12+ months later and TV still standing. I don’t recommend it but it’s doable. 😂

Unfortunately I topped my 28 gallon biocube aquarium off with a little too much freshwater last night and it caused a drastic oxygen failure within the tank. I woke up this morning and my pair of mated clowns were dead, mated banghai cardinals were dead, and the only survivors gasping for life were my blenny and painted clown goby.

Months and months of work and pairing the clownfish up, watching them every single day when I woke up and seeing their personalities grow and they establish themselves, all gone in under 12 hours. All the levels otherwise are fine, thousands of dollars in coral unharmed.

I feel like an empty husk. Like a giant chunk of my heart was just carved out and I can't stop blaming myself for everything. I loved my fish like they were my absolute best friends and I am having an insanely hard time getting through the morning. My brain is wanting to quit everything but I know I have so much living stuff in my reef tanks, I just can't get over the fact that I killed my friends.

If anyone has any advice I would love to hear it, but otherwise I guess I just needed a place to talk. My heart is overflowing with grief and remorse and I can't stop blaming myself for their deaths.

I have read numerous threads and talked to multiple people in the industry about this but is this tank size okay for a yellow tang, and I know obviously the longer the better.

This is a tank I setup for a client during Covid. They have an autistic daughter who loves the tank. I have serviced it for close to 5 years. It (was) a beautiful, thriving reef full of fish and coral. Now it is empty and their living room flooded.

On Saturday night I got a frantic call from them. Literally screaming in despair as their tank was emptying out onto the floor. The right front seal had come loose. Thankfully, they managed to wrap the edge in duct tape and maintain some water in the tank long enough for help to get there. Also good news is that all of the fish and coral survived and are in my holding tanks. But if they weren’t home? Can you imagine how bad this would have been?

At this point, after dealing with a couple of Red Sea failures myself and seeing the stories from every corner of the internet (including this sub) as well as local stores near me, I will never recommend a Red Sea tank again. To anyone. Buy this brand at your own peril.

This tank was less than 5 years old with almost no signs that this would happen. I checked the seams regularly because I was worried due to the stories, and they never showed much sign of wear (just a tiny bit of necrosis on the tip of the seam, but I’d consider that normal for any aging tank). I feel like I have let my clients down by even recommending this brand of tank to them. I just wanted to share this story so that we have a record of all these tanks failing in case someone wants to start a class action suit against Red Sea. Enough is enough.

These things are straight up pigs

It got knocked into my micromussa by my conch and ate 2-3 heads of it in a few hours. The favia wasnt even fazed

I know eventually most clownfish will pick a host. And I know it’s exactly rare they pick zoas…. But these two just crack me up. Sleeping on their bed of “flowers”.

Since they decided my zoa garden was their home they never venture far from it now.

He looks more like a rock palm tree than a rock flower. I thought these guys liked low light? He’s on my top rock with my montis

They seem to be little tiny cloves… not sure if it’s a pest/weed that I shouldn’t let grow

Hi, as the title suggests I’ve been dealing with an outbreak of red flatworms (Convolutriloba sp.) in my 13.5 gallon AIO reef tank. I’d like to know if there are any predators to control their populations that would fit in my tank. Discounting the filtration chambers I estimate it has a volume of 10 gallons, so it seems that most of the typical recommendations should be ruled out (most sources I’ve seen suggest at least 15 gallons for even small wrasses like six-lines). I’m open to all sorts of suggestions, from fish to invertebrates.

Currently my tank has an emerald crab, pitho crab, blue legged hermit crabs, a sexy anemone shrimp, brittle stars, and several snail species.

I’ve seen velvet nudibranchs as an option, but I would feel bad about getting one and having it die after consuming them all, and risk nuking my tank if he did so, so I’d like to research other options as well.

I am aware of chemical treatments but I would like to keep this as only a last resort. I’ve tried flatworm exit in the past and using it apparently wiped out my pod population, and seemed to almost kill my brittle stars. This appeared to be due to the flatworm exit itself, rather than the tetrodotoxin alone, as i tested it on one of my brittle stars, and i also noticed the invertebrates in my tank reacted before the flatworms one of the times i used it.

I barely do anything to this tank other than some very light feeding and cleaning the glass. There’s a skimmer on the tank but I don’t really turn it on, it’s not really skimming anything out with the low fish load and high coral density

No questions here - just enjoying the ride.

I recently saw this very nice red macroalgae in a YouTuber video and I’d like to get some for my tank but none of the comments in his video or the videos themselves discuss the exact type or name of it. Can you please help?

May 2025 to Today. Dosing AFR and running a kalk stirrer. Tank will be 2 in December. The hammers have grown well for me so far 🤞

What is this purple thing on my candy cane coral? I haven’t seen it move from this spot. It is growing slowly tho. Not sure what it is.

Just looking for some thoughts on the best way to fix this issue?

My calcium is testing at around 310ppm with a brand new salifert kit. My magnesium is at 1320ppm. kH is 8-9.

I have been dosing carbonate to maintain kH.

Tank is 32 gallon + 8 gallon sump.

I have not tested calcium for a while as I dont have any stoney corals except a single candy cane polyp. So I was not expecting Ca to be consumed much.

The tank does have some large soft corals and a bunch of anemones.

Im wondering whats consuming the calcium without consuming magnesium, and what the best way to bring my calcium up might be?

Photo so you can see the corals.

Who has used a storage bin for a sump refugium? I dont have a drilled tank, nor a good stand to have a sump under.

What would the main issues, hurdles be using a storage bin, a good one...

Thanks

I saw that UNS has their own refugium insert with built-in housing for a light (which is dope) and I've heard that it's compatible with other brands' AIOs but what are some other options for hiding a refugium in an AIO? I'm guessing a model with sump/filtration in the back would allow for more than a side mounted one?

How are we looking on flow? Just changed to a Gmp10/40 combo and trying to find a sweet spot

Lights have been ramping down so not extended much as normal

Just got a new coral and this guy saw moving on the box when i came home. Is it okay to put him in my tank? Looks pretty cool.

These are currently my parameters. I have a lps softy tank and the salinity is 1.024. My question is what is the most simple way to raise my alk calc and mag? would it be tropic marin all for reef?

does the tank look healthy? genuine question because this is my first saltwater tank, even the lights are chihiros freshwater that i set to blue spectrum (changed to normal for this video). tank size is shallow 100x45x25cm (112liters).

majorities of softies with 3 LPS (duncan, blastomussa and goniopora). all the corals look good in my eyes but as this is my first rodeo, i don't know better. also i feel the diatom and algae a bit much? then the wavemaker, what i have right now is the jebao scp-70 and even i already set the power to only one and slowest wave interval setting there are no low flow in the tank i think, as you can see on the goniopora, duncan and some zoas and mushrooms. did i buy the wrong model for my type of tank?

i don't have any water parameter test kit yet, what i know is salinity 1.025 and temp 25.5celcius. both stable.

need insight from everyone here, thank you before!
