125 gallon build (and question) thread

Hey there everyone. Thought I'd post this up here because I have some spare time right now.

Starting out with a little background. I have been keeping freshwater fish for 2.5 - 3 years now, my biggest tank at one point being a 90g and the most tanks being about 10. Ever since coming across our local reefing forum about 1.5 years ago, I have wanted a saltwater tank but I never had the time or money to do it until fall 2007. I came across a good deal on a 33g tank with a stand that would perfectly fit a 10g sump as well as a CPR HOB overflow. From then on I began slowly gathering the pieces for this system. Because I had fairly little knowledge at the time, I started with all the newbie equipment (Seaclone skimmer, PC lighting, etc). Not long later, "stuff" happened and I ran out of motivation, money and time to finish the project.

Then, this past spring, a local reefer who was moving to Calgary, AB had to unload his nano aquarium so I got 70 lbs of LR, a 10g sump, a 10g nano (36x9x9), nice 36" 2x 39w T5 lighting and a bunch more stuff for a good deal. Once again, I ran out of time so set it up so that system sat dormant UNTIL (yes, again) another local reefer was giving away a custom, drilled 30" long 25 gallon nano. Because I wanted to go a little bigger than a 10g tank right from the start, I picked up this tank and built a nice black stand for it. That is currently my tank that has been set up since September 1, 2008 and STILL has no fish in it. Again, a time thing. My goal for this tank was to start out by doing everything as good as possible so I splurged and bought a Euro-reef RS-80 to go along with the internally drilled (not HOB) overflow and 10g sump. I am using the T5 lighting (again, good lighting with individual reflectors) and have a good return pump and about 60 lbs of live rock in this 35 gallon system.

Even before I had fish in the aquarium, I got bitten by the saltwater bug. One thing that really got me was the complexity (that's right, complexity) of a saltwater system verses a freshwater system that's simply heater, bubbler, HOB filter and any old light. Ask any of my friends and they'll tell you I'm really into the equipment side of things. The other thing that was really cool to see was all the life in a saltwater system even before you actually put life in! Seeing all the worms skittering around when I flicked on the light was so cool as well as the feather dusters randomly growing here, there and everywhere. I was hooked.

Just recently, I was thinking about it one day and it just clicked. I knew I had to go bigger. So I'd have to scrimp and save and bike to work. So be it. Looking online one day, I found a local 125g setup (originally FW, with stand, two big AC110s, FW T8 lights and a bunch of gravel and rocks for FW) for $600, a good deal up here. After gathering together all the money I could, then borrowing $20 here and there (and a little more than $20 from the ever sympathetic Grandma :lol: ) I forced a friend into coming with me to help move it. After getting it home safely and maneuvering it VERY carefully into the room where it would reside, I started deciding on equipment and the like.

I knew right off that Euro-reef was the way to go so I came on here and found a used RS-180. But here's the full system outline I chose.

125 gallon aquarium

* Rear Panel Drilled - two overflow boxes with two 1″ drains plus one emergency drain
* Drilled for three 1″ returns, reduces down to three 3/4″ Loc-Line adjustable outputs
* 72Ã"”18.5Ã"”22 (LxWxH) with 1/2″ thick glass

55 gallon custom sump/refugium
Euro-Reef RS-180 protein skimmer
Mag 12 or 18 return pump
2x 250w HQI - 15,000k
1x 400w Mogul - 15,000k
2x 48″ 54w T5HO Actinic (staggered)

I have since dug up a brand new 2x (2' or 3') T5 ballast I was going to use on a freshwater tank awhile back so I'll probably stick a couple of 2' T5 Actinics in there so I've got two full 6' strips.

So tonight I have spent drilling the aquarium. Pretty scary when you don't know for sure that it's not tempered! Luck was on my side, though, and it was a successful modification.

I GUESS I should get back to studying (haha) so more details tomorrow but I will leave you with a few pictures:

Thanks everyone!

Glass for the sump was cut this morning, just need to go pick it up, hopefully later today although I am sick so we'll see...
 
OK, sump glass was picked up yesterday evening, however I'm going to wait on that until I test fit the sump into the stand to ensure all is well. I also picked up some more supplies, here's what $100 worth of misc. stuff looks like. Yikes!

Meanwhile I've done a few things.

First thing, I leak tested the drain bulkheads. Only one leaked right off the bat but I pulled off all of them and put some silicone in between the inside of the glass and the gasket.

I'm hoping the silicone will also help where I chipped a little (note, that is not chipping you see, that is silicone, the chips are much smaller).

I also got the third return installed while I was siliconing them in.

After that, I decided to get the standpipes done. Started out with these parts:

I first cut the pieces with a hand saw then moved over to my bandsaw to shave them of and make them nice and smooth.

Here's the first prototype.

A then test fitted that into the aquarium.

I found out that it was a bit too short so I cut a longer piece.

Both are done and the same height as well as the emergency standpipe, a bit taller than the others.

Emergency standpipe on the left.

Everything dry fitted in the aquarium.

That's it for today, next step will be painting the back black!
 
No, it's just off for easier measurement of the overflow box sizes. I'd LOVE to leave it off but I'm pretty sure there'd be about a 125g mess within the first day. YIKES

Update tho, retested the bulkheads last night, they all hold water perfectly. No leaks!!

I'm sick again today and slept in until 1 PM so nothing got done today however painting the back is next, as well as removing supports and installing better ones so I can fit the sump in the stand. More on this later.

I'm also picking up my return pump tomorrow. Got a killer deal on one locally, $135 for a brand new Mag 24.
 
I can't keep myself away from this crazy project! Today I got the new braces installed. The old one acted as a shelf and if it had any structural value at all (it snapped right off, not very strong), it would have been keeping the stand from caving in or out from it's own weight. Anyway, I have a 55 gallon sump (48x13) so I had to remove that so I installed two strong 2x4s on either side of the sump.

I also got the drain plumbing done. Dollarama (local dollar store) has cheap hose clamps, I paid $2.20 for a total of 14 clamps.

Also picked up my Mag 24 today. YIKES is that thing powerful!



Overflow glass will be ordered tomorrow.

i dont really know alot of people who like these kind of pumps but i love them. just remember you have to use the right size pipe it calls for or it will not give you the max output, go on the mag site or look on the box it should tell ya. what i did with mine is branch off from the main and put 2 little fishe reactors and also feed a fuge bucket with cheato rolling in it. i try not use powerrheads if i dont have to. ball valves are alot cheaper than a powerhead and elec.
 
Mine seems kind of noisy to be a return pump -- is this normal or was it possibly rattling against the bucket? Yes, I'm using 1" plumbing right up to my return where, unfortunately because I'm using Loc-line, it has to decrease to 3/4".

But I got the tank pushed back against the wall (about 7" from the wall so I can run the plumbing. It looks great already! As you can probably see in the pictures, I painted both the back and the side. I did the seventh coat last night so now it's nice and black.
 
Your build is looking great. Are you gonna cover the inside plumbing up with a box? (im refering to your durso(i think) drains )
