sand

Hey, I’ve had a diatom outbreak recently but fixed it, it was all because of my water. But there were diatoms all over it and I haven’t been able to get them off even with picking them off I cannot get them. And I’m not sure what to do because it has not opened up in a while, I’ve never actually...

After a few years, my sandbed, especially in the front of my tank has been almost worn out, during my wc this weekend I exposed the bottom, so it’s time to add some more sand, but I’m not sure where to start. Some places I’ve seen say to use live sand to not suffocate the bacteria in the sand...

My grouper has been rubbing himself on the sand and he has been eating quite well also he has this mark I thought at first was just his coloring it’s not identical to the other side hes hard to tell I was thinking the temperature because I have a glass lid heat gets trapped so it gets hot like...

I am about to set up my tank and have the rocks, sand, but no water yet. I will have the water ready to be put into the tank in 2 days max, possibly tomorrow. My question is, is it okay to put the sand and rock in now and leave it without water for a day or two. I know the rock is okay but my...

What is this, there is something on my rocks and in the sand that has brown red tint and does not look normal.

Hello! I got a new pistol shrimp last night, a candy stripe pistol shrimp. His name is Lazarus. I've seen Lazarus try to dig, but unfortunately, the digging doesn't seem to be working right. All the sand slides back down when he tries to take it out. He just manages to make a big cone. In...

I used my city water to clean my 80 pounds of sand (Caribsea grade sand) I know this is frowned apon. My water has chloramine in it and I used the city water to clean it, I drained the water out as much as I could and put the wet sand in my 90 gallon aquarium. There was very little water in the...

I just got a blenny to try and help with some algae Issues and I am wondering if the sand has too much shell/rocks for the blenny. last week I took about about 1/4 of the old sand but I did not shift through the old shells and rocks. Should I do something for the bottom of the tank?

Added salt 12hrs ago and its starting to clear up when will it be a good time for me to add the sand ?

Can cabbage coral be kept on the substrate? Will the tissue be irritated? I rarely see any sand covering it and it seems happy but for the bottom half touching the sand. It never seems to as fully extend. Should I prop the rock it’s on up off the sand?

Hi First time here setting up a 75 gal mixed-reef. I am getting ready to set up and cycle the aquarium and want to know if I can use a wet sand (Caribsea AragAlive) sand with my initial cycle plan using dry-rock and a Microbacter Dry Rock Bacteria Starter Kit - Brightwell Aquatics. Will this...

Video link - https://photos.app.goo.gl/3CzxWx1eNGEQtwDfA So I bought a new condo in Ft Lauderdale and inherited a mature marine aquarium. Which is great, because I always wanted one anyway, and am glad I don't need to set one up from scratch. I have a lot of experience with Freshwater tanks of...

Hi everyone! I just bought some CaribSea Arag-Alive reef live sand today, used what I needed, and have 11 pounds left. It’s the coarser Reef Sand size, and it’s available for $15 if anyone needs it. It’s fully submerged in the water that was in the bag originally, and still includes the...

Hello fellow saltines, I'm looking for some suggestions regarding my pistol shrimp moving sand around. Firstly, I knew these little guys were busy beavers when I got him so that's not my query. My pistol and I do this daily dance where he moves most of the sand from one side of the tank to the...

I’ve got a 200 gallon peninsula build I’m planning to transfer my existing Reefer 350 into. The BRS videos sold me on Caribsea Ocean Direct sand as I wasn’t a super fan of my current sand and I liked the idea of hopefully bringing in the bacteria from the direct ocean sand. Unfortunately, the...

For brain coral, do you need to add a frag base before placing it on the sand? Or just place it directly on the sand

Hello fellow saltines, I started up my 5g tank almost a month ago with CaribSea Fiji Pink live sand. Over the past year I have been researching how all of the different elements of a reef tank interact with each other and how they affect tank parameters. One of the things I read is that some of...

i’m getting a 75 gallon custom made. i really like sps tanks but everyone says less sand or no sand because it’s easier to clean. but at the same time i’m considering jawfish which need sand and i really like more "biology" in the tank. the scape will also be quite minimalist. how can i...

I was rinsing my Caribsea sand and noticed a large black flake in it. Upon inspection I discovered that it was a coin sized piece of rusted metal, and after running a magnet through the rest of the sand I found many more particles. To test for holes that could have allowed this metal to...
