nano

Hey everyone! Just want peoples opinion and input on my future tank build. I have debating between these two tanks for a couple weeks now and have no idea which one I should go with. I just took down an Innovative Marine 25 Lagoon due to me moving, and I can’t say enough good things about their...

Hello all! I'll be frank - I'm completely new to saltwater tanks, ended up on a coral youtube a while ago and was honestly dumbstruck. This is the coolest thing I've ever seen. I have had freshwater tanks in the past, loved it and miss it, and I'm confident that with some research and practice I...

14 gallon peninsula 2.5 years old

Please attach picture or video of your nano reef tank, or maybe a different kind of tank, must be 20 gallons or under. Cheers!

I decided to check my temperature today on my 32.5G, and it’s reading 85 degrees Fahrenheit…. All my fish seem to be okay, not gasping for my air or anything… All of my corals are good… I just have some gonis that won’t open up all the way but I’ll be testing my other parameters later this week...

Several life changes and home shifts later, I still haven’t set up my first tank. I’m not going for size here. I want some colorful anemones & soft corals, preferably self-sustaining. Thinking about where I could put one in my apartment, the best spot seems to be the mantle above the...

Hello, I am thinking about small 40x40x40 (64l) anemone cube. I'd like to keep there a cleaning crew, 2 clownfish and a bunch of anemones (like quadricolor bubble tip and similar ones). I would like to run it with a cascade filter, well developed biology from a living rock and sand, use extra...

This tank had a very rough start. Everything you can imagine has happened. Large parameter swings, equipment mal functions, rookie mistakes, pests, and even a stroke of bad luck LOL. NOW 8 to 9 months later, the tank is starting to mature more and coralline is growing at a nice pace corals are...

Hi 👋 Completely new here and new to fish! I have a standard Fluval Sea 13.5g with no modifications (yet!) Bought this “rock” from my LFS which had been in their sump for 4/5months. With Caribsea Fuji pink live sand. All I’ve got in there at the moment are some tiny shrimp-type creatures and a...

Hi Reefers My names Rory aka Toast I've been browsing R2R for a few years now but I'm going to be starting my first Nano soon (40 gal display with 8 gal sump) and will probly log my process as it comes along. I've been beefing for about 2 years now with Pico tanks my current setup is a Nuvo 8...

Hey all!! Can't say whether or not I'll be super active on updates here for my build, but I figured why not share my experience when I manage to remember! I started this tank around a month ago (March 2025). It's a UNS 45A dual AIO tank, roughly 9gal total. I've had a handful of different tanks...

Help please! I just can’t figure out what I’m doing wrong. Tank is 3 months old. Fish are perfectly fine. But I can not keep corals happy in the slightest and all herbivorous cuc dies within a few days of being added to the tank. Worried that the bright green on the rock is some form of cyano...

Hi Everyone! After a long hiatus, I realized how much I was missing the fish and came back with a small desktop aquarium that I could enjoy on my WFH days. We're definitely in the ugly phase, but I have a bunch of small frags I can't wait to see grow out and take over. It's already making me...

Ignore the mess in the back, but this is what I have put together for my aquascape! There will be a good-sized island to the right, and maybe some other rocks on the sandbed. I have a group of 12 sexy shrimp at the aquaculture lab that will inhabit this tank until it is ready for 1 fish (red...

Hey guys! Currently I have a a Hygger 50w LED light and I wanted it mounted to my ceiling but the hanging wire is only so long. I feel like the light should be closer as it’s 2 feet away right now and the tank is roughly 12-15 in deep factoring in sand. Thoughts?

Hey everyone, I was wondering if it’s safe to feed my inverts (Cleaner Shrimp, Halloween Hermit, Scarlet Hermit Crab, and Electric Blue Hermit) small pieces of frozen or thawed uncooked restaurant-grade Black Tiger Shrimp. I want to make sure this would be a suitable and nutritious food source...

Hi there, I recently discovered my water levels were too high and I normally have my heater in the return chamber of my waterbox 25, but with reducing the water level it makes it difficult to submerge it and I'd rather not put it in the display tank. Any suggestions? I'm curious how people...

Hey guys! Been browsing this forum for months and finally decided to finally make an account! So I have a cycled 20 gallon tank and am considering the following for stocking, just curious if this seems like a good idea or if it’s too many or incompatible fish? Pink-Streaked Wrasse Sharknose...

Really quick question, do I need a saltwater test kit if I have premixed saltwater from a lfs, and I do weekly water changes? I don't see the need for them, if I detect something wrong with my water, i'll do a water change, and if I dont, i'll still do a water change. (nano tanks if that helps)

Hello reefers, I've decided to do a little build thread of my Waterbox Peninsula 25 tank which I started in December 2024. I have always kept freshwater fish and never looked at Marine due to the high costs but after doing some research I realised it shouldn't be too expensive compared to my...

I was about to buy a MiniQ Nano Skimmer until I realized that the ReefCasa Protein skimmer was identical. This made me think, they must get them from the same manufacturer. So i checked Alibaba and sure enough i found exact copies. I guess my question is. Do you think they are the same quality...

Hello everyone! I hope you are doing well. I was curious if I could put this anemone in a 10 Gallon aquarium—side note what anemone is this? There won't be any other critters for the anemone to worry about—just an anemone tank! Maybe some macro algae eventually. Is this okay/humane? I...

After leaving the Hobby for 10 years I decided to dive back in! Tank is two months old and I couldn’t be happier with the progress and finally applying the knowledge I’ve learned over the years! (Keep pests and Algae away) To cycle tank dry rock, live sand Half bottle of Ammonia Chloride and...

Hi everyone, I have a 15 gallon nano almost a year old. Unfortunately, it is the coral 12G tank, so I'm aware the pump and lights are not the best, but I've slowly been upgrading it. The tank has been fine but I upgraded all my testing kits and the phosphates have been obsurd. Parameters...
