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...

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...

Good afternoon! My saltwater tank has been up since.. November(?) of last year. I waited a long time to ensure it cycled, used live sand, dry rock, lots of filter media, etc. This isn't my first tank so I have experience, though I am not an expert by any means. I've had a moon jelly tank, and...

Since adding a new, stronger light, the cabbage coral has closed up, and now it’s bubbling. I brushed and blew off the bubbles on its surface, but all these bubbles are under the skin and inside the flesh. Is this because it’s receiving too much light and wasn’t acclimated to the new lighting...

Hey everyone, I picked up my first acro frags 1 week ago and they’re not looking too good. The purple 1 is in worse shape but now today even the green 1 on the left in the second picture seems to have some tissue loss now. Looking for advice on what to do to save them if possible, or what to do...
