I would agree the Sicce Syncra 4-5 for that application as you will not hear it as it is in the basement.

 

[brandon78]

OK I will look into Sicce as well. I'm partial to danner because that's all ive used for the past 6 years in the hobby. I would consider that package but I already have the tank reef ready. It's been running with the sump in the stand for years but I'm tired of the noise and small work space haha. I appreciate the heads up on that though.

 

[brandon78]

This is going to be a overhaul of the system. I'm keeping the tank skimmer etc. But I'm building a new stand, got a new powerhead, upgrading sump and putting it in the basement. Also it will be nice if I ever upgrade tanks since all my equipment is overkill for this tank haha.

 

[mcarroll]

I would stick with Danner if you're a fan. I think if reliability is your #1 concern they may be the best choice anyway.

 

[brandon78]

OK so in your opinion which would be best between the 18 and 24? I believe my return pipe is 3/4.

 

[brandon78]

I keep getting mixed reviews about the noise of mag 12 and up. I looked at the sicce syncra but it's only 130 gph. Would that be enough with that much pvc, head loss? I think it's 3/4 pvc
