So, I'm about 85% done with this build, and while I wait for the tank to cycle so I can aqua-scape it, I figured I might as well make a thread for it. I bought the tank and stand in late July and have been slowly piecing this thing together. I will try to explain how and why I did things in the manner I did. So, without further ado, let me introduce you to the tank.

Obviously, it has not been aqau-scaped yet, but I'm waiting for the BRS Pukani to cycle because we have some rocks from our 30G setup that we would like to include.

The obligitory cloudy tank shot

This picture actually is the backside of the 29G sump. I have the main drain T'd off to feed the refugium and the skimmer compartments, both have a gate valve to control flow since I am using the Herbie drain method. The reason the return section is in the middle is because I wanted to control the flow of un-skimmed water going to my refugium, I did not want the water from the 'fuge getting skimmed because I would rather have pods and other goodies from the 'fuge making their way to the display tank rather than my skimmer cup. (Note, I used permanent marker to help me place the baffles vertically. and I used small pieces of 3/4" PVC pipe to raise the center baffle in my bubble trap, I left them in place because it was easier, and it helps support the center baffle )

IMG_9816.jpg


My silicone job...well...sucks, next time I do something like this, I will definitely smooth out the joints because I ended up having leaks. Not a huge deal though because the water all ends up in the return pump section one way or another.

IMG_9818.jpg


Return plumbing. ( I ended up eliminating all that PVC on the return pump because it was causing the hose I had to crimp, and severely impacted the flow in my tank to the point where a tiny little 210GPH powerhead was filling up the return section faster than the Quiet One 2200 return pump was pumping water to the display tank)

IMG_9814.jpg


Drain plumbing.

IMG_9815.jpg


The return plumbing in place.

IMG_9823.jpg


A closeup of the display tank side of the return. I split the return outlet for more control over the flow, although I will probably end up using it to agitate the surface of the water and use power-heads to create flow in the tank.

IMG_9820.jpg


Here you can see how restricted the return hose was.

IMG_9826.jpg


And here it is after I removed the PVC. (you can also see the drain line for my fuge here, it's the 1/2" PVC pipe that the hose is ziptied to.)

IMG_9849.jpg


here is the skimmer section of the sump. I actually sized both the return pump, and the skimmer sections for larger of both just in case...it turns out if I hadn't made the skimmer section larger, my plumbing would have gotten in the way of my skimmer. So the lesson I learned here is, give yourself some room kids! If you don't you could get boned!

IMG_9824.jpg


As a last minute decision, I added this threaded union to my main drain as a just in case...turns out it was a lifesaver, I had to remove it about three times while jockeying the skimmer in place, shortening the vertical 'fuge line, and to get my return pump out so I could remove the PVC crap, had I just glued it in place like I was originally planning, I would have had to cut it out, then wait for a week till a new bulkhead and gate valve came in.

IMG_9854.jpg


You can see here that one byproduct of my adding the threaded union to the main drain, I had to remove the handle on my gate valve in order for the skimmer to sit properly in it's compartment. No problem though, I just put a hook up in my stand, and hung the handle with a ziptie so if I ever need to make an adjustment, I can easily get to it.

IMG_9829.jpg


Here is the 'fuge with it's light before I filled it with water, I also ended up shortening that drain pipe quite a bit.

IMG_9825.jpg


I wanted to place a large chunk of LR in my 'fuge and I wanted it to have good flow on all surfaces with no dead spots in current, so I built this little stand to lift the rock out of the water.

IMG_9846.jpg


And here it is in the 'fuge. I don't have a chunk of rock picked out for it yet, but I placed it right below the drain line so that water flowing from my display "washes" over it, also I put a tiny powerhead in the 'fuge pointing straight at the rock. There seems to be the perfect amount of flow overall in that fuge.

IMG_9875.jpg


Here is the power center. I have both the whites and actinics on separate timers, the 'fuge light and moonlight LEDs are on a dual outlet timer since they both have the same light cycle. Since I live in an apartment, I bought a LCDI (kinda like GFCI)power cable from Walmart and have both power-strips plugged into that.

IMG_9851.jpg


I am also planning a DIY auto topoff which uses gravity feed and a float valve. so far, I have purchased an H2O 2.5gallon jug with a spout on it from Walmart, I tapped the spout so it would accept a 1/4" water line adapter. (the threads are 1/8" - 27 pipe tap BTW), and I put it on a small shelf in my stand. I'm still waiting for the float valve to come in so I can complete this, but here is what I have so far.

IMG_9852.jpg


And now for the lifeblood of the system. The water supply! I bought a 100GPD RO/DI system a while back which used a connector that connects to a faucet, what a hassle. So, I "fixed" it, it is now a stationary system. I also made my own RO membrane flush kit while I was at it. Yes, I did drill a hole through the wall in my apartment.

IMG_9844.jpg


That's all I have for now. I have to wait for the tank to cycle before I can go any further at this point in time.

In the near future, I plan to make a hood for the tank, and a diy LED lighting system. I bought an Odyssea 48" PC quad T5 w/ moonlight fixture from a member on the forum with the intent of using it as a temporary solution till I get enough money to do the LED setup, also, I figured it would be nice to have a backup in case something happened to the LEDS.

Very nice and thoughtout!

On the over the tank return, did you drill a few small holes right below the tanks waterline so it'll break the siphon when the return pump is shut off?

ironman= triathlons?
 
Looks like a great job so far! It was good to put the union on the drain line - did you put one on the other drain pipe too? Not sure if your sump fits out through the cabinet door, but if you ever need to pull it out of there for any reason...

Nice work.
 
You really want that rock to be blasted in the fuge.:gay1: Lol. Looking good :beerchug:
I think about every rental place I have rented has a hole or two in the wall before I leave.

Yes I did.

My forum name is not quite so illustrious in nature...it's a high-school nickname.

The sump doesn't fit through any opening in that stand, the only way I could get it in was by removing the center support that sits horizontally under the display. I may put a threaded union on that 3/4" drain line though.
 
A BIG +1 on the unions. It is very nice to be able to take that stuff apart easily when needed.
 
I'd wrap something dark like electrical tape around any flex hose down by that fuge light to prevent algae from growing in the hose. JAT
 
thats a nice start any updates?

Yes, a soon as I get a chance to take a few pictures.

Yeah, I was planning on zip tying black trash bag plastic around it, but I haven't gotten a chance to. Now I do have some algae growing in there.
 
Looks like a great build and seems like you have put alot of great ideas together on it. Well planned out! :beerchug:

Yeah, I did a LOT of research on the different options and I LOVE the outcome. This tank has so much more life than the 30G setup I had before. In the two months this has had fish and LR in it, I have seen quite a bit of coreline growth as well as Scypha sponges. The tangs and lawnmower blenny have been seen picking at the rocks, which started out as BRS dryrock. In the 30G, I NEVER saw the lawnmower blenny pick at the LR which was live when I purchased it 8 months previous. Also the water perams are more stable, the flow is better, the rockwork is great, the skimmer is amazing. I'm just glad I decided to get serious with this setup, my fish love it, and so do I.

Do you have any more recent pics? And thanks for the detailed thread, it has really helped me get things together for my 75g build. :beerchug:

Also, where did you get all the plumbing parts? Bulkheads, ball valves, stuff like that. I couldn't find them at Menards, I didn't ask anyone so they may be there.

Sorry, I keep meaning to take pics of the rockwork and recent changes, but, I have a 3 year old, 1.5 year old, and a newborn, so just keeping up with cleaning the tank is tough enough, plus I am doing research for a diy LED fixture, diy aquarium controller, and a diy swabbie retrofit for my skimmer. I'll make threads for all those as well in the DIY forum and link them in the OP of this thread as well as my sig.

I'm glad this thread has been an asset for you, I did a ton of research, and figured the knowledge I gained in the process of this build would be a good starting point for others just starting out in the hobby, or doing a 75G. I'm no expert, but if you have any questions, feel free to PM me. I'll work on getting those pics up...I promise! :ac39:
 
Bummer, I can't edit my original posts to add more pics. :mad::mad_3:

Well, first off, as you can see here, my return hose is now wrapped in black garbage bag, which was ziptied in place. I also added a fan for cooling since my tank temp was consistently @84 deg, I re-calibrated the heater, and keep the stand doors open at night. the temp hovers around 78-79 deg now.

IMG_0833.jpg


Here is my refugium, complete with a blue damsel that ArstenA gave my oldest daughter.
IMG_0828.jpg


here's my auto topoff container in action ( well, almost, I need to fill it up again)
IMG_0835.jpg


And the 36W Coralife UV sterilizer, we bought this because we have two tangs. It seems to be rather effective, we had an ich breakout when we picked the tangs up, and it went away after a week, and hasn't returned.

IMG_0834.jpg


here is my DIY seaweed feeder

IMG_0818.jpg


Now, onto the rock-work! I really like how this turned out, the display has all 40 lbs of BRS Pukani eco-rock that I purchased. I set up the rocks in a sort of wave like structure, the left side "bows" out to surround the overflow, the right side "bows" in to form a lower flow cove area, which also provides open space for the fish to swim in. The rock-work itself is full of "caves" nooks and crannies.
Left side!
IMG_0822.jpg


The right side!
IMG_0848.jpg


And a better view of the "cove" area

IMG_0824.jpg


The fish LOVE this rock-work, especially the tangs and our lawnmower blenny.


Here are pics of my first corals compliments of ArstenA! locations are pending, they are still recovering from the transfer and peroxide dip.

Purple Digi that I super glued to a small chunk of LR, the one shard on the right doesn't look so hot, the other two on the left look decent from what I can tell, I plan on moving them higher up the rock-work to a higher flow/lit area

IMG_0817.jpg


GSP (green star polyp coral) once again compliments of ArstenA, It hasn't extended yet, but it's only been two days since I put it in the tank.
IMG_0843.jpg


And lastly, some unidentified zoa thingies also from ArstenA, they don't look so hot either, but again, it's only been two days.
IMG_0815.jpg


Current display tank inhabitants are.
various snails
2 red legged hermit crabs
1 emerald crab ( I think...either he molted, or he died, either way, I threw away the exoskelital form of an emerald crab the other day, didn't think about him molting till later so I didn't check to see if it was a molt or not, and haven't seen him since)
2 feather dusters (one is hidden from sight)
2 pencil sea urchins
2 skunk cleaner shrimp
1 blue hippo tang
1 yellow tang
1 lawn mower blenny
2 blue-green chromis
1 non-spawning pair of true percula clown fish

sump inhabitants
1 blue damsel (male) compliments of ArstenA
1 half eaten sand sifting starfish (darn lawnmower blenny)
a clump of small calcareous tubed feather dusters, compliments of mnpilot
various snails, sponges, cope-pods, and hermit crabs.

For flow, I have 2 800gph powerheads facing upwards at the glass on either end of the tank, the flow seems perfect from what I can tell. I started out with one 800gph and one 1200gph powerhead on each side with the same configuration, but the flow was too much for the lawnmower blenny in my tank, he couldn't swim so he stayed in one spot it the tank just barely staying upright.

One thing I wish I had done differently is not screw my return pipe to the stand, instead, I wish I would have bolted it to the stand so I can remove it without having to move the stand first. (obviously making sure the nut side was to the wall, because you want to be able to pull the bolt out.)
Hope you enjoyed the latest installment of pictures!

Order the bulkheads from Discovery aquatics, Jay should be able to get some in for a low price. The gates valves I bought off of Amazon, if you are using the Herbie method (like I did) you will need to use Gates valves. If you happen to need 1/2" PVC I have almost a full pipe that you can have.

dont pencil urchins eat corals? I had one eat the legs off a chocolate chip starfish, back in my early days.
 
p.s.
hopefully you have a grounding probe
