So I have no clue what this stuff is but from what I’ve read I believe it’s cyano from me over feeding (I still have no clue how much or how often to feed my fish or if I should be feeding with the pumps on or off or really anything but I just got a very diverse clean up crew so hopefully...

I bought a Chinese Hailea Chiller from the local Aquarium shop and the guy told me to get a extra pump to pump water in and out of Chiller, but my bottom filter tank is too small to add a extra pump as the middle spot of the filtration tank has already been taken up by the Skimmer. My tank is...

I’ve now officially lost 2 emerald crabs the EXACT same way within a week of purchasing, like 2 days ago I walked into my room to see 1 on its back next to a rock twitching and then 2 days later he was dead, last night I saw my other emerald crab holding onto the side of a rock with only its...

Hey there, Super excited to get to chat with you all. I am new to the hobby, but I come from a background of biochemistry and aqua culture during my undergraduate. I currently own a 10G tank with live rock, live sand, x6 snails and an oscellaris clownfish. I’m running the Fluval marine...

So I started my reefing journey back in maybe August of last year. I’ve been pretty good about testing my nutrients and dosing what was needed etc and of course had a couple of mishaps where Alk or other nutrients were lower than what they should’ve been. However, despite my levels being pretty...

So I got 2 emerald crabs roughly 4 days ago and they’ve been doing completely fine, but today I walked into my fish room to see this one on its back twitching and holding its one leg? It’s next to a rock so I know it’s not stuck and the other emerald crab and all other fish and inverts are doing...

Hey all! My tank has had fish and corals since March 7th. I added 3 different brands of live nitrifying bacteria plus added massive heavily seeded live rocks during the cycling phase. Nearly one month of fish, corals and inverts with daily feedings of frozen reef frenzy and nori seaweed, and...

I got my hydros launch in the mail today, but it won’t connect to wifi. It has the yellow blinking wifi LED and when I set it up it’s stuck on “Installing UserID” If I restart the app it does show it in my devices, but it won’t load the status. It’s right next to my Control XP8 which is...

I've had a 13.5 fluval for 4.5 months and I feel like I've been making every single recommendation possible to get over the "ugly stage" but I'm not sure it's the ugly stage at this point, rather than just a nuisance algae and diatom or dino problem. So my sand gets real brown during the day...

So im currently looking into buying a 75 gallon tank from petco with the upcoming 50% off discount to eventually turn into my DT (Granted i plan to probably wait a few months as my 25g has only been cycled for roughly 2 months and i feel that might mess up all my current work so ill probably...

Hey everyone does anyone have an idea what this algae is? Is very easy to pull off the rocks, but it also forms in balls on the sand. Don’t have any idea what it is and it just showed up about a month ago. If someone knows what it is, what is my best solution to fix it? It looks reddish...

I'm very confused on how to get the proper level for the water in my fiji cube 1200 I'm still dry and just wanting to make sure this tank is silent as possible. Only thing i can think of is having the dursa pipe sticking above the box and overflow and have the emergency below it. (My worry is...

This morning I turned on the lights in my 10g frag tank to find the water slightly ”milky“ and the fish breathing super fast and acting somewhat erratic. This comes after a complete crash in my main 32g which I am yet to find a cause for (although a botched flatworm exit treatment or bad rodi...

I picked up both of these clowns from my local fish store. They didn’t order them, so they didn’t appear on the packing slip and the employees and no clue what kind they were. They sold both of them to me for $40 each, and I’m curious what they are and if I got a good deal?

Hi! I recently started up a salt water tank about a month ago, currently has 2 clownfish, gsp, and a small hammer frag. I have recently discovered coralline algae on my line rock, wave maker and heater. I heard that it means your water is stable? Is this so? I’m currently also using a Fluval...

Hello. I'm wondering if anyone has advice on what you do with my royal gramma. It's been in quarantine healthy after almost 30 days and suddenly it looked like this overnight. Scales were falling off and it looked like it had an intestinal blockage. It's alive but barely. I'm wondering if it can...

i have seen to found some hitchhikers under my corals. Do you guys have any idea what it is and how to get rid of it.

Hello, this is the first time buying coral online and I want to know if these are hitchhikers. If they are how do I get rid of them without damaging the coral.

Picked up this guy at my lfs. Concerned about its stress level as it’s been hanging in the back of the tank since Sunday breathing like this. Haven’t noted him pecking at anything. Per lfs he was doing well and even eating Pac Pods. Moved him to this acclimation box today. How long do they...

Hey everyone! I’m new to the saltwater side of the hobby and wanted to share my journey so far—plus get some advice and reassurance from the pros here on Reef2Reef! I’ve been keeping freshwater tanks for a while, but about 3 weeks ago, I finally took the plunge into saltwater and set up my...

Woke up at 4am to beeping. Immediately checked phone. Which is nice to not have to get out of bed if its something stupid. NOPE. Sensor says unknown. And ATO pump went into fallback which I never configured or realized I should have. Thankfully it did not dump a lot of RODI in. Salinity only...

Hi everyone, I currently have a problem with my two tangs. They are both juvenile and from biota! Super great fish although sometimes they don't get along. Now fast forward I purchases a copper band butterfly although I knew the risks I asked to seem them eat and this one was a very sporadic...

Can someone let me know if this octospawn is supposed to act/look like this? I have had it for 2.5 weeks now and got it in the same shipment from aquaSD (both hammers and bubble coral). As you can see, the hammers and bubble are doing great— but my octospawn’s polyps don’t extend further than...

So, I just bought NeoPhos, and this is to help me get rid of diatoms. I was told I need to raise my phosphates levels to .1 PPM, and I am not dosing yet because I need some other dosings to go with this. It says on the bottle, word for word, "Apple NeoPhos as directed below to attain a minimum...
