tank size

Hello fellow reefers! I have kept my 85g reef tank for a while now, I live in a top floor flat and get my RODI water from a water station in 4 x 25 Litre jugs, 2 for salt, 2 for plain. I tried to run a filter however it just took too long to get the amount of water I needed and do far the...

New to the hobby, and have about 41" of wall space I can put a tank. I am ready to click the buy button and I have done a lot of research, but can't decide on the tank. I plan to keep LPS & fish, no interest in SPS. My key criteria is success in keeping fish & coral and low maintenance. I want...

Thought about getting a one spot fox face For my 5ft 125 gallon tank for algae control, but got conflicting information online about tank size. Would my 5ft tank be good for this fish for the long term, or is it too small?

I'm on the fence on whether to move my clownfish pair to a different future tank... Maroon/Percula. The tank is a 12x12x12 with an external overflow. While the DT is small. The actual water volume will be roughly 15-17 gallons when including sump. Thoughts? I think it will be fine. But wanted...

So I am planning a 5 gallon tank, with macroalgae, soft coral, and some sexy shrimp, and think a central fish might be cool. I checked the lfs and they don't have anything smaller than a two-spot blenny. Can I keep one, or should I look for even smaller fish?

Hi Everyone, My EVO 13.5 is a little over a year old and I have 2 pcs of coral ( I think a Kenya Tree and Toadstool Leather) that are beautiful but I am nervous are overtaking the tank and hoarding light. Any recommendations? Upgrade tank size....Pruning. I also have some Daisy polyps that I...

Hey! I recently downsized to a 4f 60 mixed reef…. I have a small blue regal. I understand after a couple of years I will have to switch him out for a smaller one but can I get away with him in here for now? He’s 1.75in

I purchased a Black Indian Trigger about 2 months ago. He was at my LFS for a few months, I finally broke down and got him. Currently he’s in a 75 with a Maroon clown. Live rock tank with lots of Macro Algae and a couple coral. I know a 75 is too small. The trigger is about 4” and from what...

Hello Reef2Reef Community! As I was cleaning my tank yesterday, I realized that in two months it will be 1 year in this hobby! I was thinking about how much I have learned throughout this experience and how many errors I have made along the way because I was not properly educated. Some of my...

I’m looking to upgrade my system. I currently have a clown trigger and a snowflake. I’ve been looking at Waterboxes and wanted opinions on the appropriate size tank. I was looking at the Waterbox 230.6. Do y’all think that’s big enough for the trigger?

Hello everyone, I am planning to have a Zebrasomas scopas and need some advice from people that have experience. My current tank is only 100 litres (80x35x40 cm) and I want to upgrade to atleast 150 cm maybe 180 x 60 x 50 cm tank. I want to build d the hardscape dedicated to the scopas, so it...

Hello All, wondering what the best size tank for a condy is; I’ve seen min size listed as 30-50G online, but don’t want to get a 40 & end up with this beautiful beast outgrowing that too lol Background: I was given a small, established tank, 5mos ago, with a gorgeous condy who hosts my 2...

Hello everyone! I am excited to join this forums after lurking and reading for months. I apologize if this is a repetitive question, but I didn't really the exact answer I want. Also I want to pick the brains of seasoned reefers to steer me in the right direction. Here's my dilemma. Read a lot...

I recently got a red stop light cardinal from my lfs for my 15 gallon cube tank. I was wondering if this was actually enough space for one because I couldn’t find much information online for them at all. I was also wondering if anyone else has had any experience with these guys

So! I'm one of those people that tried to keep a snowflake with fish, and while it's worked out so far. I'm slowly starting to see her get nippy towards fish on feeding day so when I move my fish and coral to my new tank, she is going to stay in the 4pg cube until I find a suitable new tank...

What’s up guys, after having fun with my fluval 13.5 I decided to finally get an actual sizable reef tank a NUVO 40L, so now I’ve got the tank setup and cycling and I’m planning out the stocking choice for it all. I want to make a mixed reef with this tank but I also want some more interesting...

Even since getting into fishkeeping, I've wondered where the minimum tank size numbers actually come from. Early on, I heard of the inch per gallon rule, which although it had many exceptions, was pretty easy to follow. But now I'm just curious where these new numbers come from, especially since...

I live in a small apartment, and I'm wondering how small can a coral quarantine be, provided I only want to test for Alkalinity once a week? I realise that Alkalinity consumption is not gonna be huge in a quarantine tank, but still.

Hello fellow saltines, Today is the first full run through of my AI Prime, using Saxby, on my 5g (in acclimation mode). My question is: If I like everything about the Saxby preset then is there a calculator or general scaling formula related to tank depth? Ex: I read that David Saxby's tank is...

Hello All, I am looking to begin inquiring around to have a custom made tank made. The only problem is, how will I know what the tank size will look like? Is there anything online that I can type in size dimensions and it will create a rectangle image? I have been thinking about a 48x27x24 inch...

I know you can go DYI, but if you go Red Sea or Waterbox, there's no way around it. You need to buy a larger tank to have more cabinet/sump space. I've DYI'd my first tank, a 50G, the result wasn't bad at all. My dad is a mechanical engineer with his own workshop, and he helped a lot. But after...

I recently purchased a 65 gallon Red Sea tank on Offerup. The owner was including all of his livestock along with the tank. One of the fish included was a fairly large blue tang (about 6-7 inches). I understand that he is likely too large for this tank but I had no choice but to take him. What...

Hello everyone! I was at petco the other day (I know dont buy fish there...) they had a leopard puffer for sale for $5 and was in freshwater tank. ( i did buy him) These fish can live in fresh or brackish when young (he is 1 1/2 inch) but as they get older they need full marine. I have a 20...

Hi guys I currently have a 4ft 165 gallon(DT Volume) tank (4'X2.5'X2.5') and would like to purchase a convict tang. I'm not sure if I'll be overstocking my tank or if the tank is too small for an adult sized convict tang. I'd like to hear other's experiences with convict tangs and their usual...
