UNS 120U Build

One of the very first things I've always wanted to do when I bought a home is getting a big tank. My largest tank so far was a 60 starfire glass reef ready cube. Having lived in apartments most of my adult life, I've always been limited to smaller sized tanks. I bought my first home back in July last year and took down my last reef tank. I had 3 reefs going for about 10 years with only one left up and running until the move last year. My last foray into planted tanks ended in 2012 or so and it was always something I wanted to keep going but couldn't due to lack of space.

I really hemmed and hawed over the decision for this tank. I initially was set on a standard 125 gallon. I began planning the build and created a spreadsheet with all of the equipment and accessories I'd need, and then I saw a 125 in person at Petsmart when I went to get some dog food for my pup. The length was great, but the tank just seemed really long and narrow which limited my options as far as scanning.

I saw the UNS 120U's dimensions and a few YouTube videos to get a sense of what the tank looked like, but I wasn't totally in love with it being only 48" long. I think an ideal tank size is 60X24X24 but there aren't many options out there. I did find one like that from a company SC Aquariums. Pretty nice tank with Starfire glass and an overflow. One of the main reasons I didn't go this route, which would have been less expensive than the UNS tank was that it had an overflow. The overflow opens up the possibility that a year from now I tear down the planted tank and set up another reef tank.

While I loved my reef tanks, they were just obscenely expensive. It was a huge toilet that I flushed money down. You can have a plant melt on you in a planted tank and you can just buy another. But if you buy a $120 acropora colony and it dies on you, that stings a lot more lol.

Anyhow I settled on the UNS. After bring the tank into my basement and waking up this morning to back pain, in hindsight I maybe should have gone with acrylic lol. The back pain will go aways in a couple days though.

This will be a slow build since the tank wasn't inexpensive and the equipment isn't inexpensive either. In the past I'd get inpatient and charge everything on my credit card, but you wind up paying way more for your purchases if you're not paying the balance off right away. So I'll take my time and acquire the equipment a piece at a time until I have everything. The one thing I will do is pick up any hardscape that catches my eye as I stop by all my local shops.

The first project is to build a stand. I'll reserve post #2 for the stand build.

Tank: UNS 120U
Stand: Custom build
Filtration: GLA 15L Infinite Nature Filter. Oase 850 Biomaster Thermo. Stainless lily pipes, one set with build in surface skimmer to be used with the Oase, the second set is without surface skimmer to be used on the GLA
Lighting: Twinstar 1200SP
Heating: Heater included with Oase controlled by Inkbird
UV: Decided against this but it can always be added on later. I'll account for adding one on in the way I plumb the return if I change my mind down the road.
CO2: GLA Pro DS 1 Dual Stage regulator with two 10 lbs tanks along with a NilocG Advanced reactor.
Substrate: Pool filter sand
Hardscape: Two xl pieces of spider wood. About 90 lbs of dragon stone.

I'm 100% open to feedback, ideas, or alterations I should make to my plans.

This week I'll begin acquiring lumber and paints/stains and hardware for the stand.

My plans on stocking are up in the air. There are a whole bunch of different stocking plans I have, but I really need to settle on one. Back in the day I would buy 2 of each fish until I realized it seemed like I was stocking Noah's Ark lol. This tank will have fewer different species and more schools of fish.

I'll get a pic of the tank once the stand is built and it's sitting on it. I'll also do the leak test when I get the tank on the stand. I may as well do that sooner rather than later.

I did want to thank everyone who has provided help thus far. There are so many things I hadn't considered that were a HUGE help so I appreciate it greatly!

I didn't have a chance on Saturday to go to the LFS, or remove the four large rocks in the back of the tank because I had company over. I more or less just did a standard water change and pre filter cleaning on the Oase while entertaining guests.

The potassium test kit arrived Saturday and I was very tempted to run a test but figured I'd wait until Wednesday night when I'll run nitrate, phosphate, and potassium at the same time.

This coming Saturday I'll be pulling the four rocks and doing some trimming and replanting. The one plant I'm not sure where to move is the microsorum trident which is in between the spider wood on the left, and the large rocks I'm going to remove. I'll need to figure out a spot for it.

Aside from that, the same CO2 tank is still running lol. That's probably the one thing about this tank that is blowing my mind. I would have thought that I'd have had at least two tank swaps by now, but the gauge still hasn't moved. I might pop into the LFS tomorrow and get an order in for a few bunches of stem plants, or at least see if he can get them. Alternatively I might just get an order in online so that I don't need to wait.
do PH as much as your fish need air lol
