need help

Hey, started seeing some spotting on the sand that looked like rust. Now it grew into this, looks kind of like hair. I'm new to the hobby and the tank is maybe 1 month old. I also tested SiO2 and it's quite high (>6). I hope it's Diatoms but could someone else have a look?

9 days ago I brought home what the shop called a kingspawn, a super fancy frogspawn with massive polyp size. It’s just a single head but this is what it looked like the day after I brought it home: The day after that I decided to feed it a small chunk of prawn just like I give to my nems, and...

I need help with algae ID for two algae that hitch hiked into my tank. I dip and treat with h2o2. But these made it through. Fluconozol knocked them back but they survived enough to come back. The one is not hair or bryopsis. It's almost like chaeto texture, but it's not chaeto. Let me know what...

First post, I’m rather new to the hobby. I’ve had 20 gal tank for a year and recently upgraded to 40 gal. To accompany my two clownfish and I bought a blue eyed tang. When I brought him home I noticed he had a faint red spot that appeared to be internal. Either on his hepatic portal system, or...

Alright I need some help identifying this thing. It's a white fuzzy ball looking thing. Riding around on my snail. Any help is appreciate it.

My tank is getting overrun with what I believe to be dinoflagellates. I know small/new tank syndrome is probably part of it, but is there any way to get rid of it? I heard that raising nitrates and phosphates could help, but that’s a scary idea to me as I have some sensitive animals in the tank...

I originally ordered 3D printed media trays with flow direction that I would use for media bags in chamber 1 and a refugium in chamber 2… the story on that is in my other post here: https://www.reef2reef.com/threads/refugium-build-decision-for-fluval-evo-13-5.1061800/#post-12656820 I still...

I don’t know what happened, fish eyes are now cloudy and underneath whiting with a pale coat. I did some research and I believe it’s brook disease but I’m not 100% sure and even if it is, it’s 12:38 am and nothing is open what can I do? And is this the disease I’m looking at? Please help, thank...

would too many water changes be bad for a tank or would it be fine?

[Little bit of info/background]: I had this 16g tank running, empty, for months. It never had lights on, only sunlight, and I thought it was cycled based on the ammonia/nitrate being none or low. A couple weeks ago my poor clown was dying and I tried to save him, so I put him in this tank (the...

Please help me my maroon clown has white stringy poop the Tank has been going down hill for a while and I’ve been trying to fix it but there’s a lot of issues. I have a brand new tank I’m trying to put him in. There’s nothing in it and I want him to go in there. I took him out of the ******...

Someone please tell me what’s wrong with my snail! I have two (turbo?) snails, one is acting completely fine! There’s plenty of algae in here for them too. This one was upside down in the sand last night, seeming to try and grab onto the rock. I moved him next to a rock so he could easily get...

Hey y’all!! Hope everyone is well. I have a 16g biocube I just set up, it’s a bare bottom with dry rock. I put some biospira in it but I don’t have any fish in there. i have a tank running that has a fish in it but I got it from my dad about 9 months ago, already set up with a fish & CUC, so...

Help please!!! This stringy thing is attached to my clown’s underside, directly under where the middle white line is located on his body. I have a bunch of pictures for y’all. Obviously the string is moving around in the water but it keeps getting longer! It’s got a thick piece at the bottom and...

I recently got a tiger angelfish in my tank and he looks really healthy and is active but he is not eating any of the food I put in the tank. I have it in a 120 with a gem tang and a really small clownfish. They are the only fish in the take and the angelfish already seems to have taken over the...

Hey everyone! This is my very first saltwater tank and I’m so excited. I have always wanted one! A little background, it’s a 16gal BioCube, previously owned. My dad got it for me, since he decided to downsize his 32gal (which he still hasn’t done yet lol), and didn’t change the rock, sand, or...

I am looking for a place to buy some frostbite clownfish I would love an orange/white/blue and a black/white/blue. Does anybody know of an online store or breeder? What about LFS in Phoenix az? I have looked around and found 1 place that sells them but I haven’t received any info for shipping...

Hello everyone, everyone here was great helping me start with the basics. I need your help again please!!! I have a Red Sea 750 XXL and I just filled it for the first time and while I think the sump may need another 5 or so gallons I started the return pump and the skimmer just to make sure it...

We got this trumpet coral March 21st. We dipped it in iodine when we first got it and started it in the bottom of the tank. The first picture (in the dark) was taken on March 26 - showing it's feeders. On March 28th we moved it to the middle of the tank (second pic shows it's location). When we...

Hi everyone, So I bought this new zoa colony at an LFS where I have been once before and it's not doing too great. I bought the colony Saturday November 28th 2020 so I've had it for almost a week now. The issues: - Less and less polyps open up every day - White strings appearing at the base of...

I know I will need to test before doing additives. I don't have a LFS nearby and want to get some supplies in advance. My tank has been cycling and I want to be ready as I stock my tank. What additives should I have on hand for fish, soft, sps, and lps reef tank? I obviously won't have all of...

It’s a black widow anemone that is hoasting a maroon clown fish. It has been in the tank for about 2 day and I also have another anemone in the tank that is really healthy could it be that the clownfish is being to hard with it
