Many moons ago I kept a FOWLER tank, and after 3 or 4 false starts over the years I'm finally getting my first reef tank up and running.

I don't see too many build threads with a price / cost breakdown and since I'm a spreadsheet nerd, I thought it'd be fun to track here as well. One thing to note on the cost is that I round every total to the next dollar. For example something that costs $10.12 rounds to $11, the same as $10.99 rounds to $11. I included a column for my cost vs the true cost. I received a number of these items for Christmas from my wife, parents, and family members; thus they were free to me. The big upgrades were the AI equipment instead of the Jebao Nero knockoff and the Kessel A80 I asked for.

If you want to read more tank musings:

I'm currently just using the included filter sock while the tank is cycling, and that's largely to catch particulate from the rock (rookie mistake not rinsing it). I'll transition to adding some filter fleece in the immediate short term, and then add the filter roller once I have some actual livestock / bioload in the tank.

I may continue to play with the aquascape (building the structures was fun / addicting!), but for now this is what I've settled on. If anyone has any suggestions I'm totally open to feedback. I included a picture of the rocks showing the separate pieces so I can move / adjust things as coral grow / things change.

There's no sand currently in the images but I do have the caribsea sand, which I purchased before finding out about Tampa Bay Saltwater. In spite of not having a tank for about 10 years, I've somewhat followed the hobby on Youtube, so when Ryan from Bulk Reef Supply started Serious Reefs I subscribed there. I'm very curious to give the TBS jar package a go. I don't think I'll actually use the rock in the display, just the sand, but I'll add what I can to the rear chamber to help the biofiltration / cycle. Depending on how far the sand they send goes I'll add the Carib Sea sand as the base layer. The TBS sand wont ship until the 15th of January so I've got a few weeks.

I'm still not 100% sure on what I'll be stocking in the tank in terms of coral or livestock. My initial plan for livestock is a Yellow Watchman Goby with a pistol shrimp and a possum wrasse / pink streaked wrasse. I'd like to add a Fire Shrimp in as well, but do wonder if that's pushing it. If anyone has any other small fish suggestions to go with a fire Shrimp instead of the goby pistol combo I'm all ears.

As far as coral go, I'll see what I can find locally, but am looking at the typical beginner stuff of zoas, mushrooms, and leathers. My shortlist of specifics currently includes a Toadstool, Red Xenia, Koji Wada Pink Nepthia, and a rock flower anemone or three.

Provided I can keep the easy stuff thriving for a bit, I'll give a few LPS a try. I also saw a purple elegance coral that was incredible so finding and keeping one of those is the long term goal. The only SPS I plan on trying at some point is a Monti Cap. I can't explain why, but it's always been my favorite coral, so I'll add a red or green one at some point too.

Great start!!
I like your plan so far!
Just know that Monti Caps can/will get BIG!!
If you are willing to prune often, they can be kept in a small tank.
If it were me, I would definitely add some sand. Live or not. With such a small volume, all the surface area for bio activity will be key to long term success.
Keep the updates coming!! We all love a good build thread!

I had a planted tank for a few years, and didn't mind the trimming. Monti Cap. Doesn't grow that fast does it?
just ordered same tank. Is that a Kraken lid? if so, did you do any additional cut outs?
It is! I didn't do any additional cutouts. There is a gap between the rear baffle and the lid that lets the wave maker cord escape without the lid sitting crooked. I've got two of their lids and would 100% recommend them.
 
I love that you provided a price break down. It is crazy how expensive nano setups are when you buy the correct equipment like you did.

Great choice going with TBS. Great company to work with

Yeah, I definitely didn't look for stuff on the cheap, but I do have a few purchases I'd have done over time instead of right at the start. The big ones being the ATO vessel. Initially I thought it was going to be visible so I wanted something that wasn't a jug, but turns out it fits in the stand, so I'd have gone with getting a simple water jug. ...and the lid was overkill, but I tried a DIY one on my freshwater tank, and it annoyed me enough that I felt like the value of the Kraken was worth it over the frustration, haha. I'd have also added the filter roller much later and just swapped out floss every few days, but Santa was generous this year!


In another update, I added a small layer of the Carib Sea sand, to just get it ready and clear the cloudiness from the tank early. Also, added Fritz fishless ammonia and Fritzenzyme9 to start the cycle as well. The TBS in theory should take care of the cycle, but I saw a naked mocha clown at the LFS that had a single white spot on one cheek. I love the naked clowns and hadn't seen a mocha in person before and the depth of the orange was really something; that one white spot on the cheek was a fun touch. I'm hoping it'll be at the LFS for a few more weeks, and I can grab it as soon as the TBS order is in.

Love the scape! And I also love those clowns as well!
 
Got the ATO up and running, and started the cycle. I am guessing I overdosed the Fritz fishless because the API kit is reading blue and not green.

Check out that cable management! ...🤮
PXL-20260107-132917764.jpg


Didn't want to put a bunch of effort into the cables until I know the tank is going to stay there long term. I might move it across the room...

Next immediate change outside of getting the TBS order, fish, and coral is definitely going to be replacing that Tunze ATO pump. That thing is LOUD!

9 days for the TBS shipment to arrive and counting!
 
has your ammonia test come down? atleast green?
It hasn't yet. Whole family got sick, so I hadn't done anything with the tank for 3 or 4 days. Yesterday I did a 5 gallon water change, and it's still registering blue. I had to wait for the RODI to make more water before I could do any further water changes.

I've now got 20 gallons of RODI I made yesterday, so I'll be doing water changes until it's down to ~2ppm. The TBS shipment is supposed to be here in a few days so deadline on getting things in order is fast approaching.
 
Got the ammonia down to about .5 ppm with another 5 gallon water change. TBS Jar Package arrived today and I got that in as well. Got a few sponges on the rock, but otherwise no hitchhikers that I'm aware of.

Going to do a full suite of testing tomorrow, along with playing with the scrap a bit. The biggest rock just got stacked in the back because I didn't have another place to go with it.

Rearranged the rocks just a touch and did a parameter check. Things are looking good so far. Local frag swap is tomorrow, so I'm excited to see what we can find.

Ammonia = .5
Nitrite = .25 - .5 (color was really hard to tell)
Nitrate = 0
PH = 7.8 - 8.0 (color was really hard to tell)
 
Went to the frag swap and picked up a bunch of stuff.

Got a couple of rock flower nems, a fungia which I was advised is "easy", and a bunch of small cheap fraggs, there wasn't a ton of leathers at the show that I saw.

Everything looks pretty angry, and the bigger rock flower keeps turning on its head (which is okay I guess from what I see online).

Hoping everything opens up / colors up soon. The Duncan and zoas I got haven't opened since I put them in the tank.

Also, the tank isn't that blue my camera auto corrected that way...

Whelp, everything was still looking rough yesterday, and worse today.

I was following the one watt per gallon rule using the AI Prime app showing 15 watts, so I didn't actually check with a watt meter, but thought maybe my lights were too high. Turned the lights down about 2 hours before lights out and this morning as they've come on everything looks worse / dead except for the cabbage coral.

Going to do another parameter check this evening, but I've clearly made a big mistake somewhere. The first one that is for sure a loss is the hairy mushroom of all things. It's almost melted off the frag plug... Fungia has lost almost all of it's color too. RFAs haven't moved, but also don't seem happy.

Parameter wise the only things that fell outside of a "normal" range were my temp at 76 degrees (adjusted that to 78 already), Magnesium reading off the charts at 1550+ on the Salifert test. I did it 3 times all with the same result, but it's possible I'm just borking the test. Phosphates were 0.0 on the Hanna checker.

Going to retest everything once I'm off work, but there is the slightest smell of the ocean coming off the tank, so I'd imagine everything is not okay.

At this point I'm guessing it'll all be a loss, but I'd at least like to pinpoint where I went wrong. Also should have gone with 1 or 3 pieces and see how they did before going whole hog...
 
After days of testing and everything being relatively normal / expected based on dead coral spiking ammonia and that fallout, I couldn't get ahold of what went wrong.

I wasn't super thrilled with the Salifert tests. IDK if I am being dumb or doing some step wrong, but I was consistently getting 380 calcium and 1500+ / off the chart magnesium.

I really really like the digital readout of the Hanna checkers, so I went ahead and ordered the Hanna Calcium, Magnesium, and temp / Salinity checker. Order arrived and I started with the temp / salinity checker.

Pretty sure I immediately found my issue. My refractometer was reading salinity at 1.026 / 1.027, but the Hanna checker was reading the salinity at 1.039. I calibrated both before using so so there's obviously a huge discrepancy. I'm leaning towards me mis-calibrating the refractometer and the salinity being the issue. This would also explain why a water change didn't seem to help / change anything.

This week I'm going to get the water changed and all parameters as a baseline and then let the tank "bake", and keep testing. I'm then going to take a water sample to my LFS before adding anything and will make sure my test results are inline before adding anything else.

Oddly, one of the cheap frags I picked up (I think it's a red blasto but hard to tell) is showing some green on it's face, so as everything else has melted away it seems unhappy, but alive. I'm also, not sure if leather coral will melt the same way the others did, but the leather is still whole (but white) as well.

Other issue I ran into a few nights ago was that all the detritus / sand gunk clogged the filter sock. This caused super low flow / a backup so the return chamber of the AIO was emptying, due to evaporation, faster than the water was flowing. This caused the ATO to keep dumping water into the chamber while slowly raising the water level of the tank. I luckily caught it before it overflowed but I had about 1.5 gallons of water in the ATO definitely not that much room in the tank.

Absolute bummer of a loss, and the growing pains are frustrating, but lessons have been learned and progress as been made albeit not the way I'd hoped.

A few random notes / thoughts.
  • The sticky thermometer said it could be moved on the package. I tried to move it and it immediately separated / was destroyed. Should have gone with the little suction cup one in the first place.
  • The new Hanna checkers came with reagent refills for free with purchase so that'll save me $61 down the road.
  • I'm now seeing diatoms on the sand. I was hoping the TBS order would stave off diatoms, but given the tank errors already I'm just happy to know that there are signs of life taking hold / things are progressing.
  • After looking at the tank for about a month now, I really wish I'd gone with more TBS rock / purple rock. I really enjoyed messing around and building out aquascape pieces with the Marco rock, but the white color is a touch more annoying than I thought it would be.
  • I'm only 5' 7". It's really tough to work on the back of the tank without a step stool...
  • The total cost has been updated in the first post.



 
I've largely let things sit since my last update. Cleaned out all of the coral and the rear chambers and have been coasting for a time. The diatoms aren't completely gone, but as soon as I cleared out the coral and anemone gunk it was noticeably clearing up about 12 hours later. As it stands now, it's not completely gone, but not a huge nuisance by any means.

Current parameters as of last night are:

Salinity = 1.041
Ammonia = 0
PH = 8
dKH = 9.9
Nitrate = 29.9
Phosphate = .60
Calcium = 573
Magnesium = 1800

So things are out of whack, but that's to be expected with the high salinity and all the decaying matter. Will mix up a totally new batch of saltwater and do a 50% water change and then retest.

Looking back one big red flag was, the Magnesium not reading correctly. I thought I was doing the test wrong, but turns out it was just that high due to the salinity issues...

With the ammonia being down to 0 I'm going to say that the cycle / TBS sand and rock did it's job for sure at least as there was a lot of waste to spike the ammonia. Going out of town for a week coming up so provided things smooth out I should have a fish and or coral in there late this month or early next.
 
After a 3 gallon water change and letting things settle my parameters are now at...

Salinity = 1.037
Ammonia = 0
PH = 8
dKH = 9.0
Nitrate = 9.2
Phosphate = .43

Didn't bother with CA or Mg since those aren't really a concern at this point. I expected a bigger salinity swing with the water change, but it is what it is. I'm going to do another water change with RODI a gallon at a time until I get down to 1.026. Phosphates are really high so I might add Phosphate RX, but going through all the water changes / other parameters first.

On track to add a fish or invert or both soon!
