Finally 240gal tank

[wattsupdoc]

Google Herbie overflow. You will find that system. Herbie is a member of a large SW mwessage board.
NO you dont need to drill another hole. If you take out the pipe then water will water fall ALLL the way down there to the bottom. I'm not saying go with the Herbie style, but I myself would if it were me. You just wont get the flow out of any kind of 1in standpipe. But you will with the Herbie style. You use the return hole for the backup, then run the return lines up over the top and into the tank. Again though, just using a 18000gph pump and throttling it back will be sufficient. The herbie though should be much quieter.

Let me ask you this if this don't work I'll go with Herbie method. If I am running my return over the top of my tank. That would leave all four holes in my overflow for drain. Could I use four standpipe at 600gph going to my sump? Then use a 2400gph return pump. I could still split it into multiple return lines when it to the top of the tank.

Thanks
Tony

If all 4 holes wll accomodate 1in pipe, then yes.

Nice job on the stand...I haven't read every inch of the thread and Doc is giving you great advice, let me throw in my 2 cents as I have a 240 FOWLR 8x2x2 with 2 overflows.
I would just go with a lesser return pump and plan on having 2 powerheads. For the record, I hate powerheads, but a necessary evil I think. You plan on having Tangs whom prefer tons of flow, it would be very difficult to have enough flow from just the returns. I have a Mag 18 powering both returns, with head loss that's about 1400 gph, I have 2 modded Maxijets adding roughly another 4,000 gallons per hour which is more than enough. I don't know how you would split 4 ways, but mine is split 2 ways.
I like Durso Standpipes, they have a great DIY site, and I am a plumbing idiot and it was still easy for me and cost under $20 for both.
I use an Aqua C EV 240 and like it, your sump would have more than enough room, just a thought.
My biggest regret was going with a 40 inch sump instead of 48 or more...I could post a pic of mine if you like.

Trying to get all your flow through your overflow is practically impossible. Power heads, or a closed loop is really a necessity.

Thanks kjr_trig, I would love to see pics of yours. We were planning to put a couple of powerheads in to increase the flow anyway. But we wanted as much flow as possible for the wattage. I figured it would be better to have a bigger return pump than four or five powerhead. I was thinking on bring a 1.5 or 2" return pipe up the back to the top in the center, then wyeing it to go 4' each way, 2' down put a tee and at the end put a 45. Question, would you reduce the pipe after the wye to 1"? What a the benefit a Durso standpipe verse mine (I don't know what it's called, pics above)?
Thanks,
Tony

I think with your design you'd get the flow you need for the 2400 gph pump. I know with a 1 inch bulkhead I had a 1000 gph actual flow returning with no problems. Just vent the tube. But I do think a 1800 gph pump system would be more than sufficient for your setup. I have a friend with a 75 below his 300. Using a mag 18.

Thanks, yeah we weren't trying to put it all, just as much as we could for as little watts as possible. We are going to use PH also. Plan on lots of flo for Tangs and it is a long (8') tank.

I understand but a mag 18 pulls more watts than a Reeflo snapper, so I'm getting more flow for less wattage. Plus, the snapper, I can have external to help keep heat down.

i'm not suggesting a mag 18, simply illustrating that you can do what you're trying to do without 3000 gph pump. More flow isn't always better through a sump.
Personally I'd dial down whatever the smaller reefflow pump is.

I see the snapper is the smallest reeflo pump at 2400gph.

 

[saltycrab]

The Reeflo Wahoo pumps out less GPH but with more pressure. The factory has a sale now also for $190 I think with the Baldor motor. This is a good deal.

 

[mcbdz]

Your right, I didn't see it before.

O.K. new question Snapper 2400gph at 98 watts dail down with no presure or Wahoo 1550 at 265watts with presure? which one do I need, totaly confused

 

[saltycrab]

With a pressure rated pump you can run eductors. Its really just preference.

 

[wattsupdoc]

The thing is, 2400 gph is ONLY 10x turnover so that's getting the minimum total flow from the return pump. I would recommend somewhere around 30x total turnover. My point of view on getting 10X through the sump fuge is really just about getting the detritus down there relatively quickly. Picking it up and moving to the fuge, skimmer or other filtration. You should rely on other means of flow to keep it in suspension as well as provide for your occupants. While I certainly recommend getting to that 10x amount, it definitely can be decreased or increased if the sump/ fuge is built correctly).
1800gph would certainly be a good flow through the sump/fuge. 1200 gph would be acceptable, but I cant recommend it. The thing is with a split design you would at 1200gph only be getting 600 gph through each compartment. This is only 2.5x. At 1800 gph you would be getting 3.7x and with 2400 5x. I would not try to exceed 2400 gph through the sump/fuge.
I run stockman standpipes myself. I like them well enough, but the Herbie style should be very quite. I plan to eventually change my 135 over to it.
The snapper would be my choice. For the return pump. If you don't want powerheads do a closed loop. Drill the 240 when you drill the 75. You will be SOOOO glad you did later on.
If you did powerheads I like the Koralis myself. I would do 4 K4's if it were me.They have the magnums now, but I don't have any experience with them, and the K4's really move some water. My Maxijet mods do move more, but the Koralias look much better.
Also, have you considered doing a rock/foam back drop for this tank? They look sooooo sweet.
I'll have you building on this for a year if you want to.

 

[kjr_trig]

Agree with Doc on the PH's again, however do their new Magnums (I think they are called), you could do 2 7s and be all set.
When I got my tank from Tenecor the "silencer" drains they had were terrible, Doc (may not remember) tried to help me silence them to no avail, I built the Durso and they are quiet as can be.
Here is a picture of my sump, just a little too small, the left side has the skimmer, the center has the Mag 18 return, and the Mag 2.5 powering the UV Sterilizer. The right has the chaeto (now out of control), 25 lbs of LR, and a 3 inch sand bed for a refugium.

 

[mcbdz]

I think that we decided to go with the snapper return pump, more bang for the wattage plus I could dial it down if I have to. We do plan on putting powerhead in the tank. We have Koralis PH in are 55 now and love them. Drilling the 240 scare me

I don't mine drilling the 75 if I break it, it's a lot eazier to replace than the 240. I see some people use Stockman standpipe others use Durso standpipe. I don't know what you call the ones I got (pics above), but what would yall recommend I use?

 

[wattsupdoc]

The ones you have aren't really a standpipe. They simply are guards to keep stuff out/Stockmans or Dursos it's preference. You got that sump built yet?

 

[mcbdz]

O.K. so do I go with Stockman or Durso? I haven't even started on the sump yet. Wife had me building a greenhouse/cold storage for her plants today. Maybe I can get started soon, before work find me. With my schedule I'm not home but 3 or 4 days a week. So it might take me a year to finish this build.
