new tank advice

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...

The alkalinity in my tank seems to be dropping steadily (about .1 dKH/day) independent of the other parameters. All parameters are tested daily because my humans are new to reefing and want to understand how everything works together. The other parameters remain relatively steady at: Temp...

Hello reefers, My name is Ghost and I am a tiny marine hermit crab. One day in September I was just minding my own business, sifting Caribbean sand, when some loud divers thought my beautiful shell was empty and took it. Upon returning home and discovering my existence, they promptly set up a...

Hi so I have a pretty new tank, only 5 months old about, and I have two things I am questioning. First, I had somewhat high phosphates in July they were about .48, and my nitrates have never been higher than 6ppm on my Red Sea test kit. But I have a lot of green hair algae, which I thought came...

My brand new Red Sea max 650 is arriving on Friday, which will replace my first 55g tank. My current fish stock is 2 yellowtail damsels, a six line wrasse and two black percula clowns. Basically I have 5 ****** fish that will be moved into the new tank. I would like some advice on what fish...

In my most recent Reef this is my first addition. Build thread coming soon. "Show me what you got!"

Hello! I'm getting ready to set up my first saltwater tank. My husband has had large saltwater tanks in the past (75+gal) but I'm just trying to set up a 30gal for 2 clownfish, an anemone, maybe some shrimp, and a starfish. I'm not sure if/how much coral I might get as I still need to do more...

Hi All, I have started fishless cycling with Dr tim's in my 50G tank with Live sand and dry rock. It took about 3 weeks when I got 0 Ammonia, 0 nitrite. As suggested in other threads ,added 2ppm ammonia again just to confirm if my tank is actually cycled . And it took 4 days to get 0 again...

Hello guys, I'm new to the saltwater world, and I would love to hear some suggestions about which fish should I put in my tank, I already have a pair of clownfish and a shy juvenile yellow watchman goby (hoping he gets a lil bit more brave as he grows, if you have any experience with that fish...

Hello All, I am upgrading from a BioCube 32 to a 75 gallon display with a 20 gallon sump. Finally got permission because my aiptasia problem is out of control. I am currently transferring fish to the new tank, and will start with coral soon. The problem I am running into is that I can’t seem to...

Hello, am new to the saltwater hobby, my tank have been cycling for 12 days today, and my water parameters are ammonia: 0,2 ppm, NO2: 0,5 ppm and NO3: 10 ppm. Is it save to put in some soft corals? sorry if it is a stupid question

Hello, I set up a 15g nano tank last week to hold two fish sent by my son (firefish and a neon goby). I used two pieces of live rock that I purchased plus a sponge from my established 45g. 50% water from established tank and 50% new water The LFS said I could put the two fish in right away...

Hi Everyone, Long time lurker on this forum and recently got into the hobby (5 weeks marine, but 2 years freshwater). I set up my Red Sea Nano Max 75L 5 weeks ago with the included protein skimmer, Red Sea live sand, a couple of dry rocks, Marine Pure filter media spheres, and RODI water with...

I'm currently working on getting a 165 gallon tank set up and am trying to do as much as I can to get it running smoothly now, rather than trying to catch up later. I'm not extremely familiar with UV sterilizers but I've yet to find anything about using 2 different ones to cover the...

I have my Biocube 32 tank going now. Not much In it other than clean up crew and a tree coral that hitchhiked in. But after reading so many posts I’m starting to see the benifits of a quarantine tank. I originally wasn’t going to do one do to space limitations. I have very little room to run an...

So, I’m coming up on a year in June for my first tank and there have been so many ups and downs. The one down I just can’t seem to shake? Algae. I’ve improved filtration, flow, removed stock, reduced feeding and light exposure (time and intensity). I just can NOT shake the algae. A couple...

I have been extremely patient going through my cycle and it’s been quite fun but I’m tired of it! Does anyone know when the different types of algae will start to disappear? my tank is 6-8 months old and my nitrate is sub 5 ppm. Also, how can I control green hair? it’s getting bad..

Hello! I will summarize at the end and provide photos if you don't want to read my initial tank journey from start to now, but here we go! I included the journey only because maybe there was a misstep I took that can explain things. Look for the colored markers if you want quick notes, and...

Hello all! I've been lurking for a couple days and figured it's about time to jump in and see if I can get some answers on my current situation. I inherited a saltwater tank that hasn't been used in years so my wife and I have been cleaning it up, restoring the stand and investing in making this...

Hello everyone! I am looking to upgrade from my nano 30 to a 50 gallon cube. Here is what I have for my stock list for far. Please let me know what you think. The ones that say current are currently getting along in my tank. Thanks! 2 clowns (current) 3 chromis (1 current) Midas blenny...

Hello, I just signed up for this forum and I have been out of the saltwater aquarium game for 15years. I recently purchased a WaterBox Mini Peninsula 25 gallon for my birthday in January from worldwide coral and staff member Dre was very helpful. The tank has been set up for a month. I just...

I am setting up a new tank in the next few months and I have decided on the Waterbox X60.2. For ones who don't know this is a 40 Gallon Reef Cube with a 20 Gallon sump in the bottom of the stand. I am in college so I am on as much as a "budget" as is can be. At the same time I don't want to...

Hey my name is Erik. I have been doing reef tanks since 2003 but have been very laced in the hobby. My friend gave me my first tank for 300. It was nice 75 gal with sump and skimmer t5 and halide. I think all I had to buy was power heads. My fish stores in santa cruz suck so I learned everything...

I need advice and help from some reefers who have some experience. I want to start my first saltwater tank. In the past I’ve had freshwater and planted tanks, but never saltwater and certainly not with live corals. I have been interested and done some research over the past four years. My friend...
