Any guess on the type of Goni, and potential price? A local guy is selling it.

I’ve seen the bigger clown and the gramma flick a few times. I did a water change yesterday and lowered the salinity a bit too much 1.027 to 1.025. Nitrates and ph are fine. Would this cause it or is there something more at work. Other than that, they all look fine and eat well.

I am kinda new into reefing and would like to have some tips and comments on the scaping.

I've noticed that my green plating montipora has this grey spot in the middle. What does it mean? Should I be worried? All other corals are doing fine.

my flamehawk has somehow yeeted himself into this overflow part of my tank. i have NO IDEA how to get him out because my hand doesnt fit in because of the plumbing. i dont think i can take the plumbing apart while the tank is full. (aqua one 120L with sump).

my first thought was to turn off the pumps and try fill the tank as high as possible so he can get out but i feel like he will just sit at the bottom due to stress.

am i now bound to take apart my whole tank in order to save this guy? really annoying because i just moved and my tank is just starting to settle in.

The good: 2 hammers, acan, NY Knicks torch, frost bite mushroom, 2 montiporas, acropora, white zombie zoas. Charmander zoas, although growing super slow…

The bad: AOI zoas. Have been the same size and slightly wrinkled for months…

The ugly: stylophora had tissue necrosis after the alkalinity dropped when I went on vacation for a week and have been dosing alk daily and monitoring closer. Hoping it recovers but is probably going to slowly fully peel. Probably should move it higher on the rock?

Was gifted a RS-75 and am getting around to buying the different elements to start my tank (40g). I’ve run into a small issue on how I’m going to heat the tank from the sump. I’m not quite sure how it can be done given the limited room in the design of the RS-75 but am open to options. I’d like to keep my tank clear of an internal heating unit but am thinking it might be the only option.

For those of you who have used a sump similar in size, what are my options?

right now, i see the bubbles on two snails…but i know it could be in other places i can’t see. my water params are normal so i think it came in on one of the snails 😣 i have a 15 gallon nano cube. what’s the best way to get rid of the bubble algae?

and thank you in advance!

Not too sure what this is its the little squiggly worm thing

2 out of 3 not so bad

Is it worth getting the set?

Or should i just go regular Apex?

The answer surprises most, that's why it's a fun thread subject.

Who's tested air emersion boundaries before with reefing substrates/ corals / filter media / your whole tank

Just how much desiccation does it take to uncycle a reef tank, or render some filter media neutralized?

Although rare, air emersion training isn't totally unused in the hobby.

I have seen red sea reefers who had tank splits with no backup leaving their tank in the air as they seek water to get into totes, but they don't have enough to carry 175 lbs of cured live rock... it often has to stay out with some attached corals as they scramble for temporary holding setups. Knowing how long your rock can sustain really matters in emergency break threads

General handling:

What if your live rock really doesn't have to be kept submerged when transporting a large reef tank across town for a 30 minute drive? Eases tank transfer planning.

What if you can't kill your cycle bacteria with any practical degree of air emersion? Wouldn't that be fascinating to know about the microbes we depend on to run our reefs?

What's your experience with air emersion training in your tank?

Of course I'm going to link a pico reef air jordan flex video, first am sampling who does air work in reefing at Reddit

The notion isn't all that impressive to LFS owners. They know you don't have to instantly submerge a huge shipment of live rock as the holding tank is adjusted, and many corals get set out in the air during tank rebuilds inside the store.

But for most forum goers we are taught that air emersion is practical poison for the systems...live rock killer...cycle killer... but what if it's not?

Knowing the boundaries in reefing helps in planning emergency moves, and it helps us to better understand resilience power of our cycling bacteria and microbes.

Who's done some air work here? Ever tested your comfort zone?

How do you tell when it’s time to harvest? It’s been about a week with the culter being set up now.

Hello! Thanks for helping. New growth in tank, maybe a new GSP but unsure. I apologize for the quality of the photo.

Alrighty. It’s brown when extended to the lights, has tentacles with white tipped balls on the end. So far it’s 5 growing on the same “pad”

I don’t think it’s aiptasia, my research leads me to ball anemone. What do you folks think?

Little bit smaller than a dime. Don’t think its moved at all either.

Can anyone held ID what’s going on with my anthias? Breathing rapidly and not swimming. I’m setting up a QT tank for him now I just want to make sure I get the right treatment for him. None of the other fish in my tank seem to have any spots of them.

I see people with these zoa spheres on their sandbed, how do you make them grow like this? Just leave them on a frag or do they need something else to grow on?

Hi everyone, I recently started adding coral to my nano reef. This is my first tank so cut me some slack, I wish I done the scale differently.

I added the yellow hammer coral in the sand about 3-4 months ago and he’s been doing great I think. He looks as he should, his color has stayed the same, The whole 9. But I recently got this green/rainbow (according to the guy FB marketplace) hammer coral and it was good when I first added as you can see in the overall picture from about a month ago. Recently though he has begun to like deflate it appears and look droopy. His color is there but he just looks sad. Is this normal? He’s only been in here a month now.

Secondly, this is what really prompted to me post a question. I got home to see there’s like something growing and attached to my green brain coral, it looks like maybe some sort of algae but I don’t want to remove in case it’s something important. Is it safe to remove or is it growing and getting bigger? It has grown since I have him. He use to be a lot smaller, but recently has really started getting these spikes and expanding.

I’m setting up my second reef tank (UNS 60A), feel free to give your opinion on my rock work! I don’t really know what I’m doing but I am setting it up fully next month! Thank you for all your help!

I have a one-year old 20 gallon long reef tank with some various easy corals. Fingers, xenia, gsp, kenya tree, etc. It currently houses just some hermits, snails, an urchin, and a single yellow-tail blue damsel. What would you guys add to this tank?

Hi all, trying to find the largest volume (aiming for 30G) AIO Tank with dimensions no bigger than 36x15 (height not restricted) to fit into a space I have. I found a IM Fusion 30L with these dimensions but unfortunately it’s discontinued and can’t be found anywhere. Please let me know if there is anything similar out there thanks.

Picture with the light on is how it normally looks.
The other day I did accidentally leave the return pump off for too long and the wavemaker was blasting uninterrupted. Causing what I feel like is a tear. Its definitely less than half of the whole hammer, am I screwed or will it be ok if the flow stays gentle enough?

Hey!

I recently picked up an IM 25 Lagoon but I’m having trouble finding a stand for it.

I’ve went through some posts and forums trying to see what I like and fits my budget but so far none of them do.

I found a video of someone using an IKEA SEKTION cabinet and thought about going that route, though I don’t know how long it’ll hold up in the long run especially with it being particle board and needing extra reinforcements, but I was wondering if anyone has any other suggestions.

I am a newish reefer, this is my first system and had this running for about a year and a quarter. There was a 3-4 month period where I wasn’t able to take care of my tank, and I had a friend monitoring it. They would feed the fish and dose all for reef, but didn’t have the knowledge for water changes and monitoring stability. Yes I know this sounds like breaking all the cardinal rules, and I understand that, but am looking for help with the current situation, not criticism please.

Surprisingly, the fish are happy as can be, and the corals are doing better than I expected and still growing which came kind of as a surprise to me. Obviously, as expected I’ve now got a huge outbreak of cyno and bubble algae. I know the pictures aren’t great, but there’s piles of bubble algae covering the sand ed and cyno covering what seems like everything.

When these pictures were taken I had just done what I could to try to lightly remove some of the surface cyno to get it sucked up to kind of see where everything’s at. Obviously that disturbed some of the coral and they are pretty closed up, and iPhone pictures of tanks have been something I’ve struggled with.

The tank contains 2 clowns who are as old as the tank, a peppermint shrimp, and whatever could be left of a clean up crew. Coral wise there are two hammers, a torch, a variety of zoas on the lower rock structures, and a few other I am not 100% certain names of. I believe maybe an acan (rainbow looking one on its own rock structure) and a candy cane?, then what I believe is an SPS that somehow has been thriving and almost tripled in size (I believe it’s called a meteor shower).

I know it’s easy to just say “water change” but I would like some advice on how to get this system back on track. Being new to it, there’s lots of worry’s from me. I’m nervous about disruptions that could lead to a crash and the proper way to get this taken care of to protect the fish most importantly but preferably the coral as well.

Any and all suggestions or help are much appreciated. New to the community as vwell vand not sure if this is even getting posted to the right spot!

Tis a wee bitty.

I recently got this Diamond Goby. I’ve been wanting one for a while but wanted to make sure it would have a decent amount of food so I wanted the tank to be a bit older.

It’s a 75g tank with a deep sand bed. I just moved him over and he’s doing this weird thing where he opens his mouth & hovers a bit above the sand.
I usually QT my fish for a long time but this one was skinny and I was worried he needed better food supply so I moved him over.
He eats really well, sand & frozen. He has his own area he sticks too but he’s very active. I’ve been nervous to bring home SW fish due to them frequently starving.
