Project 180, a peninsula room divider LOG

Howdy all!!!

I've loved the large tank forum for as long as I've been an RC member. I'm in the early stages of setting up a 180 as a peninsula room divider. I welcome all advice (and encouragement :D )

Background
Having had a Saltwater Reef for a little over two years I've become totally hooked on this hobby. I was very disheartened when the 120, which was a living piece of artwork in our dining room, sprung a leak and had to be taken down. I considered getting out of the hobby but my loving wife convinced me that this was a minor bump in the road, nothing more. So it was decision time. I had a couple options. One of the quickest solutions was to purchase a new 120 gallon tank and simply replace the old tank and get back to business. Another option was to attempt to repair the current tank. While logic stated that both of these were quick and cost effective, the desire for bigger, better and different said otherwise. It was decided that a new tank would be setup as a room divider, between the family room and the kitchen. At that point I was on the hunt for a 6 foot tank. Having loved the 2 foot of depth to work with, I knew I needed to get at least a 180 gallon setup.

"Project 180" is a sequel to my previous "Project 120" tank upgrade. Last time I moved from a 55 to a 120. This time I'm moving from a 120 Gallon (4'x2'x2') tank to a 180 (6'x2'x2'). This change is happening due to the fact that the 120 started to leak in January of 2007 and was taken down. At that time all fish and corals were relocated to a 300 gallon horse troth, located in the laundry room. All occupants have been living in the troth (aka "the tub") for the past 5 or so months.

Project 120 Tank Setup

~ Tank - 120 gallon AGA. Originally undrilled, two 6" x 6" x 16" Weir style overflow boxes were added.
~ Lighting - 2x250 MH pendant with 2x110 VHO, dual fans and moonlights.
~ Circulation: Sequence Dart on a Closed Loop with zero head loss.
~ Sump: Home made Acrylic tank (Thanks Melev for the great instructions) about 40 gallons, sits under the stand
~ Heat: 2x250 Watt heaters in the Sump
~ Return Pump: In Sump Mag 12

Constraints for the new build
~ The new tank is 6' wide by 2' tall by 2' deep and again is an undrilled all glass tank. The sides are not tempered. The tank will be setup as a peninsula, so one of the short sides will be drilled for a close loop drain and a Weir style overflow box will be installed. The tank will be viewable on the two long sides and through one short side.
~ The tank will be located in the Family room, which is about a 6" step down from the kitchen. For this reason, the stand height will be about 36 inches to accommodate viewing from both rooms.
~ Sump location still to be determined (under the stand or in the basement). If under the stand, the stand might need to be a little bigger (wider) to accommodate the dimension of the Sump.
~ It will be necessary to reinforce the floor under the tank as the tank will be oriented parallel to the floor joists.
~ Two dedicated 20A circuits will be installed to support the tank and all equipment.
~ I love Deep Sand Beds, so I will have one in this tank as well.

Equipment to Reuse
~ Skimmer (ASM G2 with recirc and gate valve mod)
~ DIY Auto Top off
~ Neilson Kalk reactor
~ Heater (currently have one of the 250watt heaters, one broke)
~ Sump if it will fix into the new stand (or as basement sump)
~ Sequence Dart for tank circulation (closed Loop)
~ OM 4-way (closed Loop)
~ Mag 12 for Sump return if the sump is under the stand.

Lighting
My 4 foot hanging pendant is not going to work on a 6 foot tank. A local reefer was getting out of the hobby and breaking down her 125 gallon 6 foot tank. So I picked up a 3x250 HQI MH pendant with 2x140 VHO, dual fans and moonlights. All lighting is in excellent condition.

Progress Thus far
Got the new tank home

I've since decided to move the closed loop drain down slightly so that I can add two more bulkheads for closed loop returns from the OM 4-way. The other two returns will be routed over the top of the tank and output on the opposite side.

Immediate next steps:
~ Bulkheads and misc plumbing was already ordered (Savko)
~ Order glass to make the overflow box
~ Decided on basement or under stand Sump
~ Finish drilling the holes (2 done, 3 to go)
~ Finalize the stand design
~ Order

Only a Mag 12 for the return? Love the peninsula setup.

I got it new for $49.99 when I was first setting up the 120. Gota love Internet mis-marks.

I like lower flow through the sump, so it worked great. Actually it was a little much, so I had to divert some of the flow back into the sump. Also, being in the North East, we need to heat our tanks more than cool them, so a submerged pump helps a lot in the winter.
 
edwinn - Me too :D

golfschosen1 - Tanks!!

Here is "the Tub" this was taken the weekend of the leak so it's still very messy. Now it's neat and very workable.

this is going to look nice i am building the same thing a 180 i have stand tank pumps and all all i need is the tank to be built i will follow your thread to see how it comes out.
 
Chris looking good.
I to am working on a tank viewable from three sides. Doing a closed loop with a oceans motions 4 way eight holes drilled in the bottom with four returns 2 at each end.. Do you have a picture of the peninsula for rock scapeing?
I was looking at a two seperate reef setup with a large peice of flat rock to bridge the two together.
will be watching your post as it moves along.

savethreef - Welcome aboard!! Please provide a link to your build thread.

Barky - So far I haven't put a lot of thought into the aquascaping. I have a decent amount of LR in "the tub" and if needed will purchase a couple large pieces. I will likly try to have a couple islands with things a little more open in the middle. Time will tell.

i would definitely use the basement sump but you'll have to get a bigger return
I've got an extra Sequence Dart, so the pump is not an issue.

My reservation is making the hole in the floor, or in this case the step between the two floors. Going through a wall is not an option (covered in paneling).

I know we are moving in about 5 years so I don't want to "trash" the place just to have a basement sump. The other issue is, just below the tank's location is my work bench. I have no idea where to move that to, so that's problem #2. But I haven't ruled it out yet, hence the lack of progress on the stand.
 
wow looks like we will be going through the same ordeal.i just baught a 180 as well.i am going to be re using my g2 skimmer also.where did you purchase the pump for it to do the recirculation mod.good luck with the build.

edwinn- unfortunately I lost my foxface, a few other fish and several corals when I had an accidental Kalk overdose due to human error. It was a beautiful fish, model citizen.

jgs107 - When the G2 was setup on the 120 I used the sedra pump for the re-circ. The G2 was directly fed from one of the tank overflows. Now that it's in "the tub" I am using a Mag 5 to feed water, still using the Sedra for recirc. Seems to work well.
 
Made a little progress tonight and finally made a big decision.

First the progress:

Drilled the following holes:
~ Two holes for the 1.5" bulkheads for the dual overflows.
~ Two holes for the 1.5" near side Closed Loop Return
~ One 2" hole for the Closed Loop intake
The blue tape outlines the overflow box.

Big Decision
Talked to the wife and we decided that a Basement Sump would be the best option. First I need to move a shelving unit, and then find a new home for some basement "stuff". After that I will build a mock wall with a heavy duty shelf to hold a refugium tank (30 gal breeder) and the Sump.
 
I would definitely do a basement sump. You've already got the stock tank and the return pump. I would plumb some of the overflow into the G2 as a direct feed.I would also run the return pump off the drain thats built into the stock tank.

The couple 2 inch holes in the floor are very easy to hide. The fact that you can do a W/C and not make a mess in a lived in room is a big bonus.

P.S. I speak from experience... i've been there, have had a basement sump for over a year and wont go back.
 
Another thought.

Plumb the 'fuge off the return pump. I t'd mine off my drain line, but it leaves too much crud in my refugium. Let the skimmer get the rawest water first. I am going to re-plumb mine when I get a chance.
 
yeah also since you are doing a basement sump now you are not restricted to the volume size and have to worry about the weight on the floor heck use the the tub you have ur stuff in now as a sump :D your water will be really stable but imagine your WC.

Looks good so far. Are you going to paint the overflow side? check out this link. maybe you can use something he did. Its also a glass tank he show step by step from the stand build to the end. http://thereeftank.com/forums/showthread.php?t=37963
