IvanTheTerrible's 20 Long Build

First of all, I would like to start this thread by saying "Thank You" to everyone on Reef Central. I've been researching reef tanks for about a year and learned SO much from this forum. There are many very knowledgeable folks who are willing to share what they know, and plenty of folks like me who have a lot to learn. I've tried to learn from both groups. Without the new folks making mistakes and asking "dumb" questions, this forum would just be a bunch of experts sharing random thoughts with the hope that someone was listening. I don't know about you, but that's not very appealing to me. I love the diversity of opinion on this forum. It lets me consider many options and decide which is best for my situation. If I choose wrong, at least I went into it with a chance for success. Thank you all for making RC what it is.

OK, on to the tank. Initially I was planning to start with a large tank and skip the many upgrades that seem to come with small/medium sized setups. Unfortunately, I haven't found the winning Powerball ticket on the ground yet, so I decided to build a nano while saving for the bigger tank. I figure this will make a very nice quarantine and/or frag tank once the bigger tank project is underway. It took me a long time to decide on a size for this tank. Ultimately, I decided on a 20 long for several reasons.
  • First, it seemed to be the largest tank that had a reasonable chance of success with minimal equipment. Since I'm saving for a larger tank, I didn't want to spend a lot of money on a sump, return pump, etc. that would be overkill for a QT or frag tank. Yes, there are those with larger tanks that don't run a sump but 20 gallons seemed to be the most commonly recommended limit.
  • I also really liked the dimensions of the 20 long over other tanks like the 20 high. For some reason the length really appealed to me. Plus, most comments indicate that aquascaping is easier with a deeper tank rather than a taller tank.
  • I considered a cube, but everything I could find was an AIO. Nothing wrong with AIOs, I really like the way a lot of them look. There are some beautiful AIO tanks out there, but most people seem to upgrade one thing or another. I didn't want to buy something just to replace it with something else.

So, in early January I headed off to Petco and picked up a new tank during their $1/gallon sale. Looking at all of those AIO tanks, made me a little jealous of how clean they look without the heater and wires being visible. To hide mine, I decided to build a small corner overflow. Thanks to some folks in the DIY section, I was able to put together a small lexan overflow on my first try. It's not perfect but it's not the ugliest thing I've ever seen either. I also decided to paint the back of the tank black. I was pretty nervous since I had never painted a tank before. I was also worried because it was the middle of January and the temp has frequently been in the single digits, resulting in a pretty cool garage (probably lower 50s). I figured worst case I would be out $20 and have to start over, so I went for it. Surprisingly, it came out very nice. I left it in the garage for a couple of days. I would have left it longer, but it was on my wife's side of the garage :mad2:.

I placed a few orders, and soon had a 50 pound box of rocks from Reef Rocks on my porch.

Much to my surprise, the rocks didn't jump into the tank and arrange themselves into a wonderful looking aquascape and I struggled with them for quite a while. I was always amazed at how many people create threads looking for help with their aquascapes. I mean it sounds east. Just pile up rocks until you they look the way you want. I learned that it's much harder than it sounds. Ultimately, I'm happy with how it turned out and that's what really matter. I decided to silicone the rocks together since they were pretty unstable when stacked and I didn't want to start over trying to create a new look. I tried not to overdo it with the silicone knowing that I may need to take things apart of some point. Hopefully it doesn't come to that, but we'll see if that time comes. Rather than use eggcrate, I decided to use some acrylic sheet under the rocks. I think this will serve two purposes. First, if I ever need to remove a rock, I can easily lift an entire structure but leave the other in place. Also, since the bottom rocks are siliconed to the acrylic, I shouldn't have a problem with fish or inverts burrowing under the rock.

That's enough for tonight. Here's a shot of the final aquascape.

Once I had the rocks in place, it was time for substrate and some water (finally). Several years ago, I finished the basement in our house. When I did, I noticed that there was a floor drain very close to where the water supply enters the house. Unfortunately, I had to build a wall directly over the drain and left a small (2'x4') unfinished area around the water supply. There was no way to avoid it without an odd protrusion into the finished room. Lacking foresight, I decided not to notch the bottom plate over the drain before I put the drywall up. So now, it was time to pay for that stupidity. I crawled through my access panel into the unfinished area with my drill and the largest (and dullest) hole saw I own. After nearly losing a toe, I got the cut started. The dull blade grabbed several times, resulting in a lack of skin on my knuckles and some minor blood loss. Now that I had access to a drain, it was time to set up the RO/DI. I ordered the BRS 6 Stage Universal Plus model. It's overkill, but I'm OK with that. Installation was easy and I had the system up and running in no time.

On February 7th, I added water to the tank. I turned on the powerheads and the HOB filter. The initial sandstorm allowed me to see the flow and adjust the powerheads as necessary. The sandstorm didn't last too long and was pretty clear by the next morning. The next day, my ammonia was still at zero, which is not surprising since I used dry rock and sand. I stopped by Ace Hardware and picked up a bottle of ammonia. That night I added ammonia until I had a reading of ~2ppm. I was SO excited. I couldn't wait to get home from work each night and check my ammonia levels. My kids were not so enthusiastic. Since I'm slightly colorblind, I recruited them to help with the water tests. After the 2nd day, it was no longer fun for them and the recruitment turned into that special Father/Daughter kind of coercion - I threatened to take away their iPads.

On the 9th, I stopped by the LFS to look around and decided to buy a small piece of LR rubble. I figured it couldn't hurt and the small size would let me carefully search for hitchhikers. When I told the guy at the store I wanted a piece of rubble he just looked at me and asked "Are you serious?" I hadn't noticed previously, but apparently they had recently sold almost all of their LR. So this poor guy had to reach to the very bottom of the tank to get my piece of rubble. At the checkout he weighed my LR and chuckled. He'd just gone armpit deep into the tank to sell me a 32 cent piece of rubble. I just smiled and handed him my dollar.

By the 10th, I was starting to see nitrites and on the 18th, the ammonia finally hit zero. On the 22nd nitrites hit zero also and nitrates were at 15ppm, so I added some more ammonia. This time the 1/2 capful got me to 1.2ppm. I decided that was good enough. The next day, ammonia was down to 0.6 and nitrite shot up to three. Two days later (I was away and missed a day of testing) both were at zero. On March 1st, I ran every test I had. The results were as follows:
Alk: 5 dKH (Red Sea) or 4.536 (Hanna)
Calcium: 482 (Hanna)
Magnesium: 1380 (Salifert)
pH: 7.8 (Red Sea)
SG: 1.026 (Milwaukee refractometer)
Ammonia: 0 (Red Sea)
Nitrite: 0 (Red Sea)
Nitrate: 35 (Red sea)
Phosphate: 0 (Hanna)
So, I think it's cycled and I'm getting ready to do my first water change. I haven't had any of the algae blooms that are frequently noted. Is it possible I won't, or is that still to come?

I'll try to take a FTS and put it up tomorrow.
 
So, I did a 50% water change. Perhaps it's my imagination, but the water seems much clearer after the WC. I snapped a quick FTS. It's not the best picture and I didn't clean the glass beforehand but it works for now. Any comments or suggestions would be greatly appreciated.

The equipment I'm currently using is as follows:

Aquaclear AC70 HOB filter
Eheim Jager 75W heater - this is a little undersized but works for now
~20 lbs. of dry rock
CaribSea Aragonite sand
(2) Koralia Nano 425 powerheads
Tunze Osmolator Nano ATO

With all of the cold weather we've been having, the ATO is really getting a workout. I've been losing at least 1/2 gallon of water per day. It probably averages 3/4 gallon per day right now.

I've also noticed something growing on the LR rubble piece. Anyone have know what these are? I tried to search but couldn't find an answer.

No luck getting a better picture. My best guess was some type of hydroid. Regardless, I moved the rock to the quarantine tank. It's isolated there until I can positively identify it or the snails eat it.
