I’m working on turning my nano reef into a macroalgae tank for dwarf seahorses. It’s been up for a year now and these little things have been in there for about 8 months, basically since i added the one extra piece of rock that they’re on. There’s only a few of them on that one rock and none of...

I whant to get a new tank for a tang but I would only be able to afford a 40 gallon that has a length of 48 inches buy people say you need 75 gallon tank for even the smallest of tangs but I have looked and there the same length like why would I get a way more expensive tank if it’s the same length?

i have a 60cm cube display and a 40 cm secondary tank, mixed tanks, but since the last week some corals health has been impacted, mainly my 24k torch has lost color and tissue in one spot, two recently acquired acropora frags has RTN and one gonipora also died, the other corals look happy and...

Hi I got this fish from a friend and have been quarantining it with other fish from the system and 2 fish from another system. I usually never cross qt fish but they had been separately visually qt for several weeks prior with no symptoms of anything. I did however have 2 small damsels and a...

Hey other reefers, I just picked up a 300xl and noticed after setting it up a chip on the front glass at the bottom of the tank…. I packed silicon into the area and tried putting some on the inside in a panic. I’m not sure if I should trust it long term, what do you guys think?

Hey everyone! So this tank has been up and running for about two months now. Everything was going smoothly at first, but then my auto feeder accidentally dumped more food than it should have—and I didn’t catch it right away. Next thing I knew, I had a bloom in the tank. I added a UV...

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...
