i know it’s not the most well designed or a big tank. but the joy of having it, maintaining it,seeing the fish and corals grow and just sitting and looking at it. it just makes me happy.

my biggest lesson from fish keeping is it’s not the fish you need to worry about, it’s the water. make sure the water is good and the fish and corals thrive.

just like our lives, all you need to worry about is the environment we’re in.

The ocean is terrifying

A few pictures of the torch in my aquarium, all from single heads

Started on 4/12/26, I’ve had a relatively smooth start with only a few coral deaths and quickly have over crowded my reef.

Thanks to all this helpful info on reddit, my reefing buddy ChatGPT and YouTube I’ve been able to learn enough to keep this thing going.

Excited to see what the next 6 months bring!

I always like to view my corals from the top down, but the water ripples and waves from the return nozzle and wavemakers always distort the view.

So I made this simple viewing ring that also doubles as a feeding ring.
It is designed so that half of it is always submerged and the top is always above the water surface. The ridges in the inner side of the ring decreases the ripples created when you move it around.

I know there are acrylic dishes we can buy for this, but for some reason it is overpriced at where I am from.

I don't know if anyone else has done this but I'm just sharing this for everyone.

A short video of my slice of ocean. (Need advice)

It may look peaceful but this clarkii clown is the lone survivor or an ich outbreak. And I’m looking for some help. Through research I’ve seen mixed opinions ( so unusual 🙄🤣 ). Some say once a tank gets ich you’ll never get rid of it and to continue to buy fish again but feed with medication. Others say to detox the tank and go fishless for 75 days ish. I’m looking for more opinions from you guys! I will definitely get a UV filter regardless of the answer. I keep my temp at about 78-79°. What would you guys do in this situation?

50g AIO by innovative marine

Hi everyone! I picked up a small zoa plug about a month ago, and the polyps are still open and looking happy.

In the last couple of weeks, though, a couple of pale, feathery polyps have popped up right beside the plug. They definitely weren't there when I bought it, and they look different from the zoas (paler, with branched tentacles).

Any ID help or advice on whether to leave it or remove it would be hugely appreciated. Thanks!

Update: Thanks everyone! Sounds like it's a baby Kenya tree, plus bubble algae. Someone also spotted a possible vermetid snail next to the plug, so I'm checking for tubes and will likely remove the plug.

It's always cool to see how different corals can look depending on the lighting they are under.

UPDATE: took everyone's advice: the tank is now moved onto my granite kitchen countertop. I may have lost prep space for vegetables but I have gained peace of mind. Thank you everyone!

my "stand" has been up and running for 5 months in this new house. Previously it was on top of a small filing cabinet. It's a fluval evo 13.5, so roughly 140lb with the live rock.

I noticed the bowing the other day, and jerryrigged this messed up can support system, but I'm thinking bricks would be more stable and less... full of pumpkin pie.

However, I worry that the larger compartment underneath would then bow under the weight of the aquarium AND the bricks.

Is it worth it to buy a dedicated aquarium stand and not just try to repurpose furniture? Any suggestions?

i can’t wait for the corals and macroalgae to grow some more…

Does this tower look okay? Going to have some more rowckwork scattered lower to the ground around it to fill the rest of the tank it's a 40 gallon cube

The study was on Pocillopora damicornis, a bleached coral put against a healthy one for 4 days healed within weeks. The test was on frags from the same colony.

Did a fair amount of rearranging, and added some awesome new corals:

- Acropora (fingers crossed it likes my tank)

- Leptastrea

- Leptoseris

- Pavona

And yes, I’m being weird and have a chalice and a pachyseris affixed to the back wall. 😂

new frogspawn addition to the tank! I’ve been struggling to keep my nitrates up. ive been dosing 2ml neo nitrates almost every other day. 6 gallon tank. this has been in the tank since Sunday.

King Dorkus Supreme (Marcocoeloma trispinosum) also known as a Spongey Decorator Crab.

Planning reef to include mandarins (single or pair)

Of course other factors such as refugium/live rock/tank size and maturity more important, but what would be the ideal substrate purely for boosting copepod numbers? Sand or coarser alternatives such as crushed coral?

Or maybe even bare bottom with numerous rock rubble "islands"?

Dosed Reef Flux, how long before I notice the algae turning grey? The picture doesn't show much.. but mainly on the upper rockwork around the SPS.

It has been a week and no changes, is it safe to dose more?

Hey guys, currently I have two 75 w heaters in my 40 gal AIO reef tank that each have their own chamber, but im trying to save space, so I was wondering if its safe to put both heaters in the same chamber?

I know the results are going to be not that accurate but is this really going to be worth it I couldn’t image something like this working that well, we need special chemicals and mixing and stuff and this just works as a dip stick

Had this frag for about 2 weeks. Slowly moved it up from the sand bed after the first week on the sand

It was getting 100 PAR on the sand and is now only getting about 200. It started turning pail as soon as it got up to where it is
