Hello ... first post here!
just got my "first" reef tank ... 35 years after my last tank (75g fish only). my how things have changed. I have been doing a ton of research (this is a great site obviously) which has been very helpful, but also honestly kind of overwhelming and sometimes confusing.

My goal is to start back easy with an AIO, small tank to see how it goes and determine if I am ready to dive in to something bigger (probably 120-150). I am not really planning to do much of a "reef" ... perhaps some easy corals for fun, but not anything too delicate or difficult. I am primarily interested in the fish, and having a relatively easy maintenance regime.

I got a Maxspect Dice AIO 12 gallon. See pic. Great deal on sale for this complete tank with cabinet and nice light. has filter sock, bioballs ... we'll see if I need more filtration later
5lb live rock and 5lb dry rock from LFS - see pic
wet sand in a bag (alive I assume?)
salt water from LFS
set up June 1

LFS also suggested adding the Turbo start 900, so I did. but they also still said to go through the whole cycle and add some fish food and monitor. So I did that.

I was testing using strips from aquarium coop because I wanted easy and I read that ammonia and nitrites and trates would spike and show up very easily on this test.
Nothing every showed any spike at all. everytime they were all at the lowest reading.

Finally got an API master kit yesterday ... yes I know people have said their tests suck but again folks said for these basic tests and cycling, the API should be good enough to see the spikes. I tested yesterday and from what I can see it looks like all of these levels were at the lowest. is the ph low?

I have also noticed this lovely little brown / greenish stuff growing on the sand. started after a few days but has really picked up lately.

In my research I stumbled upon things like this -

and this got me to questioning if my tank is essentially already cycled because of the live rock and turbo 900? (and then to wonder why the LFS told me to go through the whole cycle if this turbo stuff cycles it quickly)
and is that brown stuff bad? It looks like it might be something called diatom ... is that bad? should I remove or jsut let it run its course?

I am not in a rush to add fish ... I can be patient and had planned on it. however, I dont want to sit here and watch the tank and measure more 0s and watch this stuff grow for no reason if I dont have to. If I can start adding fish or CUCs or something I would like to. Ultimate plan for this is like 2 clowns and a compatible fish like goby or something. then if things go well add some "easy" corals. Then fingers crossed eventually do the larger tank

Thanks so much in advance!

You're still showing Ammonia in the water (at least thats how the test looks to me)... or have i gone color blind?

The live rock alone was sufficient. The Turbostart was not necessary, but it works as advertised and didn't hurt anything other than the wallet.

.25 ammonia misread on the API test is very common.

I'd add a fish.

Welcome back to the hobby!

it looks like you have moderate levels of Ammonia and Nitrite, so cycle should be underway. Just keep testing every few days - once you see nitrates go up and ammonia and nitrite at zero, the initial cycle should be complete.

I also recommend you leave your lights off until you add livestock; for now the lights won't do anything but grow algae (as you've seen).

So the live rock can "quick cycle" your tank, meaning it already has all of the nitrifying bacteria needed to support the nitrogen cycle from some fish. 5lbs of live rock will help to populate the 5lb of dry rock and bioballs. The turbostart will just add to this, but wasn't needed.

You are still mid cycle, it appears. You will be able to detect nitrate at the end of the cycle. Your readings still show 0. The only way to eliminate nitrate is water changes or some other media that's marketed to do so (I would stay away and stay with the tried and true water changes)

OK thanks a lot ... I'll leave lights off, keep testing, and pretty soon add fish.
will the algae or whatever clear up or should I add a CUC?

Welcome to R2R and to saltwater aquaria!

Cycling can be confusing to new reefers, but looks like you are on the right track. As mentioned above, it's quite common for those API test kits to report a false ammonia reading. In your case, it looks like nitrite is down to zero and if that's accurate then the ammonia almost certainly has to be zero as well. If you really want to be sure, consider testing again with another brand of test kits or using a Hanna Checker. You could also bring a water sample to your LFS and have them test it for you.

That said, I'm a fan of patience in this hobby, and there's nothing wrong with giving it another few days to a week or more just to make sure your ammonia and nitrite are zero.

If you are at zero ammonia, then you're ready for your first livestock additions. You mentioned keeping primarily fish, and I just wanted to mention that there are not really a whole lot of saltwater fish appropriate for a 12 gallon AIO (in my opinion). Here's a list from another forum that may give you an idea what can be kept in what sized tank. This list is a bit old, and others may disagree, but it's a starting point when planning your stocking options:

https://www.nano-reef.com/forums/topic/74703-lgreens-ultimate-guide-to-nano-fish/

But, besides fish there really are a whole butch of arguably very cool and interesting inverts you can add, such as snails, crabs and shrimp. And there are some very easy corals to try too. Corals like mushrooms, Zoa's, Xenia and others are very hardy and need only a lower-end lighting system and regular water changes to thrive. Take a look at some R2R member tanks of similar size to get an idea what to stock in your tank.

Good luck!

Thanks a lot FF! yes I know that the 12 gallon will be very limited. I will plan to just have 2 clowns, some CUC, and a few easy corals like you mentioned.

The goal for me is to get back in and comfortable enough to get the bigger tank. then I'd just keep this little one with some coral and a clown or two
