Figured after about a year or so of very little posts, I figured I would make my first build thread.

I will say in advanced I like to type out every detail of everything that's happened, so this thread may be a little wordy.

This is my second attempt at a saltwater tank - my first attempt failing catastrophically when a tube worm of some sort built a tube in the pump chamber of my little AIO against the pump cord. Over time, and many vibrations later, had caused the tube to wear through the insulation of the cord and effectively electrocuted the tank. Came home to a dark tank and tripped breaker. Confused, I reset the breaker and found smoke coming from the pump chamber, and with the lights on, I realized everything was cooked. Except for my clownfish who miraculously survived. Tore everything down rehomed my clown, and gave up for a while. Now I'm back, due to Instagram constantly showing me pictures and reels of macro algae tanks. (Particularly tigahboys)

Tank is a 15x15 rimless cube, filtered with a sicce shark adv 800, and lighted with an ecotech radion xr15 g6.
Figured since there's no chamber and very little wires in the tank at the cost of aesthetics was worth the lowered risk of another fish and coral fry.

Initially used the Redsea ATO but it wound up being so finicky - preforming worse than the 40 dollar Amazon atos - the wack decision to use a siphon breaker rather than a plain old check valve, and the fact that finding replacement parts was rather hard irritated me so much that I went and bought a tunze osmolator nano 3. Night and day difference in ease of use.

Initially used dry Marco rock and caribsea ocean direct, but upon receiving a shipment of "seed rubble" maricultured Marcorock had me replacing almost all the dry rock due to the size of the live.

Tank was cycled with turbo start, dosed with ammonia, then seeded with copepods. Currently dosing microbacter purple m, to which I'm noticing is causing the water to be significantly clearer.

Macro algae:
Caulerpa sertularioidies
Caulerpa prolifera
Gracilaria sp. (Red ogo)
Laurencia iridescens
Purple fauchea (Fauchea sp.)
Rusty red ribbon (unknown sp.)
(Waiting on some halymenia stipitata)

Coral:
Pterogorgia anceps
Pterogorgia citrina
Random zoanthus that looked much better at the store than under my whites
Random rhodactis, also looked a lot better at the store than under whites

Livestock:
6x astrea snails
Lysmata amboinensis

Upon set up:

Dry rock swapped out for live rock - arrived same day as the macros and gorgonians:

The light shade is one I designed and 3d printed myself with a mylar liner glued in. Has a surprisingly noticeable (positive) effect on brightness and color in the tank.

And now the beginning stages of the ugly phase.
1000026343.jpg

Diatom out break ticked off my purple pterogorgia anceps, causing it to shed, with 3 of the tips dropping some tissue. Granted these tips were already rather damaged from shipping - but having kept sps and seeing them experience rtn, and then seeing the gorgonian peel and drop tissue is rather alarming. Luckily upon further research it seems that it will bounce back quickly enough.

The pterogorgia citrina closed up completely upon the initial outbreak.

Prompt water change and addition of more tsibe and apex pods seems to have helped the gorgs recover some, though the diatoms are still showing up at a rapid pace.

24 hrs later from the initial onset of diatoms:

That's it for now. Tanks only been up for about a month. More than likely I'll swap out the gracilaria ogo for hayi, or something more compact.

Looking for suggestions on fish. Thinking about a little school of green tiger gobies with some sort of swimmer, or shrimp - goby pairs, with some sort of swimmer. I've thought about a trio of pajama cardinals but the tank is a little small for them. Would love to find a tanakai wrasse or white banded wrasse but those seem rather hard to come across. Hesitant on getting clowns again due to the aggression.

Thanks for looking!

Looks great actually. The Gorgonian are awesome.
A Chalk Bass or Royal Gramma with a Citron Goby.
A Decorated Crab or a Fire Shrimp.
 
Apparently the universe is rather adamant about me not keeping a saltwater aquarium. Today I noticed the front glass panels seems to be pushing away from the rest of the tank, creating air bubbles between the panes.

Right as everything was coming together so nicely.... Last time I take advantage of a petco 50% off sale...

Tank is reborn!
Upgraded everything to a fluval visi white 60p (20.5 gallons) as it was the only tank in stock at the lfs that fit my table. As I was transferring everything over to this tank the cube began leaking at the upper corners so it seems I caught the problem just in time.

Replicated the original layout as closely as I could and added about a third of a bag of ocean direct sand, and an additional 5 lbs of maricultured Marcorock on the way. Whatever gaps I have after the live rock arrives will be filled in with my extra dry rock.

Gorgonians seem to be doing well, staying open the entire switch over until today, where the p. Citrina isn't opening up at all despite the tank being it's clearest today.

Added another whole bottle of apex pods from reef nutrition and a bag of tisbe pods to replenish whatever pods perished during the upgrade.

Had the lfs order me another radion so I could have more even coverage and potential future proofing in the event I upgrade yet again ;-)
 
It's been an interesting month since the last post.

I added an additional 8lbs of live rock and a piece of dry to even out the "scape". Got a nasty ostreopsis dino infestation, swapped out filters for a Sicce aqua filtra HOB, added my first fish (3 bangai cardinals and a midas blenny), caulerpa prolifera went sexual from the stress of being covered with dinos, then the following morning the HOB overflowed draining 70% of the tank.

Scape freshly after adding the new rock, and about a week before dinos really took hold. Testing out a cheap hygger pumpless uv lamp.

1000027028.jpg

Once the dinos took hold I began increasing no3 and po4 to 8 and .15 respectively, then removed the shroud of the UV lamp and placed it directly into the hob chamber for direct flow. For weeks there was seemingly no effect. If anything the dinos increased with the elevated nutrients. I lowered my lights to 50% schedule intensity, I began dosing all flavors of bacterial supplements; Seachem pristine, microbacter purple m, and microbelift special blend. Each dose I turned the UV off for 24 hours during which the dinos grew even more prominent. To make matters worse, due to the increased po4 levels cyano began to take hold in mats on top of all the dinos.

Day of the disaster. Came home to hearing water flowing like crazy and ran into the room to find this. Luckily my ato reservoir right next to the tank managed to catch a good portion of the water, and my cabinet stand caught almost all of the rest. Resulting in a relatively dry floor, and a now brined cabinet. The pterogorgia anceps was 95% exposed to air, so I was expecting it to die back completely. Miraculously only the top third of it dropped tissue, which it is already rapidly regrowing.

I'll be honest, coming home to this after weeks of battling dinos to seemingly no avail nearly made me quit again. It seemed as though there's something out there adamant against me keeping a reef tank.

Luckily an end to the dino fight was in sight.
I ordered some Tropic Marin Plus NP and BactoBalance as a last ditch effort and Plus NP worked like magic. I dosed 1ml in per day, and within the following days dinos began receding. The cyano seemingly disappeared or died off too.

3 days after starting plus np dosing. What's interesting to me is that plus np keeps my no3 and po4 levels at 0 and .04. I read that the organic compounds they use aren't detectable with typical hobbiest test kits, though I don't know the validity of that.
1000027481.jpg


Picture of the tank today. Most the dinos are gone, caulerpa is no longer looking horrible and starting to grow again, and the corals are opened up and happy! I've switched over to BactoBalance today as supposedly that's what you're supposed to do once plus np gets the no3 and po4 levels to where they need to be. Only unfortunate loss from the dinos was my once booming population of pods. Their numbers slowly dwindled the longer the dinos had control of my microbiome.

Added a nem this week - I got a killer deal for a Colorado sunburst to my delight. Once the nem gets larger I plan on getting a nice pair of occelaris from a local breeder who rears all his clowns in BTAs.

Current coral list:
Indo Colt coral from corals.com
Koji wada pink nepthea
Blue and orange micromussa lord from lfs
Purple and orange micromussa lord from lfs
Ora long tentacle white polyp toadstools from lfs
TSA pulsing Xenia
TSA acid bath zoa's (though they just look like magicians to me)
Pterogorgia citrina
Pterogorgia anceps

Light spectrum
During the day I run my radios at 10000k, with AB+ for on a 1.5 hr ramp up and down.

For flow, I have my nero 3 set to random all day with high variability between 15% and 60% power.

Dosing
On top of the Plus np or bactobalance, I am dosing 1.5 ml of cheatogro daily and 2 ml of ferrion every other day for the macro algae.

Filter media
I'm only running filter floss for clarity and a bag of carbon to prevent chemical warfare from the toadstools.

Speaking of macros, it seems the rock I received came with some fascinating species of macro.
I've got halimeda popping up on one rock, random ulva pieces cropping up, and a nice gathering of brown but highly iridescent blue macro. It's sort of putting my halymenia stipitata and laurencia iridescens to shame.

Unfortunately the rock also came with some Valonia, though given this is supposedly a macro dominant tank I guess all macros are welcome?

It also seems I got a little baby sea lettuce as a hitch hiker! It must have hatched from an egg on one of the live rock. It was released back into the tank shortly after I identified it.

And on a final note, yes, I do have a lid to prevent the blenny from jumping. Can't recommend kraken lids enough. Within 10 minutes of me placing an order on a Sunday they reached out to ensure I had all my measurements right.
