Re-building a 180...

Haven't really posted much on here before, so I thought I'd give it a whirl.. I should start with, "Hi, my name is Mandy, and I'm addicted to salt water fish tanks" :wave:

Last year I set up a 180 gallon display with a 90 gallon basement sump. After six months of horrific algae issues I've learned two VERY important things:

1. Never start a saltwater tank with city tap water
2. Never put more than 10 elbows in your return plumbing.

So, I've completely torn down the entire thing, and am starting over from scratch.

Here's a "Before" shot:

Sad, isn't it??


This tank was previously destined to be a home for my herd of H. erectus seahorses, but after much thought and consideration, I've decided that I just can't meet their flow requirements in a six foot tank, while keeping it clean at the same time. This 180 will now become a mixed reef tank, and the horses will be moved to my existing 65 gallon mixed reef: (After all the fish and bad corals come out)

The plan is to make my current 90 gallon a sump, and also add a standard 55 gallon in as the refugium. I originally wanted to make the 90 the refugium, but the new skimmer I purchased is too big for a 55 gallon tank :lolspin:

I had some fellow reefing friends come over and help me drill the 180 for a closed loop. I'll be using a Reef Octopus Water Blaster HY-10000w recirculation pump for that. This thing is a beast! It's got a computer chip in it to shut the pump down if it senses anything wrong, is 97% efficient, and is just pretty darn awesome. Will definitely solve my previous "not enough flow" issue...

I also upgraded the skimmer from a Eshopps PSK300 to the Super Reef Octopus 6000sss and also purchased the waste collector with auto shut off. Between the skimmer, and closed loop pump we'll call that a tax return:

The return pump from the basement is an Iwaki MD70RLT:

The tank it's self is an All-Glass reef ready standard 180 gallon tank with 2 overflows on the back panel. It has a 6x2x2' footprint. Each overflow is drilled for a 1" drain and 3/4" return. I'm going to be using 1.5" plumbing to help with flow, because even with a beast of a return pump, I hardly had any flow. I'll also be replacing elbows with flexible PVC. :thumbsup:

As far as lighting goes, I'm going to use my existing 72" Nove Extreme Pro until I can get it, and my old skimmer sold to fund LED's.

I've got lots of work to do, including a muriatic acid dip on the existing rock to rid it of all the nasty bound phosphates and such. I've already purchased new sand, and am going to be getting rid of the glass tops, and making mesh tops for it. Hopefully we can get this thing rolling in the next couple of weeks.
 
Thanks guys!

I did quite a bit of work on the tank yesterday.. Here are some more pics:

I repainted the background black, cleaned out the overflows, and put the standpipes and return pipes back in. I also made gutter guard covers for the overflows to keep snails and fish out. I've got a Pearly Jawfish that thinks my overflow is his own personal slide...

Full shot of the back panel, here you can see the closed loop holes:

I also got all of the rock dipped in the muriatic acid. I had about 300lbs or so of the Marco rocks, but it came out of that hair algae infested mess above.. It all looks so clean and shiny now, only I forgot to snap a pic of it...

Safety first, this stuff burns!

Also built the frames for the mesh top to replace the glass tops.. I still need to order the mesh from BRS... And I threw in a FTS so you can see what I'm working with.. Sorry it's so dark, tried to not get a glare, but with that much glass, it's a tad difficult..

Well it's been ages since I've updated this.. Things got pretty hectic for me. I found out that I'm getting laid off, and managed to flood my basement all in the same week. Things like that tend to delay your fish tank building a wee bit. I had just started getting things plumbed when the flood happend, but I think it turned out to be a good thing. Number one, because I hadn't filled the tank yet, so it was just a matter of cutting the plumbing apart, and number two it made me decide to paint the fish room floor with garage floor paint, rather than re carpeting it. So, I guess it turned out to be a blessing in disguise. I'm still jobless, but my current job doesn't end until September 12th. Never work for an airline...

Ok.. Updates:

After many, many design changes I ended up with the 180 gallon display that are plumbing into the basement. I used a standard 90 gallon as the refugium, and a 100 gallon stock tank for the sump. All the plumbing is 1.5", and instead of those nasty flow decreasing elbows, I invested in lots of flexible PVC.. Pretty neat stuff right thur.. :spin1:

I did manage to sell some of my old equipment and upgraded to some awesome LED's. I was originally going to make a hanging rack out of conduit, and then paint it but my "in" with a conduit builder fell through, so I bought a canopy to hang them in. Unfortunately All Glass doesn't make a pine canopy to match their pine stand, so I have an oak canopy. Any of you wood workers know of a good way to add a fake wood grain look to a pine stand?

More updates with pics to follow:
 
Refugium/sump stand:

I've had a lot of help building this with some of the guys from my local reef club. (Fox Valley Reef Club). My friend John gave me a full afternoon of his time, along with his wood building skills, and a stand design from an old thread here I believe. I'll post a pic of the design, unfortunately I don't have a link to the instructions. The stand is about 5ft tall, and you'll notice it's wide enough for a 125 gallon refugium which was the original plan, but turns out there's always a gimmick with free stuff, and it had a couple of blown seams. It's all good tho, as I've got plenty of room on either side of the 90 for a shelf...

Got it primed and painted it black, and then added a larger bottom to accommodate the 100 gallon sump's width.

To brace the stand we ended up having to attach a board to the joist in the ceiling and screw some runners from the stand up to the ceiling board. The floor was too uneven to be able push it all the way back against the wall, and they don't make cement nails long enough.
 
I had just started getting my fish room together, when the flood happened. Had to tear everything out, find a place to put it all, and paint the floor. Not the most fun I've had, but it wasn't horrible.

Spent an afternoon building the rock structures.. Not exactly sure on how many pounds it is, but I wanted to have an open design. I'm planning on having two or three larger fish, and so I want to give them as much swimming space as possible. I put all the extra rock I had in the sump, so I'm guessing there's about 400 or so lbs... I only used about 60 lbs of sand in the display, and about 45 in the refugium. I used the fiji pink aragonite. I love it's color and texture.

Lights! Bought these nifty LED's thru ReefGems.. Scored an awesome deal, and they're gorgeous. I have 3 fixtures, and they hang about 2 inches from the water's surface. I didn't have much room to work with in the canopy, short of cutting a hole it the top of it, and setting them on top but that would just defeat the purpose of hiding the canopy.

Each fixture has 112 LEDS with a 1:1 blue/white ratio.. It's 120 watts.
