Building My Floating Reef: A Long Overdue Post This project has been a long time coming, and I’m excited to finally share how I built my floating reef. It all began when I purchased the newly released RedSea Max Nano XL G2 system. With the limited footprint of a nano tank, I wanted to create...

Hi team! I’m wondering what you all think the best fish is/are for a 20 gallon frag/growout tank? I’m probably going to go bare bottom and minimal rock - just enough to cycle. Bonus points if it’s aquacultured.

Hello Reef2Reef-goers! I'm setting up a pico reef in my college bedroom and figured I would put together a build thread. The tank I landed on was the Lifegard Aquatics Crystal 3.8 AIO. The build quality is good, clean seams, clear glass, no complaints. On the other hand, the pump that comes...

I just got my first AIO nano and I’m not sure what the best set up for each chamber is? I currently have live rock rubble, chaeto, and filter floss but I am trying to ditch the chaeto in such a small system it makes less sense. What works well for you guys? I currently have a 125 gallon with a...

I currently have a water box 65.4 AIO tank. I’ve been trying to find a UV sterilizer that will go with my tank since I have a AIO. I have an Axis 90 return pump. The goal for wanting UV sterilizer is to get rid of bad bacteria, parasites, and make my water clarity crisper. Any suggestions would...

Just picked up this drop in manual fleece roller for my IM 40L AIO. Really happy with the placement next to the protein skimmer but I have a question. What do I put in the open space at the base of the plastic towards the cone end (pictured). It looks like a place for additional filter media...

Oddball AIO penn-plax tank I won, wouldn't have ever paid money for this thing. The tank was free, so extra funds to put into other equipment or livestock, I guess?I had a pico tank a few years ago that unfortunately crashed and I'd like to try saltwater again. Holds just under 11 gallons filled...

These are custom printed media baskets with lids,you can load up on all of your favorite media with these. most tanks require 3 to 4 in each media chamber. I do have a small stand that goes under them or you can use a filter sponge.there has to be something on the very bottom for flow to the...

Is there someone that can walk me through how to properly setup my automatic fleece roller, specifically how to determine the correct height to place the ATO float switch in the rear chamber of my AIO? I have a 20 Gallon IM Nuvo Fusion Pro 2 AIO. Currently I have the Tunze Nano ATO float switch...

I'm setting up my dosing lines in the return chamber of the rear of my AIO. When I put the return pump in feeding mode, the water in the rear of the AIO reaches the dosing lines (which includes my ATO line). Is this an issue? Is there a chance for siphoning (either into or out of the tank)? When...

I purchased the tunze 9004 DC unit and placed it in the far right rear chamber (of aio) figuring this would be the best placement, but I cannot get it to produce any foam. I realize it being placed in this chamber it will not do any surface skimming other than what is being skimmed from the tank...

Hello! The purpose of this post, and future posts, is both for newcomers and for my own selfish reasons. I’m going to be starting a 25G AIO and will note as much of the process as possible. I want to help create a standard guide for those with similar goals and hope in return to receive advice...

Hey everyone, I was playing with the idea of building a sump/refugium in my AIO chambers for my waterbox 25 peninsula. I removed the black backing so I could see back there and I definitely think I could do it. Anyone experimented with this? Couldn’t find any pictures or videos online that...

Hello, I’m hoping for your help I’m about to start my first tank and I wanted to get a gauge on practicality. It’s my first tank and I’m going for relative simplicity, I would love any advice. I’m going to get a 25 gallon peninsula aio. Due to size and other factors I will not be using a sump...

I've got a brand new Waterbox 15 gallon peninsula tank all in one. It's still in the box it was shipped to me in. I just dont have the time to do another tank. I also ordered the mesh lid. With shipping and tax I paid almost $350. I will let it go for $225.00. If you need pictures thats fine...

Finally getting around to selling my old setup. Tank is an Innovative Marine SR-80 Pro 2. It was set up for about 2 1/2 years before I upgrade to the SR-120. No leaks while I had it running and seals are in good shape. There is one small scratch on the front pane and some on the black acrylic...

As the title suggests, I'm looking for thoughts on what to put in each of the three filter chambers for my WB 25 Peninsula AIO tank. I have been testing weekly and I am not controlling nitrates well. To keep nitrates low, I have to do multiple water changes a week right now. Currently, I just...

Hello! So many places referenced R2R as an amazing resource, so I decided to join and document my journey with my first saltwater tank! I have two successful small freshwater planted aquariums and I'm looking forward to seeing what new challenges this will bring. I first set up this tank on...

Hello! I have my 20 gallons IM AIO 4 months ago. Everything went good until like 2 weeks ago. I start having issues with the alkalinity all the other parameters are stable but the alkakinity is going up every day. Today: -O2: 8 mg/L -Sal: 1.025 SG -Alk: 11.8!!!!! ??? (It was at 11.2 and is...

Would you always go for a predrilled tank? Or prefer the standard? What reason? The standard version plus a hob overflow cost nearly the same as this seapora drilled.

Not new to reefing but new to an AIO. I had a 180g w a sump but have since downsized to IM 25g lagoon and am having lots of trouble. I started w a sicce synced silent 1.0 pump and it seemed like it was pushing water faster than it can drain. I have since downsized to the same pump just the .5...
