I've been on RC for several years through the research and planning stages of each tank, but this will be my first build thread and am definitely looking forward to any and all feedback! I started a 55g tank as my first reef tank a little over 2 years ago. I would have to say it was definitely a learning experience. I didn't fully have a grasp on everything until about a year through everything. I had a few small zoa colonies, brain coral, and some easy to keep SPS coral. Unfortunately that tank crashed in the 4 day power outage we recently had here on the east coast, so here starts my first build thread. This tank is a standard 75g tank 48"x18"x20". Originally I was going to transfer everything from the 55g into the 75g, but I got lucky the crash happened before the transfer, because now I can start with an entirely fresh setup while not having to rush the process.

I've already gotten quite a bit done, I've just been putting off getting this thread started...I've got a lot of pictures to post and have never posted pics before on the forums, so this may be a little interesting at first but bear with me.

I got the stand used from another reefer, and refinished it with polyurethane the week before the power outage. It's only about 28" tall which is a little too short for my taste, but for the price it was not a bad deal.

Here is a list of the starting equipment I will be using on this the 75g, along with rock and sand info in the display tank and fuge:
- 48" NOVA Extreme Pro 6 x 54w T-5 lights (from my 55g tank)
- I'm not sure exactly how much rock I'm putting in the tank, but I know it's fine. It's somewhere between 60 - 80 pounds in the DT. I will post a picture of the dry aquascape and would like to hear some feedback!
- probably going with a 1" sand bed. I bought 60lbs of dry Aragamax sand from Drs Foster and Smith. It is definitely a finer grained sand. I previously had a courser sand in the 55g which was about 3" deep which I wasn't very pleased with. I decided to throw out that sand rather than try to re-use it. New sand has been rinsed several times. Hopefully this will be enough for the DT and fuge.
- CPR-CS100 overflow box since the tank is not drilled. Hopefully this thing will be nice and quiet. It is rated at 800gph.
- egg crate top to eliminate my previous carpet surfing problems. Hopefully this will not block out too much light from getting in the tank.
- 2 tunze 6045 powerheads. These are not the controllable pumps, but do have a nice wide flow. I previously had koralias and really prefer these.
- tunze 6206 wavebox
- the most important purchase I have made over the past month has been the Neptune Systems Apex Controller. I added on the PM2 module to have the conductivity probe along with the PH and temperature probes. I don't know enough about ORP to make it worthwhile for me to do that one yet.
- JBJ ATO which I will have hooked up to an aqua lifter pump
- 2 BRS 1.1 ml per minute perastaltic dosing pumps for ALK and CA from BRS 2 part recipes
- 29g aquarium which I baffled into 3 chambers for my sump and fuge area. First chamber is where I will have the filter sock(not sure how long or if I will use it) and the skimmer.
- skimmer is a Aqua C Remora Pro which I orginally used for on the 55g tank and worked pretty decently. May upgrade to another skimmer down the road depending on livestock.
- In the second chamber will be the refugium section. I will get into my questions for this in the post coming up directly relating to the fuge with a picture of it's space. I plan on doing a couple inch sand bed with a couple pieces of LR and a variety of macro algaes. I'm not sure if I will have snails or crabs or what in there yet.
- Third chamber will be my return which is a Mag 7 pump which I think is about 750gph. The return line is about 4ft long so it loses a little flow, but I'd like the fuge to be a little lower flow anyway.
- Lighting the fuge will be a home depot clip on light with a 27w ecosmart true color compact flourescent 5500k light. Hopefully this will do OK for the macro algaes.

I think this pretty much covers the first general over view of things...if I missed anything I'll just have to add it in.

So far I've accomplished:
- refinishing the stand with polyurethane
- giving the LR from the old tank a good vinegar rinse followed by a few RO/DI rinses and left out to dry for several days.
- rinsing new dry sand
- got the empty aquarium and sump setup, and made sure they all passed what my buddy has coined as the witch test (making sure they hold water)
- mounted all the aquacontroller pieces, dosing pumps, and situated everything within the stand (the sump/fuge is actually going to be outside the tank on the right side)
- I measured out a cardboard piece with tape and got an aquascape organized with my dry rock.

I'm going to make several posts with pictures of things so far....we will see how the picture posting goes
 
This is the aquarium and sump in it's spot in the basement by our bathroom on the left side.

This is my first photo post I am testing out. Let me know if you can't see it
 
Here are my pictures of the aquascaping. I would definitely like to hear your opinions!

Description starting from the left:
-Left mound(left side of arch) has a hollow area with openings to get in and hide. Hopefully this will not be a problem as water should be able to flow in and out easily
-Small arch on left side which tapers off along the sand bed towards right side of the aquarium behind the pillar
-Pillar in center creating sandy pathways between structures to create a little depth
-right side has a mound with shallow cave which should allow a few more hiding/shady spots in the aquarium for a variety of conditions.

Again, let me know what you think!
 
Here's the final post of what I've done so far


Everything mounted on the stand. Not far from moving rocks into the aquarium and getting this thing to the cycle stage!!

Nice equipment to start!

Why not drill the tank though? I started my first tank with a HOB Overflow... however I couldn't have been happier switching to drilled overflow. The peace of mind was worth the risk. It was also quieter to.
 
I just wanted to save on extra costs, and didn't want to drill it myself and making things more difficult for myself during the setup. I've actually already tested everything running with water and it's extremely quiet the way it is. I also designed the baffling to be low enough to allow space for when the back siphon happens during a poweroutage, since this was a major downfall of my last system since I also didn't have an ATO.
 
Everything looks good and well thought out. My only advice/input would be to maybe look at a mesh screen instead of the egg crate for a cover. The BRS web-site has a great instructional video on what you need and how to assemble the screen/s. Otherwise, looks like a great build and I will be following along.

I actually do have a BRS clear mesh screen top which I haven't assembled. I just watched the video but still can't see how to work around the HOB overflow I have because of the metal frame of the screen. Any ideas how I could do this with the BRS DIY screen?

And I figured with the egg crate I could just have 2 squares which are easily removable and I could easily cut a rectangle around the overflow.

You can do the same thing with the metal frame. I built a mesh screen for my Q/tank and had to cut around the AquaClear filter I use for this tank. You have to cut the frame in angles and use those corner pieces to connect each angle. Its easier than it sounds. Good luck.
 
Got the tank filled, rock in, and sand down. Finally operational!

Cycle begins tonight....here are some updated pictures. I couldn't perfectly replicate the left side of the tank and had to use a little more rock, but I think the scape is still right on point. It was nice to only make one scape during the whole process and know that was the winner immediately...

Everything seems to be panning out just right so far.

I will be cycling with Ammonia and Biozyme, as well as getting some sand from fellow reefers to seed the sand bed.
Tonight I will put 1/8 teaspoon of biozyme and 13-14ml of 10% Ace hardware ammonia hydroxide the tank and get this thing rollin.

Let me know what you think!
 
For this cycle I will be bumping the temp up to 85-88 and adding airstones to get the water nice and oxygenated. I've read a couple articles of guys cycling their tank in as little as two weeks using this method....we will see about that. Over the next couple days I will be stopping by several local reefer's places to grab some live sand to seed and maybe a rock or two.
 
Last night, I put in about 16ml of the ammonia but did not have a test on hand to test the ammonia level, only the calculator to base my dose. I said 95g tank volume. I got my ammonia and nitrite salifert test kits today and tested all the tank parameters.

Here's what I got between the IO salt mix and the ammonia dose:
SG:1.023 - 1.025 (used hydrometer not refractometer...waiting to calibrate refractometer before using it)
Alk:9.9 DKH
Ca:350
Mg:1170
NH4:right around 2ppm

I feel like there must have been a problem with the test. According to the calculator I should have been between 4-5ppm. Testing error maybe? Why is it so low?

I just seeded with live sand from marine scene but it was put in the tank like 15 minutes before I tested ammonia so it couldn't have taken any out of the water realistically.
