Dan's new 120 build

So, I guess I should document the build of my 120 reef. It's been a loooooong time coming as I've been in the hobby 10 years and always wanted a big tank. I had a 10, a 20, a couple different 30s and now this. I've been collecting equipment for about a year and now the build is really underway. I will try to have a picture intense build since there's nothing worse than a thread with no pics.

The build so far...

120 Marineland tank with one overflow - standard 4' x 2' x 2'
The display tank will be in my new dining room so it's imperative that it is a.)quiet, b.)nice looking and c.) doesn't smell like Lake Ontario.

After much debate, I decided on locating the sump and equipment in a former laundry room that is about 5' x 6' and offers plenty of space for doing what I want. Because the plumbing was already there, I added a utility sink and relocated my RO unit. I built a plywood bench to put the return pump and sump on and it also gives me a little workspace.

Because the new fish room is separated from the DT by a hallway I had to run the plumbing down into the basement and back up, and since the sump is lower than the overflow it all works OK. One thing I am considering is lowering the sump position by about a foot to get more capacity out of the overflow. It seems to max out around 400 gph before it starts acting funny.

I made the stand myself - it's constructed of a 2x4 skeleton and has maple plywood and solid maple corners, trim, and top. In retrospect I should have just skipped the 2x4 part because it basically ended up being a piece of furniture. Oh well, it's a friekin' tank.

I still need to make the canopy, but it will match and contain 2 x 250 watt radium 20000K MHs powered by a bluewave7. I really like the radiums run with M80 ballasts. Nice crisp white with a bit of blue. I'm hoping to avoid actinics, but you never know.

Skimmer: Octo DNW200 recirc.

in tank flow: for now, two MJ 1200s with the algae free kits and magnets mounts.

Last spring I made my own DIY rock and it cured all summer. I'm pretty sure it's good to go considering it's been almost a year...:rolleyes:
I'll add a bunch of live rock to get it seeded and in a few weeks I'll hopefully be through the initial cycle.

Right now it's coming up to temp, the tank, sump, and skimmer are running and I'll be adding live rock soon.

That's all for now. More to come :)
 
awesome

awesome

4 x 2 x 2 120 = a great size for a reef aquarium.

It looks like you have a LOT of projects going on right now. Nice woodwork!
 
Man I really like the stand as well. I like the little lip around the bottom nice to have and adds a great look IMO but mine always seemed to get cluttered with stuff. Seems like the real trick will be to get whatever flooring you’re planning under it and the molding behind it.
 
Looks great. When making my stand I found out the same thing about the 2x4 frame, overkill. I finally got my canopy done but still haven't finished my doors and it has been two years:)

awesome ...looks great,question for you on the drain..Will the gravity drain have enough pressure to pump it back up into the sump??

I was thinking about going with a system like this,but then backed out and went through the wall lol..
 
Thanks all, it's going to be fun. The new flooring for the dining room isn't in the budget right now, and I'm not sure how I'm going to go under it but I'll figure something out.

For the overflow plumbing as long as the sump entrance is lower than the overflow it will work. It seems like I may need to lower the whole sump setup though, because right now I have about an 18" height difference. I'm thinking another foot lower would help. The blueline 40 is constricted to probably half of what it can do and I'd like to get a little more flow through the sump, say 600 gph.
 
So the tank is up to temp and the live rock just went in tonight. I've got 2-250 watt heaters on a blueline controller, seems to be working well. We'll see what the skimmer starts to pull in the morning. woo-hoo!
 
So, thanks to JamesRA I have all the rock I need and the cycle is underway. I have a temporary rack to put the lights on while I build the hood. The lighting is SE 250watt radiums on an M80 (HQI) ballast and I'm loving the color. It's nice white with a bluish tint that is perfect for my taste.

The reflectors are a DIY version of the lumenarc mini using sun tunnel material.

Gary, I think it's perfect. I may add some LED strips eventually just so I can do dusk/dawn, the blueish white is really what I was looking for. Kent recommended Radiums to me a while ago, I was skeptical at first, because I remember seeing really blue ones years back.

Making the second reflector right now.
 
Here's the tank at one month. The yellow tang is in a QT being treated while I wait for the ich to die off in the DT.
