nano 25

I am starting a new tank build to replace my aging 30 gallon tank. It was my very first tank, which currently houses 30 bubble tip anemones. This new tank was given to me because it did not fit where the previous owner wanted it. It is an 18" cube with a frame-less top and low iron glass. So...

Hey everyone !! Starting my new reef build and wanted to document everything from cycle to full blown mixed reef. This will be a carefully planned mixed reef lagoon with strong flow, clean equipment layout, and room to grow Tank: Innovative Marine 25 Lagoon Dimensions: ~24” x 20” x 11.8”...

I have a confession. This tank has been up and running for ~2 weeks already. I won't tell if you won't 🤫. A late build thread is better than no build thread. I lied, I actually have 2 confessions. I also am not huge coral fan. They're fine, but they're not what really does it for me. I have...

Howdy! I wanted to go ahead and make this thread for my journey building my tank stand and system. I have a lot on the list, but as a broke college student, I am... well... broke! I will be over time updating this thread to update my progress and experiences. It has been one hell of an...

I started a 25g nano about 3 months ago and I want some suggestions on fish. Currently I have two clownfish and a helfrichi firefish. The helfrichi is pretty shy and does not swim around much which is pretty irritating and I'm wanting more movement in the tank. I'm planning on getting a citron...

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...

I was planning on getting a IM 25g lagoon tank but unsure whether to get the starter kit or the fusion pro 2? The starter kit is like half the price, so is the fusion pro worth it? From my research the only main differences is that the pro tanks have the mighty jet DC return pump, custom caddy...

Hey everyone I have this 25 gallon cube that I was given and it currently is running a Red Sea 50 light but I’m seeing very little growth from most of the corals and all the colors look very dull. I have an extra AI prime laying around and was wondering if it would be better. I have AI on my...

So, we put together our 25 Gallon Nan - Rock & Sand added - Water added from local LFS - It has been 2 days now, water is clearing out. I have not added any additional liquids, waiting on the Fritz 9 which will arrive today and I will add their recommended dosage. I also have not turned on...

Jbj sf25 - 18” cube I have a filter sock, a small bag of carbon and the original return pump. What should i put in the back any suggestions to start off the bacteria good? I want to put in water this week and want to make sure we start correctly.

Hello guys, I recently bought a peninsula 25 from my local shop. It was fine until return pump which was included with the tank started to have problems as there was not enough water in the return pump area, this caused air bubbles and loud noises which I have been trying to solve. I don't think...

For fun I've been messing around with adding an overflow box to a water box 25 gallon peninsula in order to have a sump in the stand. In doing so I found been using a nano refugium I can fit and automatic fleece roller a full size protein skimmer, an algae reactor, as well as media reactors...

Hello all! More so just doing this for fun feel free to follow along. Over the next few months I’m going to be actively working on building a dream mini tank in my apartment. My end goal is to make it a mostly sps tank with a few softies or hammers to fill in gaps. Eventually the long term...

Hello everyone! My nano reef has been running for about a year, and I am going to start my tank build thread (better late than never). I’ll start with some photos, then get an equipment list out. From there we will see where it goes!

Hello! I'm starting up a 25g nano tank. It's my first tank, I'm looking at adding my first fish in the near future once my tank has completely finished cycling, but I'm not sure about what order to put things in. Here's my Ideal Future stocking list, as it is right now: Clownfish x2 Banggai...

Quick question I have for everyone, I am considering getting an IM 25 Lagoon. I want to get the NUVO Roller Mat, but since the 25 Lagoon has a dual intake on both sides would it be worth it to get a roller fleece only for one of the intakes? Also, what would be the best ATO for the IM 25 (Cheap...

Intro Hi Everyone. It has been awhile since I posted here, so hello again! I am starting a little project to downsize my current tank, which you can see here: link. I want to downsize to an all-in-one that will sit on my desk here: Backstory (Skip if you do not care) The reason for downsizing...

Hey everyone! My name is Galen. Thanks for stopping by my build thread. First time Reefer here, so please feel free to offer your thoughts, comments, critiques, etc. **Current Tank & Critter Shots** This is my first reef tank, a 25g Waterbox Peninsula AIO. A complete build list can...

PORTLAND METRO AREA, OREGON,- After several years in the hobby, I have found myself with little time to dedicate to my tank. I attempted to move it to my place of work, however, I am now moving into a new role and will not have any time to get it set up. I will upload several more photos into...

You're thinking, "ANOTHER 25 LAGOON?!!! . . . Well, Yes! . . . but with a twist. This one is MINE! ;) ;Cat I am limited in size due to my current apartment situation etc but I would love to have a larger (but still shallow) tank someday! Once I have my own house maybe. Originally I was...

So...Here is the goal...

Hey everyone, So, I was planning on getting a bubble tip anemone on Sunday and was puzzling over how I would prevent it from wandering into the power head (it’s a hydor koralia). I dislike the idea of trying to put mesh or something like that over it, simply because it might clog and would...

New Year, new tank... I finally pulled the IM 25g lagoon out of the garage, let the softie/mushroom tank build finally begin! Decided on the sandy bottom... better for mushrooms and easier to spot if they detach, future fish will need it as well. Water is in, taken from the main tank...
