20 gallon

After posting about my refugium over in the macroalgae forum I decided why not post up my whole build progression while I'm at it. First off, I suppose this would be considered a budget build by most standards, and/or DIY, nearly everything was repurposed from old builds during my last foray in...

Hey y'all, I'm a brand new reefer from Toronto Canada and I'm very excited to share my journey. From a young age I've been captivated by marine aquariums, now finally having set up my own I still feel that same youthful enthusiasm every time I look at my (mostly empty o_O) tank. Reef2reef is...

Hi! So just like the title hints at, I'm getting a new UNS 60U to replace my 5 gallon the cracked and broke. And seeing as the dimensions are quite strange: 23.6L x 14.6W x 14.6T , so I feel like I need to change up some stocking options that would fit a standard 20 High or 20 long, so, any...

Hello, I’m getting a 20 gallon waterbox tank that I will be growing corals in. The tank can come with AI Primes, but with a 200 dollar increase in price. Are there any good, affordable options(less than 100$) for lighting(for corals)? The dimensions are 18in x 18in x 16in.

Hey guys new to this website but not to fish keeping! Ive owned a saltwater tank before was 45 gallons when I was younger but its been awhile dang thing cracked while moving and that was that. Are these fish okay for a 20 gallon? 1 Coral beauty angelfish (bought as baby) 2 regular clownfish...

I'm new to saltwater aquariums and I would like to set up my nanoreef but I don't know if I should go for a 10 or 20 gallon tank. I know a 20 gallon tank would be more stable. I will be keeping this tank while I live in my apartment by myself and studying in university.

Just thought I’d share this video of my new 20G High aquarium. Going to be picking up some live rock with some mushrooms and green star polyps from a fellow hobbyist. Can’t wait until it’s all aquascaped! My clown doesn’t know what to do with all that swim space!

Hey my name is Anthony and I’m..back!! Well I’ve been without a saltwater tank for awhile now. And have to say it was tough and a sad time without one. Seriously boring! After researching and studying different size tanks, and complete packages I choose the little Red Sea max nano. I’ve always...

Hello fellow reefers! So i have decided to start a new tank (not my first or 2nd). I'll be going for the Innovative marine 20 gallon long peninsula all in one tank. So now i have to pick a light fixture that can have full coverage of the tank as i will have it setup in a peninsula style. I...

New to Nano's but not to reefing! This is my first post on R2R. - Just bought the tank at the Petco dollar per gallon sale for $20. - Removed Rim with a hot wire and hot knife to melt plastic and silicone. In the next week I will be basing my design off the Innovative Marine fusion 20g...

20G Long Nano

I need some advice on heaters for a new, still cycling, 24 gallon saltwater tank. Right now I have an older Eheim Jager 75w heater, but I'm not sure it will be enough for the tank for winter. You see, I previously lived in the SW United States and never had to use a heater on my saltwater tank...

Hi, I am upgrading to a SCA PNP 50g and want to sell my my other set up. It's a waterbox 20 gallon AIO cube with a black wood aftermarket stand. Its only been set up for about 6 months, in perfect condition. I also will throw in the skimmer, the skimmer is a Macro Aqua m-50 Hang on Back. Tank...

Hello all , my name is Brian. I am not new to reef keeping, it’s a passion that I hold true to my heart and helps me disconnect from the world. I was recently faced with a hard decision, life was pulling me away from my tank which is a 55 gal cube. I did not want to give up the hobby because I...

Hey guys, I'm planning a tank that will basically be a reboot from my first nano tank that I decided to tear down and re-do. With the space, I realized I can upgrade from a 10 to a 20H, and while I'd much prefer a 20L, I don't have the space for it. But if I can fit more water volume that'd be a...

I have a painted frogfish (Antennarius pictus i believe) that i got on Saturday (5 days ago) I fed him a feeder fish on Sunday because the fish store had him on an every other day diet so i thought it would be best if i was consistent. He ate it with no problems. Then on Monday i noticed when i...

So I picked up a 20 gallon tank that was previously set up with very well cured live rock. I cycled the tank keeping an eye on parameters and it has stayed at 0 PPM for Ammonia and Nitrate. Is this common with a previously established tank? I filled with RO/DI water and used instant ocean salt...

*For starters i would like to say that there is no fighting in my tank, they all actually have a good amount of space im more concerned about the bioload in the 20 gallon, so give me tips, please. So, Basically to put it simply i fear that i have over populated my 20 gallon long tank. These are...

hello to anybody reading this, I recently bought a Nuvo fusion 20 gallon tank and wanted to try out this amazing hobby. I know that beginners are recommended to get at least a 50 gallon tank, but I have no room in my small apartment. Anyways, it’s been about two weeks since I’ve added my sand...

Hey guys, this is my first time with a saltwater tank and I was planing on starting with a clownfish tank. I've had a freshwater tank with goldfish for a while, and always had no lid on the tank, because it seemed to me Rabat gold fish can't jump. But now I just realized that clownfish can jump...

Hey guys, how is it going? This is my first time at reef2reef, and my first attempt at a saltwater tank. I've had a freshwater tank with goldfish for about a year now, and decided to take the leap and start a saltwater tank as well. So what I'm paling to have is a 20 Gallon tank with 2 clownfish...
