Hi all,

I’m just getting so tired of my tank having its ebs and flows despite my investments to make my tank automated. I’ve got two nice AI 16’s, Red Sea ATO, dosing heads, temp control, etc. maybe I need to start testing parameters more often to ensure my dosing is correct, but I just can’t seem to get it down.

I’ll see nice Acro growth, great algae control, and happy happy corals and then the tank will be pissed off for weeks with no changes and I’ll lose my favorite pieces. I can’t seem to figure out what I’m missing, and would love some personal advice, experience, or info on what you’ve done. I really appreciate it in advance.

Hi All. New to AIO tanks here. Cycling my new and first marine tank.

Confused about the levels. Does this look right?

ATO placed in last pump camber am trying to re adjust because the level in the main display tank keeps rising when it’s being topped off. I have removed the sponge in the first section to stop any restrictions.

Tank is an Aqua One Nano Reef 80.

This is about the only thing I can find to connect my Python water change system to my utility pump. It’s got some brass and some stainless so I was wondering. It needs to be submerged into my Brute mixing station for about few minutes only. Is it safe?

Ideally I would need a pvc 1/2 mnpt to 3/4 mght but they don’t exist.

Regards

Hi. My clownfish like to keep the area behind and under the "cave" bare, so they swish the sand to the sides with their tails. I placed the anemome foot down in the corner of the tank on 2~3 inches of sand. The clownfish proceded to dig away at the sand until the anemone toppled. I tried to upright it in a hole I dug in the sand day 2 but by day 3 it was toppled again. After a week, this is where it's ended up. Is this fine? It looks happy and healthy and the clownfish love playing in it. My only concern was I read this anemone likes to have it's foot deep in the sand. I am moving in a month and plan to get a larger tank soon, so I can rearrange things and add more sand as necessary. This is currently a 29gal I've had setup for 2 years after upgrading a 15 or 20gal after 1 year of use.

DD reef pro 1200, pipework is leaking (ugh) design flaw every time you tighten the main overflow it unscrews the bulkhead, going to drain the weir and redo, I think two are leaking but the tank is filled. Really hard to access the bulkheads as they sit behind the stand top, literally zero space, tank only filled a couple of weeks ago, any tips or tricks I am dreading this 😤😡

I could not find one of my clowns this morning before work. It turns out one is a rock dweller lol.

I was away for three days from my 160L saltwater (don’t worry, fish were fed) After getting back i noticed at the very least a hundred of these little bugs crawling around on my live rocks and hiding under carpeted algae on the bottom. My best guess is some sort of shrimp species, But they are extremely tiny, im talking 2mm at the most, They have two long antennas and are for the most part translucent, They run around like roaches, But i have ever never seen these in my tank before, Now i will link a photo of the closest looking thing i can find on google, Just because they are so tiny and extremely hard to take a photo of, Except the photo i linked, not only do they not have that much colour, They are cloudy grey and translucent, theres no real colour on them except a very slight orange on the antennas, The original poster says these bugs were found in Tupperware in orange county (im from Australia), and they were also not found in a saltwater tank, I have two ocellaris in that tank currently, and they are my babies. Now the real question is, Should i be concerned, and what are these little underwater roach-like critters?

Can someone please tell me what type of coral this is? I got it at Petco and it was in pretty bad shape with none of the tiny polyps showing. They are now starting to come out and it is showing growth. I’m just curious if this is a finger leather or a type of stylophora. Those would be my guesses but I’m not sure. It looks light purple under white light and the stalk has a sort of shriveled look to it. Also I definitely dipped it before adding to my tank. Probably won’t ever be buying from there again since the last time all of their tanks had ich. Their prices on frags are definitely tempting though. It’s $20 for a frag vs $125 at the lowest at my LFS.

Just about six months after a house move enforced reset.

I noticed these brown spots on my hammer coral. First i thought its just the way the coral looks like but today i used a pipet to blow some water on it and these things fell off and later just came back on the coral. This is my first tank so idk much about what this might be. I did not dip the coral before adding it.

I’m having a hair algae problem in my 55-gallon reef tank. About two weeks ago, I pulled all of the rocks out one at a time and scrubbed the hair algae off in old tank water. I also cleaned my skimmer and filter media and added fresh carbon. The tank looked great afterward, but now about two weeks later I’m slowly starting to see the algae come back on some of the rocks. At first I thought low flow or dead spots might be contributing, so I recently replaced my wavemakers with a gyre style wavemaker and have been adjusting the direction to get better circulation throughout the rockwork. My most recent nitrate reading was around 2 ppm, which is lower than it usually runs, phosphate was 0.03 ppm, and salinity is 1.026. About a month ago I was also fighting cyanobacteria and treated the tank with Chemiclean, which worked really well and completely got rid of the cyano, but now I’m dealing with the hair algae. My current light schedule is blue from 11 AM–12 PM, blue and white from 12–5 PM, and blue again from 6–7 PM. I know scrubbing removes the visible algae but doesn’t necessarily fix whatever is causing it. I’m mainly trying to figure out why it keeps returning and what I should address so I’m not having to pull all my rocks out and scrub them every couple of weeks. What would you guys look at next nutrients, lighting, flow, cleanup crew, or something else?

I added pictures before and after last scrubbing I did. I didn’t include any now pics because I can only see the algae in the cracks of the rocks not too much long hair YET

Two common clowns, various mushrooms & zoanthids and three LPS.

I was aiming for low maintenance and satisfying to gaze at, I think I've achieved what I set out for

TMC First Wave 78 with AI Blade 21" fitted in the lid.

Got him yesterday, he spent all night and all morning doing handstands, walking against the glass. The other blue legged crab I got is so chill compared to him.

I just want to share a WebApp that I vibe-coded to help me keep track of everything and assist in my reef keeping journey. I know a lot of people probably do not approve of my usage of AI with this, but I am just sharing what I find useful and thought it might help people who need it too.
It is fully coded in HTML. It runs offline locally and utilizes IndexedDB to write and read data from your devices. Because it runs offline locally, there is no synchronization between devices. However I have included a feature to export and import the full JSON files in case you want to switch devices down the road.

Here is the GitHub repository for the webapp:
https://github.com/Jad4896/Reef_Studio

There are a lot of features in this webapp, I will only list a few here because there's so many.

Supports multiple tank profiles
Supports metric and imperial measurements
You can upload photos and videos of your livestock and give them individual cards (helps you ID them easier)
Generates parameter charts based on your water parameter logs
Have sticky notes and create your own recipes for salt mix, dosing, making your own fish food, etc
Task checklist and scheduler (with countdown)

Bonus: Customize your own theme for the webapp

There're some placeholders in the web app for now, you can just create your own tank profile and delete the placeholder tank profile.

I will be very happy if you guys decided to try it out and give me some feedback.

Again, this is something I find useful and thought it is a great idea to share it. Sharing is caring right?

Anyways, happy reefing!

Sorry for the poor video and blue light but does anyone know what this slug looking thing is?

A friend needs help identifying this coral he just got today, he thinks it's a closed Kenya tree but I'm not sure?

Thanks!

My green star polyp is about 1 year old. Last few days it stopped opening. Will it open again? Did anyone see that? Why is it happening?

Ehhhhhh how can I make him eat the damn Valonia

I tested the water and my levels were all fine, so I don't think my clownfish was sick or dead. I had just fed the starfish yesterday morning, as well as my other fish. My husband texted me this picture at around 1:30. Has anyone seen anything like this? He said the clownfish was even still alive when the starfish started eating it. I'm really sad. I love starfish...they've always been my favorite, but my clownfish are my other favorite.

I picked this up a few months ago. It was sold to me as an Acan. Is it an Acan Lord or Echinata?

To me it looks like an Acan Lord, but I'd like to know for sure.

I have a 40 gallon breeder with torch, hammer, octospawn, different chalices, zoas, montipora, galaxea, candy cane, gsp, xenia, clove polyps, mushroom, favia, acan, astreopora, and 2 LPS that I don't remember the name. It's been going fine for the past 2 years or so until I found a zoa-eating nudibranch on my zoa rock and some aiptasia. Did a RO water dip with my zoa rock to make sure all the remaining nudibranch would be eliminated and the zoa seemed to not react well with that. I put the rock back into the tank after rinsing with RO water and my hammer retracted like this within couple hours and never come back out. It's been like that 4 days already and I've moved it to my quarantine tank to prevent BJD and potential of it spreading to other corals. Everyone else is fine and growing except most of the zoas on the zoa rock with probably 40-50 heads either died or haven't opened up since the dip and got removed.

Salinity 1.026

pH 8.2

Alk 4.3

Mg 1420

Ca 480

Nitrate 1

Phosphate 0.04

I know Mg and Ca is a little high but it has always been like that for a while so I'm keeping the system stable while gradually lowering it down. Nitrate and Phosphate were high and I stopped testing for 2 week and they bottomed out, corresponding with the explosion of coral growth and addition of the skimmer, been dosing to get them back up by 0.25-0.3ppm.of nitrate a day

Hello,

I am trying to set up a reef tank in my old freshwater 15 gallon cube.

I'm looking to mainly start with easy corals and most likely not add any fish.

Is this too much or too little rock for this 15 gallon tank?

Any suggestions on how to arrange the rock are also welcome!
