nano 20

G'day everyone, Starting a build thread for my new Waterbox 20 AIO. Not my first marine tank - I ran a small AIO from June 2016, upgraded to a Red Sea Reefer 250 in December 2016, and shut that down in September 2022. After a 3.5-year break, I'm back at it with something smaller and more...

Tank: IM 20 long Heater: Finnex Titanium 100w Flow: stock return + Jecod ELW-5M Sand: ocean direct+TBS (on the way) Dosing: all for reef Probably gonna add a protein skimmer Light: Nicrew Gen2 I want to keep crocea clam, torch and hammer coral. I may add some SPS too.

Hey there! I have a 20-gallon Innovative Marine Drop off tank. I own a Harp tail Blenny and two bonded Clownfish. Recently in the last month, I had purchased an Indigo Dotty back that I had ultimately ended up bringing back to my LFS. He was such a gorgeous fish and was super bold and fun to...

Hello friends! I’m based in the UK and just purchased a RedSea Nano 20g (second hand). I’ve done a lot of research and I know that RedSea have some issues, but the tank I’ve bought seems in really good condition and the guy I’ve bought if off had a genuine reason for selling it. There’s...

Hi there, I’m new here and need some help with trying to figure out next steps. I’ve had my tank up and running for a month now and put in two clownfish as the starting fish. They were doing great with no issues. I decided a week and a half later to add a tail spot blenny and a purple...

I'm really new to the hobby and just set up my tank to begin its fishless cycling period. I've looked through some other threads, but want to ask some questions more specific to my tank and lights :]. First, some background info. I did some tests today, and my parameters are as follows pH 7.7...

Looking for some advice. I’m planning to get back into the hobby after a 10 year hiatus. I want to try a ULM (Ultra Low Maintenance) Nano Zoa Garden in a AIO 20 Waterbox. I sketched an idea for an aqua scape. The goal being to try and make it look like a botanical garden. The questions I’ve got...

Hello ya'll! I have an Innovative Marine Fusion 20Long AIO. It came with two 5W/24V return pumps each rated at 130GPH. I see that IM also sells the Mightjet 326GPH pump. Would it make more sense to have two pumps equaling 260GPH or one pump doing 326GPH? Right now i BARELY turn on my...

I just started my 20 gallons reef tank in January and I recently got Seachem Reef Plus Conditioner. I have noticed whenever I add it to my water(one a week) my Duncan Coral shrivels up and basically becomes...nothing, My frogspawn stays the same and I noticed my BRA kind of balls up too. The...

Building my first ever reef tank (I have had a few freshwater tanks in the past). I like the look and size of the 20g IM Nuvo Fusion AIO tank, especially due to my low-ish budget of $1.5k or lower and my 1bedroom apartment that doesn't offer a ton of room. Below is a list of the gear that after...

Hey Everyone! After a year, or so, of being away. I'm finally getting back into the hobby with a WB 20 Cube. I downsized from a 75 gallon where I DIY'd the stand, sump, and most other things in the system. I wanted to get a small AIO and finally put the money and time into the hobby that it...

Got a little upgrade from Fluval Evo 13.5 to IM Nuvo Fusion 20. I transferred some of the rocks from the old tank to start. I added a couple of fishes and corals.

It’s my first post here and probably going to be looking for some advice in the future. I had this IM 20g Peninsula for about 4 years , it was set up on my bar top but I hated that I couldn’t see all 3 sides. I built this Tank stand last weekend and just put some shelves in it. It obviously...

I am obsessed with this hobby and figured this would be a great way to keep tracks of my progress as well as share all my trials and tribulations. AIO Landen 26g 60p reef tank. 18mo into the hobby but I did move the tank into another room of my house 6 months ago...so basically started over...

Hello everyone. I have been looking at small crocea clam for my 20g nano tank. It's under 4months old with about 50 corals that's growing at a decent rate. Running a pretty high tech tank, with ALL FOR REEF dosing and kalkwasser dosing at night to keep ph above 8. Ph 8.2 Alk 8-8.5 Cal 420...

Hey guys I got gifted some Kenya tree coral by my local store who said that it is very weed like so shouldn’t have any issues growing it. I expressed my concern over my lighting as I only have white light and no blue and the assistant said it would be fine because I can grow macro algae etc...

Have the following inhabitants. Any suggestions on where I should place or move corals? Candy cane coral Zoanthids Kenya tree leathers Clove polyps Micromussa Duncan coral Hammer coral Frogspawn coral

Hey guys, just started the tank with 2x AI Nero 3 at random mode at 35% max, and struggling to understand if the flow is okay or might be improved, where to place the Neros. Could anyone suggest please? Also, my clowns are always on the back/near the overflow and lightly bullied by damsel...

Hello everyone! I've been an avid fish keeper for a long time, primarily on the freshwater side, but I'm excited to dive into the world of saltwater. I was inspired by a close friend who is in the hobby. Anytime I went to his place, I would stare at his tank the entire time, so I figured it's...

A little thread to document my little tank. I filled a 20 gal long with saltwater about 2 weeks ago...maybe 3...not sure when actually. I just thought a glass box of saltwater might be cheerful. I modified an AquaClear 70 to act as a HOB (hang on the back) refugium / place to grow macroalgae...

Guys I finally got the first edition! The tank is 13 weeks old, full of copepods and I finally took the plunge with a Firefish! I’ve been waiting for the perfect one as I’m aware I’m limited on options and I think it’s so pretty! Would like to add 3 sexy shrimp in a couple weeks but any ideas...
